description: Visual imitation learning provides efficient and intuitive solutions for robotic systems to acquire novel manipulation skills. However, simultaneously learning geometric task constraints and control policies from visual inputs alone remains a challenging problem. In this paper, we propose an approach for keypoint-based visual imitation (K-VIL) that automatically extracts sparse, object-centric, and embodiment-independent task representations from a small number of human demonstration videos. The task representation is composed of keypoint-based geometric constraints on principal manifolds, their associated local frames, and the movement primitives that are then needed for the task execution. Our approach is capable of extracting such task representations from a single demonstration video, and of incrementally updating them when new demonstrations become available. To reproduce manipulation skills using the learned set of prioritized geometric constraints in novel scenes, we introduce a novel keypoint-based admittance controller. We evaluate our approach in several real-world applications, showcasing its ability to deal with cluttered scenes, viewpoint mismatch, new instances of categorical objects, and large object pose and shape variations, as well as its efficiency and robustness in both one-shot and few-shot imitation learning settings.

description: Context. The chemical composition of planets is an important constraint for planet formation and subsequent differentiation. While theoretical studies try to derive the compositions of planets from planet formation models in order to link the composition and formation process of planets, other studies assume that the elemental ratios in the formed planet and in the host star are the same. Aims. Using a chemical model combined with a planet formation model, we aim to link the composition of stars with solar mass and luminosity with the composition of the hosted planets. For this purpose, we study the three most important elemental ratios that control the internal structure of a planet: Fe/Si, Mg/Si, and C/O. Methods. A set of 18 different observed stellar compositions was used to cover a wide range of these elemental ratios. The Gibbs energy minimization assumption was used to derive the composition of planets, taking stellar abundances as proxies for nebular abundances, and to generate planets in a self-consistent planet formation model. We computed the elemental ratios Fe/Si, Mg/Si and C/O in three types of planets (rocky, icy, and giant planets) formed in different protoplanetary discs, and compared them to stellar abundances. Results. We show that the elemental ratios Mg/Si and Fe/Si in planets are essentially identical to those in the star. Some deviations are shown for planets that formed in specific regions of the disc, but the relationship remains valid within the ranges encompassed in our study. The C/O ratio shows only a very weak dependence on the stellar value.

description: Les questions environnementales sont de plus en plus présentes dans notre quotidien depuis l’accessibilité à la ressource jusqu’aux différentes formes de pollutions toujours plus nombreuses et diversifiées. L’urgence climatique implique les politiques publiques dans une démarche de réduction des émissions carbonées et des consommations des ressources fossiles. Cependant la mise en pratique du calcul de ces grandeurs interroge. La méthode qui se détache, par son caractère multi-étapes et multi-critères, visant à représenter l’ensemble des impacts que les activités humaines exercent sur les écosystèmes, est l’Analyse de Cycle de Vie (ACV). Cette méthode nécessite une expertise, empêchant une démocratisation de son utilisation. Le recours à un outil devrait permettre de faciliter l’usage de cette méthodologie sur un domaine précis. Dans le domaine des ouvrages d’art, un outil d’ACV a été développé en Europe du Nord. Les spécificités du génie civil français et le besoin d’une évaluation à différents stades de la vie du projet ne permettent pas son appropriation par les acteurs français. L’outil CIOGEN pour Calcul des Impacts des Ouvrages de GENie civil a pour objectif de calculer les impacts de la construction d’un ouvrage d’art lors de trois phases du projet : l’avant-projet, l’appel d’offres et la réception de chantier. Le présent article décrit les principes méthodologiques de cet outil en abordant entre autres les questions de pertinence des données, de mise à jour et de représentativité.

description: We present a hydro-geomechanical model for subsurface methane hydrate systems. Our model considers kinetic hydrate phase change and non-isothermal, multi-phase, multi-component flow in elastically deforming soils. The model accounts for the effects of hydrate phase change and pore pressure changes on the mechanical properties of the soil, and also for the effect of soil deformation on the fluid-solid interaction properties relevant to reaction and transport processes (e.g., permeability, capillary pressure, reaction surface area). We discuss a 'cause-effect' based decoupling strategy for the model and present our numerical discretization and solution scheme. We then identify the important model components and couplings which are most vital for a hydro-geomechanical hydrate simulator, namely, 1) dissociation kinetics, 2) hydrate phase change coupled with non-isothermal two phase two component flow, 3) two phase flow coupled with linear elasticity (poroelasticity coupling), and finally 4) hydrate phase change coupled with poroelasticity (kinetics-poroelasticity coupling) and present numerical examples where, for each example, one of the aforementioned model components/couplings is isolated. A special emphasis is laid on the kinetics-poroelasticity coupling. We also present a more complex 3D example based on a subsurface hydrate reservoir which is destabilized through depressurization using a low pressure gas well. In this example, we simulate the melting of hydrate, methane gas generation, and the resulting ground subsidence and stress build-up in the vicinity of the well.

description: Every ten years, the containment buildings of nuclear reactors are tested through a 4-bar relative pressure loading with dry air in order to characterize the leakage ratio through the walls. The experimental and numerical studies (MAEVA, VERCORS, etc.) have shown that both leakages through cracks and through porosity play a significant role in global leakage. In particular, the flow of fluids through these cracks is impacted by their opening variations, their tortuosity, their roughness as well as the presence of occlusions, branches or crossings between cracks. The developments toward a three-step chained model based on weak coupling between Finite Element-Discrete Element-Computational Fluid Dynamic are presented. The aim is to predict the leakage ratio of dry air through a thick cracked RC wall. This estimation will allow the prediction of the air-vapour leakage knowing the leakage of air.

description: The large arrays of magnetic dots are the building blocks of magnonic crystals and the emerging bit patterned media for future recording technology. In order to fully utilize the functionalities of high density magnetic nanodots, a method for the selective reversal of a single nanodot in a matrix of dots is desired. We have proposed a method for magnetization reversal of a single nanodot with microwave excitation in a matrix of magneto-statically interacting dots. The method is based on the excitation of collective modes and the spatial anomaly in the microwave power absorption. We perform numerical simulations to demonstrate the possibility of switching a single dot from any initial state of a 3 by 3 matrix of dots, and develop a theoretical model for the phenomena. We discuss the applicability of the proposed method for introducing defect modes in magnonic crystals as well as for future magnetic recording.

description: We demonstrate the use of an ordinary white-light microscope for the study of the q-dependent dynamics of colloidal dispersions. Time series of digital video images are acquired in bright field with a fast camera and image differences are Fourier-analyzed as a function of the time delay between them. This allows for the characterization of the particle dynamics independent on whether they can be resolved individually or not. The characteristic times are measured in a wide range of wavevectors and the results are found to be in good agreement with the theoretically expected values for Brownian motion in a viscous medium.

Effect of Mainshocks-Aftershocks Sequences on the Lifetime Performance of a Liquefiable Soil Foundation-Embankment System

description: Structures should be designed to resist multiple seismic hazards during their serviceable life. However, among these hazards, the clusters events of mainshocks and aftershocks might induce structural collapse. On the other hand, it is known that the Performance Based Earthquake Engineering (PBEE) methodology presents limitations in accounting for the damage issued from multiple events. Thus, the fragility exposure of the structure cannot be determined due to the dependency of these events. For this purpose, this work proposes a methodology to study the response of a liquefiable soil-foundation embankment system subjected to sequences of mainshocks – aftershocks. Thus, for a given lifetime duration, the damage accumulation is calculated after mainshocks generated stochastically and aftershocks generated with the BASS (Branching Aftershock Sequence) model. Consequently, the survival probability was estimated as to evaluate the performance of the embankment. Finally, the lifetime fragility evolution of the embankment was calculated. The results of this work show the importance of the soil history of loading that affect the future behavior of the embankment. In addition, the aftershocks can result into more damages even if they have less magnitude than the mainshocks.

description: "Selected late-breaking clinical trials presented at the 2005 and 2006 annual scientific meetings of the ACC, AHA, and European Society of Cardiology, as well as selected other data, were reviewed by the standing guideline writing committee along with the parent Task Force and other experts to identify those trials and other key data that might impact guideline recommendations. On the basis of the criteria/considerations noted above, recent trial data and other clinical information were considered important enough to prompt a focused update of the ACC/AHA/SCAI 2005 Guideline Update for Percutaneous Coronary Intervention (3–13). To provide clinicians with a comprehensive set of data, whenever possible, the exact event rates in various treatment arms of clinical trials are presented to permit calculation of the absolute risk difference (ARD) and number needed to treat (NNT) or harm (NNH); the relative treatment effects are described either as odds ratio (OR), relative risk (RR), or hazard ratio (HR), depending on the format in the original publication. Consult the full-text version or executive summary of the ACC/AHA/SCAI 2005 Guideline Update for Percutaneous Coronary Intervention for policy on clinical areas not covered by the focused update (13a). Individual recommendations updated in this focused update will be incorporated into future revisions and/or updates of the full-text guidelines."
Modèle de régression linéaire multiple pour prédire la température intérieure sur les bâtiments éducatifs en milieu Méditerranéen

description: Les bâtiments éducatifs existants des dernières décennies suivent généralement un modèle de conception similaire qui néglige l'efficacité énergétique et le confort thermique. Pour répondre aux critères de construction actuels, ces bâtiments sont rénovés, ce qui est moins coûteux qu'une nouvelle construction mais améliore également le confort. Pour évaluer correctement l'efficacité d'une rénovation, il convient d'étudier en profondeur les conditions du bâtiment et le climat intérieur actuel. Des mesures extensives du climat intérieur (température, humidité et CO2) ont été réalisées dans quatre bâtiments scolaires de l'IUT de Nîmes. Dans cet article, le climat intérieur de 31 salles sélectionnées, comprenant des salles de classe, des bureaux et des salles de TP, est analysé en fonction de leur orientation, de leur étage et de leur taille. Il a été constaté que les salles orientées au nord dans au RDC au centre du bâtiment, qui sont les salles de TP, ont la température la plus élevée de 32°C en moyenne (27°C minimum et 36°C maximum). Ces caractéristiques ont ensuite été utilisées pour développer un modèle de régression linéaire multiple pour prédire les températures intérieures en ajoutant cinq autres paramètres tels que la température extérieure (Text), l'humidité extérieure (HRext), l'humidité intérieure (HRin), le CO2 et le rayonnement solaire (RT). Le meilleur modèle qui peut expliquer 74 % de la variance (R2 ajusté =0,74) doit inclure les huit paramètres. Le modèle peut être amélioré si des pièces identiques sont utilisées.

description: Mining frequent itemsets is an essential problem in data mining and plays an important role in many data mining applications. In recent years, some itemset representations based on node sets have been proposed, which have shown to be very efficient for mining frequent itemsets. In this paper, we propose DiffNodeset, a novel and more efficient itemset representation, for mining frequent itemsets. Based on the DiffNodeset structure, we present an efficient algorithm, named dFIN, to mining frequent itemsets. To achieve high efficiency, dFIN finds frequent itemsets using a set-enumeration tree with a hybrid search strategy and directly enumerates frequent itemsets without candidate generation under some case. For evaluating the performance of dFIN, we have conduct extensive experiments to compare it against with existing leading algorithms on a variety of real and synthetic datasets. The experimental results show that dFIN is significantly faster than these leading algorithms.

description: The stability of sand castles is determined by the structure of wet granulates. Experimental data about the size distribution of fluid pockets are ambiguous about their origin. We discovered that contact angle hysteresis plays a fundamental role in the equilibrium distribution of bridge volumes, and not geometrical disorder as commonly conjectured, which has substantial consequences on the mechanical properties of wet granular beds, including a history dependent rheology and lowered strength. Our findings are obtained using a novel model where the Laplace pressures, bridge volumes and contact angles are dynamical variables associated to the contact points. While accounting for contact line pinning, we track the temporal evolution of each bridge. We observe a cross-over to a power-law decay of the variance of capillary pressures at late times and a saturation of the variance of bridge volumes to a finite value connected to contact line pinning. Large scale simulations of liquid transport in the bridge network reveal that the equilibration dynamics at early times is well described by a mean field model. The spread of final bridge volumes can be directly related to the magnitude of contact angle hysteresis.

description: In spite of its problems with interactions, the first-quantized Klein-Gordon equation is a satisfactory theory of free spinless particles. Moreover, the usual theory may be extended to describe Lorentz-violating behavior, of the same types that exist can in second-quantized scalar field theories. However, because the construction of the theory requires a restriction to positive-energy modes, the Hilbert space inner product and the position operator depend explicitly on the form of the Lorentz violation.

description: We report on the spin-Hall magnetoresistance (SMR) and spin Seebeck effect (SSE) in multiferroic CoCr2O4 (CCO) spinel thin films with Pt contacts. We observe a large enhancement of both signals below the spin-spiral (Ts = 28 K) and the spin lock-in transitions (T_{lock_in} = 14 K). The SMR and SSE response in the spin lock-in phase are one order of magnitude larger than those observed at the ferrimagnetic transition temperature (Tc = 94 K), which indicates that the interaction between spins at the Pt|CCO interface is more efficient in the non-collinear magnetic state below Ts and T_{lock-in}. At T > Tc, magnetic field-induced SMR and SSE signals are observed, which can be explained by a high interface susceptibility. Our results show that the spin transport at the Pt|CCO interface is sensitive to the magnetic phases but cannot be explained solely by the bulk magnetization.

description: L’utilisation de sols traités à la chaux et aux liants hydrauliques est de plus en plus privilégiée pour la construction d’ouvrages géotechniques, aussi bien dans une démarche économique qu’environnementale. Afin d’optimiser le dimensionnement de ces ouvrages, une compréhension fine du comportement chemo-mécanique de ces sols est nécessaire, en particulier pour comprendre l’origine du gain mécanique associé à leur traitement. Pour cela, un modèle multi-échelle d’homogénéisation est proposé. Il est basé sur des observations de l’agencement structurel entre les particules de sol et des phases hydratées provenant de la chaux et du ciment ainsi que sur des hypothèses sur la quantité et la nature des hydrates formés. Les résultats numériques ainsi obtenus sont comparés à des mesures expérimentales du module d’Young en laboratoire obtenues avec des cellules piézoélectriques sur des éprouvettes de sol compacté. La comparaison permet de valider les hypothèses du modèle proposé.

Exploring the relationship between women’s empowerment and the internet in China: potentials and constraints
Creators: name: Han, Xiao
Publisher: name: University of Westminster
Year: 2016

description: This thesis reports on an exploratory study of the relationship between the Internet and women’s empowerment in China. The theoretical framework of the study combines feminist theorisations of power – the core concept of empowerment – with insights from sociological perspectives on power and gender, as well as collective action theory. This allows for the conceptualisation of women’s empowerment as a dynamic process that is shaped by a set of communicative practices. Focusing on female Chinese bloggers and women’s groups of different organisational types, this study aims to explore the respective ways in which these two types of women actors use the Internet with a view to examining whether, and the extent to which it enables them to generate a sense of empowerment. The empirical data mainly derives from interviews with female bloggers and with staff members from different women’s groups, as well as from a features analysis and social network analysis of the sampled blogs and official websites of studied groups. Overall, the findings suggest that the opportunities offered by the Internet for women’s empowerment through awareness-raising, social interactions, and the organising of collective action, are limited. For female bloggers, their activities do not translate the new communicative practices afforded by the Internet into concrete action to bring about changes in their everyday life. On the contrary, blogs become an alternative platform to discipline their behaviours and to reinforce patriarchal gendered norms. Moreover, the research finds that the promise of empowerment is further undermined by the pervasive commercialisation of the Internet and state control. For women’s groups, contextual factors prevent them from fully realising the potential of the Internet for increasing their organisational visibility, promoting public awareness about gender issues, building a sense of the collective, campaigning, or networking. The major barriers in these processes are state control, a lack of resources, online censorship, and at times, competition from commercial sites. In this respect, the Internet does not play a significant role in forming a collective to challenge existing unjust power relations.

Tra padri e figli: un rapporto conflittuale… in trasformazione
Creators: name: Cambi, Franco
Publisher: name: Rivista Italiana di Educazione Familiare
Year: 2009

description: La cultura occidentale dall’antichità greco-romana fino a tempi recenti è contrassegnata dal conflitto tra padri e figli, secondo un modello relazionale soltanto di recente delegittimato e in apparenza superato. Il suo posto è stato rilevato da una nuova figura di «padre», che ha deposto ogni autoritarismo, avvicinandosi così al ruolo che prima era esclusivamente materno. Il paradigma di questo nuovo stile di genitorialità è incentrato sulla cura e sul sostegno, ovvero sulla disponibilità a interpretare i bisogni del figlio e a cogliere le richieste di aiuto senza anticiparle. Si tratta di una nuova genitorialità tipica del postmoderno, che ha bisogno, per affermarsi, di forme di accompagnamento, ma che si fonda sulla riscoperta delle profonde radici biologiche della relazione tra padri e figli.

description: A consistent theory of free tachyons has shown how tachyon neutrinos can explain major cosmological phenomena, Dark Energy and Dark Matter. Now we investigate how tachyon neutrinos might interact with other particles: the weak interactions. Using the quantized field operators for electrons and tachyon neutrinos, the simplest interaction shows how the chirality selection rule, put in by force in the Standard Model, comes out naturally. Then I wander into a re-study of what we do with negative frequencies of plane wave solutions of relativistic wave equations. The findings are simple and surprising, leading to a novel understanding of how to construct quantum field theories.

The intersection of racial-ethnic socialization and adolescence: A closer examination at stage-salient issues
Creators: name: Smith, Ruth Katie
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: The literature on parental racial–ethnic socialization (RES) has established the multiple protective effects of RES on developmental outcomes. Although the majority of this literature examines RES processes in adolescence, with the exception of identity processes this literature has not specifically tackled how these messages intersect with specific adolescent developmental processes. We review the literature on RES processes in non‐White adolescents with a focus on the parent–adolescent relationship, risk‐taking behaviors, romantic relationships, and different contexts (i.e., extracurricular, work, and social media settings). We propose that developmental science needs to account for how parental RES may not only change in adolescence, but in particular responds to the perceived risks associated with this developmental period and interacts with normative developmental tasks and milestones.

description: En environnement maritime, les structures en béton armé exposées au marnage sont sujettes à une pénétration rapide des ions chlorure et donc à une corrosion prématurée des armatures. Cette étude propose un modèle de transport basé sur une approche physico-chimique des phénomènes. Ce modèle est décrit, ses hypothèses sont justifiées et il est comparé à des mesures in situ. Sur cette base, une étude de sensibilité basée sur la méthode de Morris est effectuée en mettant en œuvre 100 simulations : ainsi, les influences respectives de 9 paramètres d’entrée sur les temps d’initiation de la corrosion peuvent être comparées. Il en ressort que les paramètres les plus influents sont la concentration critique en chlorure considérée et les facteurs liés à la diffusivité de ces ions. Les paramètres de sorption de l’humidité et de fixation des ions ont des effets notables mais plus modérés. A partir de l’analyse détaillée de ces résultats, on déduit des indications pour une utilisation plus pertinente des modèles de type ingénieur basés sur la 2nde loi de Fick en utilisant des paramètres d’entrée déterministes plutôt que des fonctions de densité de probabilité.

description: La déformation permanente (en particulier l'orniérage) est l'une des défaillances les plus courantes des couches de roulement dans les chaussées, qui compromet sérieusement la qualité du service routier et qui est susceptible d'induire des fissures et d'autres dommages. En se basant sur la méthode des éléments discrets (DEM), nous avons utilisé le logiciel LMGC90 pour réaliser des essais numériques de l’essai de roulement (FWTT : French Wheel Tracking Test) afin de prédire l'évolution de la déformation de surface de deux types de mélanges d'enrobé et d'analyser les réponses micromécaniques de ces mélanges pendant le développement de l'état de déformation. Le modèle se base sur une empreinte de roue à géométrie réelle. Afin de modéliser des mélanges granulaires plus réalistes, nous avons utilisé un pavage de Voronoï avec le logiciel Neper, pour prendre en compte la granulométrie réelle des agrégats. Deux lois de contact viscoélastique (modèle de Burgers et VENoL) ont été utilisées pour modéliser les propriétés mécaniques des granulats et du mastic respectivement. Des simulations numériques de l’essai de roulement ont été réalisés considérant une hypothèse de charge équivalente simplifiée et d'un échantillon à échelle réelle, puis confrontés à des essais en laboratoire. Les résultats montrent que la simulation numérique permet de prédire l'évolution de la déformation de la surface de la plaque d'enrobé. En outre, l'analyse de la réponse micromécanique des mélanges bitumineux, a révélé des chemins privilégiés de transmission du chargement, qui explique les mécanismes de déformation à l’échelle des particules.

description: Due to its transverse nature, spin Hall effects (SHE) provide the possibility to excite and detect spin currents and magnetization dynamics even in magnetic insulators. Magnetic insulators are outstanding materials for the investigation of nonlinear phenomena and for novel low power spintronics applications because of their extremely low Gilbert damping. Here, we report on the direct imaging of electrically driven spin-torque ferromagnetic resonance (ST-FMR) in the ferrimagnetic insulator Y$_3$Fe$_5$O$_{12}$ based on the excitation and detection by SHEs. The driven spin dynamics in Y$_3$Fe$_5$O$_{12}$ is directly imaged by spatially-resolved microfocused Brillouin light scattering (BLS) spectroscopy. Previously, ST-FMR experiments assumed a uniform precession across the sample, which is not valid in our measurements. A strong spin-wave localization in the center of the sample is observed indicating the formation of a nonlinear, self-localized spin-wave `bullet'.
Convergence guarantees for coefficient reconstruction in PDEs from boundary measurements by variational and Newton type methods via range invariance
Creators: name: Kaltenbacher, Barbara
Publisher: name: arXiv
Year: 2022

description: A key observation underlying this paper is the fact that the range invariance condition for convergence of regularization methods for nonlinear ill-posed operator equations -- such as coefficient identification in partial differential equiations (PDE)s from boundary observations -- can often be achieved by extending the seached for parameter in the sense of allowing it to depend on additional variables. This clearly counteracts unique identifiability of the parameter, though. The second key idea of this paper is now to restore the original restricted dependency of the parameter by penalization. This is shown to lead to convergence of variational (Tikhonov type) and iterative (Newton type) regularization methods. We concretize the abstract convergence analysis in a framework typical of parameter identification in PDEs in a reduced and an all-at-once setting. This is further illustrated by three examples of coefficient identification from boundary observations in elliptic and time-dependent PDEs.

Il genitore riflessivo. La costruzione narrativa del sapere e delle pratiche genitoriali
Creators: name: Fabbri, Loretta
Publisher: name: Rivista Italiana di Educazione Familiare
Year: 2009

description: Il saggio muove dalla premessa secondo cui la cultura familiare include saperi impliciti ed espliciti che si trasformano e si sviluppano tramite l’esperienza. Gli apprendimenti genitoriali si traducono in prospettive determinate, che rimangono per lo più inconsce e dunque possono contenere elementi di distorsione. Il riconoscimento di tale processo consente l’adozione di un approccio riflessivo alla genitorialità capace di rendere i genitori costruttori attivi delle proprie conoscenze e competenze e interpreti consapevoli delle proprie esperienze. Nell’attuale contesto di disorientamento della famiglia, per sostenere i genitori in questo impegno può essere utile una formazione specifica finalizzata a sviluppare un adeguato pensiero critico.

description: Evidence exists that service quality delivery through Web sites is an essential strategy to success, possibly more important than low price and Web presence. To deliver superior service quality, managers of companies with Web presences must first understand how customers perceive and evaluate online customer service. Information on this topic is beginning to emerge from both academic and practitioner sources, but this information has not yet been examined as a whole. The goals of this article are to review and synthesize the literature about service quality delivery through Web sites, describe what is known about the topic, and develop an agenda for needed research.

description: A multimode optical fiber with a truncated transverse cross section acts as a powerful versatile support to investigate the wave features of complex ray dynamics. In this paper, we concentrate on the case of a geometry inducing a mixed dynamics. We highlight the properties of regular modes associated to stable periodic orbits such as an enhanced intensity localization and report unexpected attributes such as the statistics of the Inverse Participation Ratio that present features analogous to those of Anderson localized modes. Our study is supported by both numerical and experimental results.

Stratégies de modélisation discrète d’un mur maçonné sollicité en cisaillement : vers une prise en compte de l’endommagement des blocs
Creators: name: Boukham, Ali
Publisher: name: Academic Journal of Civil Engineering

description: Les structures maçonnées représentent une grande partie du patrimoine bâti français et mondial. La préservation de ces édifices nécessite de recourir à une démarche de diagnostic multidisciplinaire comprenant une étape d’évaluation structurale afin d’estimer leur état de stabilité. Cependant, cette tache reste délicate du fait de la forte non linéarité du matériau maçonnerie et de la complexité des géométries de ce type d’ouvrage. Pour cela, plusieurs stratégies de modélisation robustes ont été développées. Parmi ces stratégies, les modèles bloc à bloc basés sur la méthode des éléments discrets et plus spécifiquement la NSCD (Non Smooth Contact Dynamics) permettent de tenir compte de l’appareillage réel des maçonneries. Néanmoins, dans ce type d’approche, les blocs sont élastiques et les non linéarité apparaissent uniquement au niveau des interfaces entre blocs régies par des lois cohésives frictionnelles. Dans cette étude, l’utilisation d’une nouvelle approche dite hybride est proposée. Elle consiste à intégrer un modèle couplant endommagement et plasticité dans les blocs éléments finis. La validation de cette approche numérique est réalisée sur la base d’une campagne expérimentale sur murs en maçonnerie testés en cisaillement et soumis à une charge verticale.

description: In France, embodied carbon represents 35% [1] of the total green house gases emissions from the construction sector. This proportion can reach up to 70% when considering recent buildings [2]. Diminishing environmental impacts of building’s construction and demolition prove to be necessary to reach European environmental agreements. In particular, structural elements account for a large portion of material quantity and environmental impacts [3]. This article assesses building structures impacts in order to determine the importance of early stage decisions for the construction of housing and office buildings. To study the influence of materials, span and grid choices on the structure environmental impact, it combines the INIES database (French Environmental Product Declaration database) and parametric buildings built with a set of precalculated structural elements composed of beams, columns, floor systems and foundations. Using Life Cycle Assesment (LCA) provides a more comprehensive picture of environmental impacts, expanding common energy analysis. Results are mostly influenced by structural typology and materials, and to a lesser extent by grid choices and span. Structural solutions can also better perform for a particular indicator while presenting higher impacts for another. It proves the necessity for designers to carry out holistic analysis.
