La recherche de légitimité par la conformité aux codes de gouvernance d'entreprise. Une analyse des déclarations de conformité des sociétés françaises du SBF 120
Authors: Refait-Alexandre Catherine , Duhamel Jean-Christophe , Fasterling Bjorn
Published: July 2014

Cet article analyse la façon dont les sociétés du SBF 120 mettent en œuvre l’obligation du comply or explain, introduite en droit français en 2008. Nos principales conclusions sont les suivantes : la délivrance de déclarations claires et sans ambigüité, ainsi que la conformité au code de gouvernance de référence sont liées à certaines caractéristiques d’entreprise (secteur d’activité, structure de l’actionnariat, taille). Ces résultats peuvent donner lieu à l’interprétation suivante : le principe de comply or explain est un outil pouvant être utilisé par les entreprises pour communiquer avec leurs partenaires, notamment sur les marchés financiers, plus qu’un instrument réglementaire pouvant discipliner les comportements managériaux.
Affichages responsables et préférence des consommateurs : quel rôle pour la marque ?
Authors: Akli Achabou Mohamed
Published: July 2014

Nous nous sommes interrogés dans cet article sur la pertinence du choix stratégique de Nespresso d’opter pour une auto-déclaration dans un contexte de scepticisme croissant des consommateurs envers les affichages responsables, particulièrement ceux établis par les entreprises. Pour atteindre cet objectif, une étude empirique a été conduite auprès de 134 consommateurs français. Les résultats d’une analyse conjointe montrent que l’affichage responsable établi par Nespresso est favorablement perçu par les consommateurs et influence positivement leur préférence avec un même degré d’importance que la certification indépendante Fairtrade. Les consommateurs semblent faire confiance à la marque et pensent qu’elle ne prendrait pas le risque d’afficher de fausses informations au risque de nuire à sa réputation.
Les obstacles à l'innovation en France : analyse et recommandations
Authors: dos Santos Paulino Victor , Tahri Najoua
Published: July 2014

Cet article a pour objet d’étudier les obstacles à l’innovation en France à la lumière des caractéristiques des processus d’innovation et du contexte interne et externe. Nous montrons que les principaux obstacles à l’innovation sont non-technologiques. Nous interprétons ce résultat par la difficulté des entreprises à combiner les compétences techniques et les compétences commerciales dans les processus d’innovation. Pour lever ces obstacles non-technologiques, nous considérons qu’il faut donner plus de poids aux compétences commerciales dans les processus d’innovation.

Comportements de cession de biens durables d'occasion : une étude appliquée à la revente automobile en CtoC
Authors: Prieto Marc , Dutertre Emmanuelle
Published: July 2014

L’importance des pratiques de cession de produits d’occasion, dont une large part s’effectue entre consommateurs (CtoC), contraste avec le faible nombre de travaux académiques en marketing portant sur cette question. L’article vise à établir le profil de ces revendeurs à travers le cas de l’automobile d’occasion en France. À partir d’une enquête menée auprès de 517 revendeurs particuliers, une taxonomie fondée sur les motivations de ces revendeurs, permet de définir les profils qui pourraient bénéficier de services d’accompagnement par des professionnels. Les résultats indiquent également un cloisonnement entre le canal de revente en CtoC et les réseaux d’occasion intermédiés ainsi qu’un relatif manque d’expérience des revendeurs particuliers.
Valorisation territoriale, sociétale et environnementale : le cas de la Bande verte et citoyenne
Authors: Callot Philippe , Selosse Antoine
Published: July 2014

Après avoir créé et ouvert un grand parcours européen sur les pas de saint Martin la « Via Sancti Martini » , reliant la ville natale de saint Martin (Szombathely/Vas) en Hongrie à la ville de sa mort (Candes Saint-Martin/ Indre-et-Loire) en France, le Centre Culturel Européen (CCE) saint Martin de Tours travaille aujourd’hui à son développement dans une perspective d’aménagement du territoire et de développement durable. Pour ce faire, le CCE développe actuellement le concept d’une Bande verte et citoyenne de 2 000 km de long et 20 km de large valorisant un tourisme lent et de citoyenneté. Ce concept s’appuie sur la valeur du « Partage citoyen ». L’article met en évidence le rôle majeur de parties prenantes contractuelles en faveur de celles qualifiées de non-contractuelles. Pour la valorisation de ce projet le CCE doit désormais s’appuyer sur des prestataires de services composant ainsi un triptyque de parties prenantes aux motivations radicalement différentes.

Quelle politique kurde pour l'AKP ?
Authors: Benhaim Yohanan
Published: July 2014

L’émergence d’un Kurdistan irakien autonome, la guerre civile syrienne et les ambitions électorales de l’AKP se conjuguent pour déboucher sur une nouvelle politique du gouvernement turc concernant la problématique kurde. Mais à l’heure où les zones kurdes s’articulent entre elles dans des processus transfrontaliers entre Turquie, Irak et Syrie, l’AKP devra choisir entre la frange nationaliste de son électorat et la poursuite du rapprochement avec les Kurdes du Sud-Est turc. politique étrangère
Les paradoxes du printemps kurde en Syrie
Authors: Tejel Jordi
Published: July 2014

Très minoritaires dans le pays et très divisés, les Kurdes de Syrie ont néanmoins pu gagner, à la faveur de la guerre civile, une relative autonomie dans leur espace du Nord. Les complexes recompositions régionales, les incessantes rivalités entre partis kurdes n’empêchent pas un relatif rapprochement entre les divers espaces kurdes, éclatés entre Turquie, Syrie, Irak. Mais la question kurde demeure marginalisée dans les processus politiques qui tentent de mettre fin au conflit syrien. politique étrangère
L'introuvable frontière du Kurdistan d'Irak
Authors: Roussel Cyril
Published: July 2014

Depuis 1991, les partis kurdes dominent et administrent le « Kurdistan irakien ». Cette autonomie pose à Bagdad de multiples problèmes, dont celui du partage des rôles pour l’exploitation et la commercialisation pétrolières. Surtout, les limites de ce Kurdistan, géré comme un État, sont incertaines. Dans les espaces contestés s’opposent les logiques communautaires et les découpages administratifs : les frontières militaires, administratives, de fait et de droit, ne correspondent pas. politique étrangère
Le conflit ukraino-russe vu de Kiev

Moscou entend à toute force accrocher l’Ukraine à son Union eurasiatique, avec une carte majeure : celle de l’échange de la souveraineté de Kiev contre des avantages économiques et financiers. Au-delà de l’affaire de la Crimée, c’est bien désormais l’intégrité même du pays qui est en cause, ainsi que l’ensemble de l’équilibre européen. Un dialogue reste encore possible, mais il suppose d’abord que la Russie soit mise hors d’état d’imposer unilatéralement sa volonté à l’Ukraine. politique étrangère
La crise ukrainienne ou le malentendu européen
Authors: Lefort Philippe
Published: July 2014

La crise ukrainienne semble avant tout résulter du choc de deux malentendus sur les représentations russes et occidentales. Mais elle est aussi le produit d’un déficit de communication entre Moscou et l’Occident, notamment l’UE, particulièrement depuis le conflit géorgien de 2008. Le réengagement du dialogue entre les acteurs passe par la prise de conscience réciproque des spécificités historiques et culturelles de chacun. politique étrangère
Le lancinant problème de l'insolvabilité des États
Authors: Gaillard Norbert
Published: July 2014

Historiquement, les États se sont endettés pour financer des campagnes militaires. Ils le font désormais pour d’autres motifs, comme le financement d’investissements productifs. L’État n’est pas un débiteur comme les autres : en cas de défaut de paiement, ses créanciers peuvent avoir le plus grand mal à récupérer leurs fonds. La mesure du risque souverain est donc un enjeu crucial qui requiert une expertise à la fois politique, économique et financière. politique étrangère
La paix comme but de guerre : une lente redécouverte

Dans la traditionnelle conception de la guerre juste, le conflit armé doit déboucher sur les conditions d’une paix durable. Après un xix e  siècle valorisant la pure victoire sur le champ de bataille, le xx e  siècle redécouvre, en particulier du fait de l’atome, la dimension politique de la guerre. C’est à partir de cette prise de conscience que les États d’aujourd’hui – et en particulier les membres de l’Union européenne – pourront élaborer les conditions d’une « sécurité durable ». politique étrangère

Authors: Cardinal Jacqueline
Published: July 2014

Pierre Jeanniot a été président et chef de la direction d’Air Canada de 1984 à 1990. D’abord simple technicien, il a gravi les échelons jusqu’à devenir président. On lui doit la conception de la boîte noire, telle qu’on la connaît aujourd’hui. Contre vents et marées, il a privatisé le transporteur aérien national après y avoir opéré un redressement spectaculaire. Il a ensuite dirigé la prestigieuse Association internationale du transport aérien (IATA) de 1993 à 2002, transformant le groupe de pression bureaucratique en un organisme influent et incontournable à l’échelle internationale. En reconnaissance de sa contribution exceptionnelle, l’IATA lui a octroyé le titre de directeur général émérite. Il est aujourd’hui président-directeur général de Jinmag inc., une société-conseil en gestion. Il est administrateur de sociétés et un conférencier recherché pour ses vues sur les enjeux actuels et futurs auxquels l’industrie aérienne fait face. Comment ce Montréalais d’adoption, arrivé sans le sou à Montréal avec sa mère à l’âge de 14 ans, a-t-il pu atteindre de tels sommets ?

Authors: Barès Franck , Sylvain Renaud
Published: July 2014

On observe une nouvelle tendance dans les écoles de gestion telles que HEC Montréal, soit la volonté manifestée par des étudiants d’inscrire leurs premières expériences professionnelles dans le champ de l’accompagnement entrepreneurial. Désireux de vivre de l’intérieur les missions de l’entrepreneur et d’expérimenter les enjeux des phases de création et de démarrage, ces derniers recherchent l’occasion de relever des défis variés. Devant ce phénomène grandissant, une question se pose : en quoi un stage dans une jeune entreprise peut-il correspondre aux défis que des étudiants en fin de parcours universitaire souhaitent relever ? Cet article présente six défis propres à la réalisation d’un mandat d’accompagnement pouvant ouvrir sur des occasions d’apprentissage et de développement professionnel, défis découverts à la suite d’une expérience d’immersion au sein d’une entreprise en démarrage, vécue par un étudiant de HEC Montréal. L’objectif poursuivi est que la possibilité de vivre de tels mandats soit bénéfique pour les entrepreneurs accompagnés et plus facilement accessible aux étudiants. Des pistes de réflexion sur le rôle d’orientation et d’encadrement de l’université pour ces stages sont également proposées.
Travailler n'importe où, n'importe quand ? Pas si sûr...

Published: July 2014

S’il est aujourd’hui possible de travailler n’importe où, n’importe quand, grâce aux technologies mobiles, cette recherche qualitative menée auprès d’une vingtaine de cadres et de professionnels québécois montre que ces derniers ont des attitudes ambivalentes en la matière. En effet, d’un côté, ils sont soucieux de ne pas laisser le travail envahir leur vie personnelle; d’un autre côté, ils aimeraient profiter pleinement de la flexibilité offerte par les technologies mobiles, mais celle-ci n’est pas toujours permise par l’organisation du travail.
Les modèles d'affaires à l'ère d'internet et de la numérisation : six pistes d'action pour favoriser la performance d'une entreprise
Authors: Bissonnette Joëlle , Brunelle Éric
Published: July 2014

Internet et la numérisation bouleversent les façons de faire dans de nombreuses industries, ce qui est source à la fois de crises et de nouvelles possibilités. Dans les industries de la culture et de l’information, même s’il ne s’est jamais écouté, lu, vu et utilisé autant de musique, de livres, de films, de logiciels et d’autres biens culturels et informationnels, il est extrêmement difficile pour les entreprises qui y œuvrent d’atteindre la rentabilité. En contrepartie, au sein de ces industries, des entreprises prennent des initiatives originales en vue de s’adapter à ces phénomènes technologiques et d’en tirer profit. S’inspirant des pratiques adoptées par ces entreprises innovantes, cet article fait état de six pistes d’action susceptibles de favoriser la performance des modèles d’affaires à l’ère d’Internet et de la numérisation. Il présente des exemples concrets de la façon dont se déploient ces pistes d’action, exemples puisés dans des entreprises des industries de la culture et de l’information, particulièrement touchées par ces phénomènes technologiques. Ces pistes peuvent donc être un outil précieux pour les praticiens de toutes les industries qui cherchent à adapter leur modèle d’affaires à Internet et à la numérisation.

Published: July 2014

Les banques françaises, dans le cadre de leur stratégie multicanal, ont développé des interfaces permettant de créer de nouvelles relations avec leurs clients. La stratégie d’individualisation transforme l’internaute en client-collaborateur et la stratégie communautaire met en lumière la nouvelle place du client-acteur dans la communication des entreprises bancaires françaises. Les différentes formes de communication numérique, individualisée ou communautaire, loin d’être opposées, peuvent constituer une source d’opportunités si des relations de confiance sont établies.
Les institutions financières coopératives : réinventer la promesse client
Authors: Coupet André
Published: July 2014

Les grandes institutions financières coopératives ou mutuelles, canadiennes comme françaises, ont tendance à se banaliser. Leur gouvernance, très complexe, et leur engagement, pourtant significatif dans la société, n’alimentent plus leur capital de marque; la valeur perçue par leurs clients-sociétaires se fixe sur un service de base, en l’occurrence passable, et surtout non différencié, sans valeur ajoutée. Il incombe donc à ces institutions, en tout premier lieu, de réinventer leur promesse client en puisant dans leurs valeurs d’origine : l’accessibilité, la solidarité entre sociétaires et la responsabilisation de leurs clients, notamment par l’éducation et par la pédagogie de l’argent et des risques.

Bar Diameter Is an Important Component of Knee-Spanning External Fixator Stiffness and Cost
Authors: Kim Hyunchul , Russell Joseph P. , Hsieh Adam H. , O’Toole Robert V.
Published: July 2014

The authors’ objective was to determine the effects of bar diameter on the stiffness and cost of a knee-spanning external fixator. The authors studied 2 versions of an external fixator with a difference in bar diameter (small bars, 8-mm diameter; large bars, 11-mm diameter). Fixators were tested using frame dimensions and a synthetic fracture model appropriate for a tibial plateau fracture. Five configurations of each fixator were tested: standard, cross-link, oblique pin, double stack, and super construct. The construct stiffness of each configuration (n=60) was measured in anterior-posterior bending, medial-lateral bending, axial torsion, and axial compression. Cost analysis allowed for calculation of the stiffness per unit cost. In the large bar group, an increase in construct stiffness was noted for all constructs and testing modes. Magnitude of stiffness increase ranged from 24% to 224% (
P
<.05 in all cases), depending on the configuration and loading mode. Increase in stiffness was so large that double-stack small bars performed similarly to standard construct large bars. Considering that the frame components have similar costs, the double-stack small bar fixator results in a 66% increase in cost for the same stiffness provided by the standard large bar. Bar diameter seems to have a large effect on knee-spanning external fixators. The authors observed an increase in stiffness of up to 191% under anterior-posterior bending despite an increase in bar size of only 37.5%. This finding might allow clinicians to use less expensive frames constructed of larger bars without sacrificing construct stiffness.
Reproducibility of Femoral Offset Following Short Stem and Straight Stem Total Hip Arthroplasty
Authors: von Roth Philipp , Perka Carsten , Mayr Hermann O. , Preininger Bernd , Ziebula Friedrich , Matziolis Georg , Hube Robert
Published: July 2014

Bone stock–preserving short stem prostheses have gained importance in total hip arthroplasty (THA) with the use of minimally invasive surgical procedures. Because of their metaphyseal fixation and their dependency on the calcar radius, it is unknown whether the femoral offset can be reproduced with the same accuracy following short stem vs standard stem THA. This study clarifies whether it is possible to restore the femoral offset using a short stem prosthesis (Fitmore; Zimmer, Warsaw, Indiana) compared with a conventional straight stem prosthesis (CLS; Zimmer) following minimally invasive implantation using an anterolateral approach. In a prospective, randomized, double-blinded study, 80 patients underwent THA using a short stem (SS group; n=40) or CLS implant (control group; n=40). Follow-up examinations were conducted 6 weeks postoperatively. Radiological and functional outcomes were measured. Subjective assessment of quality of life was evaluated using the Harris Hip Score (HHS), the Short Form 36-item health survey (SF-36), and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Pre- and postoperative comparison of the groups’ change in offset showed no significant differences (SS group difference from pre- to postoperative, 6.1±6.5 mm; control group difference from pre- to postoperative, 6.5±7.1 mm;
P
=.93). Group comparison after 6 weeks revealed no significant differences in HHS, SF-36, or WOMAC. Based on these data, an equivalent reproducibility of the femoral offset was demonstrated following short stem and straight stem THA using a minimally invasive anterolateral approach. If the long-term results of short stems show a comparable survival, they represent a sensible alternative to standard stems.

Published: July 2014

Numerous studies have revealed the presence of T helper 17 (Th17) cells in pathologic intervertebral disk (IVD) tissues and the contribution of Th17-associated cytokines to the development of this disease. However, the pre- and postoperative changes in the proportion of Th17 cells and the concentration of IL-17 in the peripheral blood of patients with IVD degeneration are not clear. The levels of Th17 frequency and the interleukin-17 (IL-17) concentration in peripheral blood from patients and volunteers were examined by flow cytometry and by enzyme-linked immunosorbent assay (ELISA), respectively. The clinical results were evaluated using the visual analogue scale (VAS). These results were subjected to a correlation analysis. Compared with the normal controls, the proportion of Th17 cells and the concentration of IL-17 were significantly increased preoperatively in patients with IVD degeneration. Postoperatively, the levels of Th17 cells and the expression of IL-17 were dramatically decreased. The correlation analysis of the VAS pain scores, Th17 cell frequency, and IL-17 concentration, including the pre- and postoperative levels and the changes induced by the surgery, revealed a positive correlation. The authors’ results explain the contribution of Th17 cells and IL-17 to the pain sensation experienced by patients with IVD degeneration. These 2 factors may be good indicators for the evaluation of the surgical outcome of patients with lumbar disk herniation.

Damage Identification of the Arch Bridge Based on the Difference of Deflection with Moving Load
Authors: Zhao Zhan , Nie Zhen Hua , Ma Hong Wei
Published: July 2014

A new damage identification method for arch bridge structures under a moving load based on the difference of deflection is presented. The function of the deflection at the mid span of the arch with the changing positions of the moving load is derived using the Moore integral method. It can be concluded from the results that when the moving load is in the area without damage, this target indicates to be linear functions with the cosine of an angle (θ) between moving load and horizontal. Nevertheless, this target is multinomial with the change of cosθ in the damage area. In order to validate the proposed damage detection algorithm, a steel arch modal is simulated, which is proved to be practicable in projects. The results indicate that the location and degree of single damage can be identified accurately.

Published: July 2014

This paper states the comparison research of calculation results from program LSSRLI-1 and program SHAKE2000, with the strong seismic records as well as the site soil conditions by using borehole arrays. The analytical results show that the site soil conditions have an amplification effect on the seismic PGA and response spectrum values, however, the actual seismic records are not consistent with the program calculations on the amplification effect. Besides, the site soil conditions also have an altering effect on the predominant period of seismic response spectrum, where actual seismic records and program calculation results of the altering effect are not the same either.

On this basis, the aeolian sand cohesion and internal friction angle were measured by the quick direct shear test when aeolian sand was at the optimum moisture content and near the most largest compactness. And the bearing capacity of retaining wall model which regarded aeolian sand as fillers was determined. Then bearing capacity change of aeolian sand wrapped before and after was compared. Experimental results showed that: when the aeolian sand was in the wet and compacted state, its cohesion was 3.31 kPa and internal friction angle was 36.8°. The aeolian sand bearing capacity was 153.8kPa by the plate loading test. The aeolian sand wrapped with a geotextile bearing capacity was 194.1kPa. Through the aeolian sand research of Baotou area, it provides a useful reference for the construction of highway and railway and application of wrap-reinforced retaining wall which is a new retaining structure in the region, and the aeolian sand is treated as a special filling material in these structures.
The Application of Cubic Spline Interpolation Function in Determining Rock Rheological Long-Term Strength
Authors: Zhao Mo Li , Zhang Qiang Yong
Published: July 2014

The rheological long-term strength is determined according to the triaxial rheological test data of diabase at the dam area of Dagangshan Hydropower Station. Firstly, based on the stress-strain isochronous curve method and connected the test points with cubic spline interpolation function, the maximum deviation point in the long-term interval is determined as the turning point and established the long-term strength by nonlinear least square method. The results show that this method is consistent with the other methods. Finally, the advantage and disadvantage of this method is analyzed. This method can overcome the randomness of artificial selecting the turning points. Therefore, maximum deviation point method is relatively a reasonable and effective method to determine the rheological long-term strength of rock.

The pregnant and sliding mechanism was firstly compared between Vajont and Qianjiangping large rock landslides, which happened in the chair-shaped cataclinal bank slopes. And then the essence of the landslides occurred was deduced. The pregnant and sliding process of the landslides was showed two stages. First, after the first impoundment of the reservoir, the soil and shallow rock at the front of the landslides were slipped and then caused posterior margin of the deep latent sliding surface cracks. So the groundwater supply condition was significantly changed. Second, with the rapidly increase of the groundwater recharge, its pressure on the front of the landslides was also rapidly rise to the critical value which the landslides occurred. Afterwards, the stability mechanical model of the chair-shaped cataclinal bank slopes and critical value formula of the groundwater pressure were established on the basis of the stability mechanical model of general chair-shaped cataclinal slopes, added reservoir water level which was a dynamic load. While working procedures to determine the groundwater pressure was put forward. Last, the theory was certified validity take Liangshuijing rock landslide of the Three Gorges Project area as an example and the monitoring methods and control measures for the landslide were proposed.

Study of Key Parameters in the Process of Aeolian Sand Compactibility
Authors: Yin Ying Zi , Wang Ya Lei
Published: July 2014

The main factors affecting soil compatibility include moisture content, compaction work, soil type, grading and coarse material content etc.. The effects of compaction work are as follows: the stronger compaction work is, the more larger soil dry density is. The optimum moisture content decreases with the compaction work increasing. This paper mainly studies the effect of compaction work to aeolian sand compatibility. Its lay-down thickness is about 30-50cm when we use vibratory roller to compact aeolian sand in practical engineering. This paper analysis’s and studies the maximum dry density and the optimum moisture content of aeolian sand in the middle region of Inner Mongolia, and achieves its lay-down thicknesses are 30cm,40cm,and 50cm respectively at the optimum moisture content. We use 85kg vibration-impact rammer instead of YZ 18 vibratory roller to simulate the aeolian sand compaction effect at the optimum moisture content. The specification does not specify the number of compatibility times, but it is generally 3 to 5 times in the actual project .We choose the most suitable compatibility times and lay-down thickness through anglicizing the Aeolian sand compactness for vibration-impact rammer rolling on eloign sand 3 times,4 times, and 5 times respectively at 3 different kinds of lay-down thicknesses. Through the study of the Inner Mongolia area Aeolian sand, it provides a useful reference for highway and railway construction in the desert area as well as the encapsulated layer thickness of reinforced retaining wall, a new type support structure.

Effects of the radius of groove and angle of alloy steel-made cooling slope on the microstructure of hypoeutectic high chromium cast iron after holding at the semisolid state have been investigated. The molten alloy with 1390 °C superheat was poured on the surface of the cooling slope in various radius of groove (100 and 400 mm) and angles (15, 30 and 45°), at constant length and preheating temperature. It was found that cooling slope obviously effects on the microstructure of the alloy. Furthermore, it was also found that the radius of groove and angle of cooling slope affect the size and morphology of the alloy. The results indicate that the minimum grain size of 26μm and maximum shape factor of 0.78 of primary austenite phase was obtained at radius of groove 400 mm and an angle of 30°angle, at a constant pouring temperature, length and preheating temperature.

Authors: Shan Liang , Zhang Liang
Published: July 2014

The mechanical tests of normal concrete (NC) specimens, steel fiber reinforced concrete (SFRC) specimens and polypropylene fiber reinforced concrete (PPFRC) specimens have been carried out. Fiber-reinforced concretes containing different volume fraction and aspect ratio of steel and polypropylene fibers were compared in terms of compressive, splitting tensile, ultimate tensile properties. Test results indicate that the mechanical properties of NC can be improved by addition of steel fibers and can be enhanced with the increase of fiber content. However, polypropylene fiber may cause opposite effect, if volume fraction too high.

Published: July 2014

Replacement rate is an important factor that affects the mechanical properties of recycled concrete. In order to study the influence of replacement rate on triaxial mechanical performance of recycled concrete, 20 recycled concrete cylinder specimens for conventional triaxial loading test with recycled aggregate replacement rate as changing parameters were designed. The results show that replacement rate has a great influence on peak stress of recycled concrete specimens under uniaxial stress, but the effects of replacement rate gradually decreased with the increase of lateral confining pressure. The influence of replacement rate on peak strain is larger than peak stress, the impact of replacement rate on peak strain gradually decreased with the increase of lateral confining pressure. The elastic modulus of recycled concrete specimens changes with different replacement rate, and the fluctuations is in the range of 20%. The results will provide reference for further theoretical study of recycled concrete.
