Comparative analysis of the results of the calculation of the frame node in the IDEA STATICA СCONNECTION software and according to the methods of normative documents
Authors: Pyskunov Serhii , Mitsyuk Serhii , Andriievskyi Viktor , Mitsyuk Dmytro
Published: February 2023

The development of modern construction increases the requirements for the reliability and accuracy of determining the stress-strain state of structures, nodes and details of designed objects. At the same time, today it is difficult to imagine the calculation of any structure without the use of modern software. When calculating the building as a whole, all joints, abutments and connections, as a rule, are specified in a simplified manner. At the same time, the special attention should be paid to the calculation of nodes connecting structures to each other, since, depending on the operating conditions of the node, a different distribution of the stress-strain state is possible, which in turn affects the geometric characteristics and operation of the structures. Thus, the calculation scheme of the node should reflect its real behavior as part of the structure, which, in turn, can lead to the complication of model creation, significant time costs and errors in calculations. Models of materials and individual components (bolts, welds) should also match the real ones as much as possible. This process is most relevant in the design of nodes of metal structures. The design of typical nodes is carried out using serial solutions, standard methods and manuals, but in the case of non-standard nodes of a complex shape, it is advisable to use the component method of finite elements reflected in foreign literature. This approach is implemented in the Idea StatiCa software complex. The model made in this program gives the modern engineer a sufficient amount of information about the behavior of the unit, its stress-strain state and the coefficients of use of individual components, as well as about the results of joint inspections. The results obtained during the calculation of the frame unit using this complex were compared with the calculations performed manually according to the methods of various regulatory documents.
Nonlinear dynamic analisys of reservoir shell with modelled shape imperfections
Authors: Lukianchenko Olha , Gerashchenko Oleh , Paliy Oksana
Published: February 2023

The nonlinear dynamic analysis of imperfect reservoir shell with a variable thickness of wall under pressure was executed. The finite-element model of reservoir in the form of a cylindrical shell in the software NASTRAN was built. The shell wall in the form of the three-cornered finite-element net was presented. Shape imperfection as a lower buckling form of perfect shell (Buckling) was modelled. Value of amplitude of imperfection was set proportionally to a minimum thickness of shell wall. The limits on the radial and tangential displacements of top edge nodes were entered, the nodes of lower edge were fastened. Excitation as external pressure, which linearly depended on  time  and  uniform distributed on all shell elements was presented. The modal analysis of shell  with modelled shape imperfections by using computational procedure of task on natural vibrations (Normal Modes) by the Lanczos method was executed. The nonlinear dynamic analysis (Nonlinear Direct Transient) of imperfect reservoir shell under pressure by N’yumark method was executed. Influence of amplitude of modelled imperfection on the shell stress-strain for different time intervals of excitation, the conditionally critical values of dynamic loading and corresponding of shell deformation forms were investigated.
It was discovered that a modelled shell shape imperfection as a lower buckling form of perfect shell under static pressure in the dynamic analysis of shell under the same type of the loading was effeсtive. Influence of modelled shape imperfections amplitude on the stress-strain state of shell for different time interval of excitation, the conditionally critical values of dynamic loading and appropriate forms of shell deformation was considerable. Presented imperfection model in the modal analysis of shell was not effective. The increase of amplitude of shell imperfection led to insignificant decrease of natural frequencies and amplitudes of appropriate natural forms with the same amount of the semiwaves in the circular direction. In our opinion presented model of shell shape imperfection can be effective in the modal analysis of shell with the stress-strain state from the previous action of static pressure and for the estimation of design reliability of reservoir shell in the case of the dynamic loadings using the Bolotin probabilistic approach.
The stability of elastic elements in a deformed state with initial structural form imperfections for truss elements with rigid nodes was studied
Authors: Bilyk Serhii , Bilyk Artem , Tsyupyn Evhen
Published: February 2023

Abstract. Goal.The stability of elastic elements in a deformed state with initial imperfections of the structural form for truss elements with rigid and elastic nodes was studied. Method. The operation of compressed elastic elements of trusses with rigid welded joints is most accurately described by a model in which one support is rigid and the other has elastic resistance conditions. According to the methodology of the initial parameters, the analytical method from the solution of the differential equation of rod stability, a system of algebraic equations was obtained, which describes the stability of an elastic rod with initial imperfections and deviations. The results. Numerical studies of the deformed state of the elastic rod at various initial imperfections and deviations, force impact parameters, and support elasticity parameters were carried out. The impact on the deformed state of the elastic rod of the displacement of the supports, and the initial imperfections - angle of rotation of the support, as well as different stiffness characteristics of the elastic support, were studied. Numerical studies of the influence of the loading factor on the deformed state of the elastic rod have been carried out. The non-linear nature of the growth of calculated bending moments and maximum rod deflections has been established. In the case of longitudinal bending, the growth of the maximum bending moments when adopting the rod model occurs faster than the increase in the maximum deflections. Regularities between the deformed axis of the rod and the loading factor at different initial deviations of the rigid support are established. The developed and improved methodological approach makes it possible to determine the deformation state of centrally compressed rods with maximum deviations, obtained during the construction, installation, or operation of the structure.Scientific novelty. On the basis of generalized theoretical studies of the deformed state of a centrally compressed elastic rod, taking into account the initial imperfections and conducted numerical studies, the method of identifying regularities between the load-bearing capacity of the rod and the influence of maximum initial imperfections, Metod has been improved. Practical significance. The obtained results and the developed methodology make it possible to clarify the stress-strain state of elastic elements of trusses with rigid nodes, taking into account the revealed imperfections of the various initial imperfections and deviations, force impact parameters, and elasticity parameters supports.
Influence of material functional heterogeneity on non-stationar oscillations of piezoceramic bodies
Authors: Hryhorieva Ludmila , Yanchevskyi Ihor
Published: February 2023

The influence of material functional heterogeneity on mechanical oscillations of piezoelement under non-stationary electrical loading is investigated. Within the assumption of functional distribution of material characteristics by thickness of the piezoelectric element, which corresponds to the physical properties of the body, a unified system of solving equations was obtained to describe the thickness fluctuations of piezoelectric plates, cylinders, and balls. For controllingof accuracy, the calculation is carried out using an explicit and implicit difference scheme.

Unsteady oscillations of a flat piezoceramic layer, cylinder, and sphere are investigated with a parabolic distribution of all material characteristics along the thickness of the element. It is assumed that the average value of the function along the thickness is equal to the tabular value of the material characteristic, and the value on electrodes is proportional to the area of electrodes. At such conditions, we obtained a decrease in the speed of disturbances propagation and a slight change in the amplitude associated with the curvature of the element. The increase in amplitude reaches 3% for balls. It should be noted that at given load oscillations occur in the compressed zone without entering the undeformed state. The considered cylinder and ball have a rather large curvature, for bodies with a smaller curvature the influence of the described effect will be smaller. The additional analysis indicates that the shape of the distribution curve under described above conditions also has little effect on the results.

It was established that the effect of functional heterogeneity within the same material has little effect on the oscillations of the piezoelement, that is, it is really possible to average the material characteristics by thickness at calculating, since the deviation between the results is within acceptable limits (up to 2.5%). Also, an important result is the confirmation of the assumption that for curved bodies such as cylinder and sphere, the material characteristics can be considered constant on thickness, regardless of the curvature of the body.

The proposed technique can be applied for studyingof the vibrations of different geometries bodies with significantly heterogeneous functional material or what are combined from several materials with a gradient transition between them.
Theoretical modelling of the effect of thermal delamination of an asphalt concrete pavement from a rigid foundation of a road or bridge
Authors: Gaidaichuk Viktor , Shlyun Nataliia , Shevchuk Liudmyla , Bilobrytska Olena
Published: February 2023

In the practice of road construction, one of the most common phenomena accompanied by delamination, subsequent cracking and destruction of the asphalt concrete pavement on a rigid (cement concrete or metal) base of a road or bridge is the effect of concentration of shear thermal stresses between the pavement and the base in the edge zones of the structure. They are caused by the fact that, as a rule, the coefficients of linear thermal expansion of the phases of the system have different values, which contributes to the occurrence of incompatible shrinkages and expansions in them. Under conditions of frequent temperature changes in heterogeneous asphalt concrete structures with thermomechanical incompatibility of their components, these effects can contribute to their accelerated aging. At the same time, with the thermomechanical compatibility of materials, a more favorable distribution of internal stresses of thermal and mechanical origin is achieved, which excludes premature degradation of the strength of the contacting phases and the entire system as a whole. Using the methods of strengthof materials and the finite element method, it has been established that under the conditions of a change in the temperature of the system during its seasonal and daily fluctuations, shear stresses are subjected to the highest concentration. They are localized in the edge zone of the plane of contact between the layers and increase with an increase in the thickness and modulus of elasticity of the upper layer. These stresses are the main reason for the occurrence of plastic deformations in these zones and subsequent delamination of the structure in them. It is proposed to reduce the concentration and level of generated high-gradient shear stresses by reducing the thickness of the asphalt concrete layer in these areas.
Monitoring of the elements stability of building constructions by means of example of vertical elastic rod of high flexibility
Authors: Isaev Oleksandr , Annenkov Andrii , Demianenko Roman , Chulanov Petro
Published: February 2023

The article is related to the field of geodetic and engineering construction monitoring of building structures in the form of rod systems. It investigates the measurement accuracy of the compression deformation of the rod.  As an example, there is considered a vertical rectilinear rod of high flexibility, loaded with a longitudinal axial force. Experience demonstrates that the rod, under the influence of an axial compressive load not exceeding the permissible design values, retains its original form of equilibrium and stability. At the same time, it works in the field of elastic compression deformations. As the load increases to its critical values, there occurs a particular state of the element when the form of equilibrium becomes unstable, and at any moment, it can turn from a straight line into a curvilinear one with a slight external influence or as a result of position errors. This is accompanied by large displacements and permanent deformations. The importance of monitoring is noted when a building structure with similar constructions, for example, is situated in the area of development of negative natural and anthropogenic processes. As a result, the load on some elements may increase to critical values due to uneven horizontal and vertical displacement and inclination of the structure, including vibrations, etc. Attention is focused on the fact that the complex of engineering and technical measurements should show, with the necessary completeness, reliability and accuracy of the value, the nature and dynamics of changes in the external load on the elements of the building structure, changes in internal forces and stresses in them, the development of deformations (changes in the size and shape of equilibrium). There is explained the accuracy with which it is necessary to measure the displacement of the rod end during the deformation. There was derived the dependence with the help of which it is possible to see the root-mean-square error of the displacement measuring that depends on the choice of the maximum stress deviation in the sections of the rod made of a certain material.  There is laid out the calculation of the maximum stress deviation based on the stability and flexibility of the rod.

Published: February 2023

The impact of the elasticity of the polymer filler of a three-layer cylindrical structure of normal elliptical cross-section on its stress-strain state under internal impulse loading was studied. Determined values and distribution of normal deflections  and stresses  in sections S1 and S2. The finite-element method of calculating the stress-strain state (SSS) of such a structure by the software-calculation complex Fimap with NX Nastran was applied. Conclusions were made regarding the sufficient expediency of considering the elasticity of the filler when optimizing the design of such structures.

Increasing the elasticity of the polymer filler increases the strength and monolithicity of the layered structure. The use of this method ensures efficiency and is appropriate when the ratio of elasticity of the materials of the layers and filler is Е1.3 /Еt ≤50.
Searching for a compromise solution in cross-section size optimization problems of cold-formed steel structural members
Authors: Yurchenko Vitalina , Peleshko Ivan
Published: February 2023

A parametric optimization problem of cross-sectional sizes for cold-formed steel lipped channel structural members subjected to axial compression has been considered by the paper. An optimization problem is formulated as to define optimum cross-sectional sizes of cold-formed structural member taking into account post-buckling behavior (web and flange local and distortional buckling) of the member as well as structural requirements when the profile perimeter (strip width), profile thickness, design lengths of the structural member as well as material properties are constant and specified in advance. Maximization of the load-carrying capacity of the cold-formed structural member has been assumed as purpose function. The formulated parametric optimization problem has been solved by exhaustive search method using the software written in Python. As optimization results the cold-formed steel lipped channels with optimum cross-sectional dimensions have been obtained depending on the profile thickness and design lengths of the structural member. In order to obtain optimum solutions for cross-sectional dimensions of the CFS lipped channel structural members which are independent from the design flexural lengths and profile thickness, searching for a compromise solution has been performed by exhaustive search method. The obtained cold-formed steel lipped channel structural members with optimum cross-sectional sizes have higher design buckling resistance under the axial compression at the same material consumption (stripe width) comparing with the cold-formed steel lipped channels proposed by the manufacturer. Web local buckling phenomenon has been occurred in all obtained CFS lipped channel cross-sections with optimum sizes.

development projects of housing and communal services providers is carried out, the
limitations in which they function are given, the principle model of building the
organizational structure of the management of development projects is described, the
research methodology and architecture, a conceptual model of anti-risk management in the
development projects of housing and communal services providers is proposed for carrying
out further scientific research. An essential lever for increasing the effectiveness of
anti-risk management in the development projects of providers of housing and communal
services is the possibility of adjusting priorities regarding the implementation of
development projects in real time due to the introduction of management automation and
decision-making algorithmization, a process approach to risk management and management
decision-making, and a dynamic organizational structure of project management
development Automation of management and algorithmization of management decision-making
allows all participants of development projects to be in one information system: to
build a logical sequence of tasks, to determine the project path, to create an
uninterrupted material flow with the minimization of necessary stocks, to establish
transparency and control for stakeholders of development projects, etc. Algorithmization
of decision-making allows timely prevention of project volume growth, low productivity,
cost overruns, lack of time, resources, decision-making based on incomplete information,
incompetence of development project participants. The dynamic organizational structure
of management of development projects stimulates the coordination of actions and quick
resolution of issues, education of the personnel reserve, establishment of
communication, etc.
APPLICATION OF GIS TECHNOLOGIES FOR THE FORMATION OF THE GEOSPATIAL DATABASE OF
GASTRONOMY TOURISM OF UKRAINE

Gastronomic tourism as a rapidly developing type of tourism, and being a complex
system, requires quality management. The use of geoinformation systems and technologies
can contribute to the formation of management decisions regarding the effective
development of this type of tourism.

The article examines the essence of gastronomic tourism and the use of GIS technologies
to form a geospatial database. The cartographic method of researching the presented
phenomenon is applied and the possible cartometric operations in the work of the tourist
GIS of the gastronomic direction are described. In this study we have developed a
technological scheme for creating gastronomic tourism routes using GIS technologies. We
present the conceptual and structural-logical model of the geospatial database of
gastronomic tourism developed by us. A geospatial data base of gastronomic tourism for
Odesa region, which is distinguished by its gastronomic colour and is in great demand
among travelers, has been created and visualized. Local specialized objects of
gastronomic tourism of this region were found and the database tables were filled with
reliable attributive data. The locations of the concentration of gastronomic objects in
Odesa are visualized with the help of a heatmap, and typical requests of users regarding
the identification of objects of interest when designing gastronomic routes are given.
The city of Odessa was identified as the most attractive place for gastronomic tourism
in Odesa region, as it is the one around which the vast majority of various objects of
gastronomic tourism is concentrated. Various gastronomic routes through Odesa region and
Odesa with buffer zones along them have been designed, which can be of interest to both
tourists and tour operators when creating gastro tours. The proposed methodology can be
used for a similar analysis of other regions and, in our opinion, will contribute to
increasing the number of tourist trips to the region and the development of gastronomic
tourism in Ukraine as a whole.
MODERN INFORMATION TECHNOLOGIES FOR SIMULATION OF THE URBAN ENVIRONMENT AND
CREATION OF DIGITAL DUPLICATE OF CITY OBJECTS

Published: February 2023

The current stage of the development of the construction industry is its
digitalization, which requires the transformation of processes and models based on the
use of modern information technologies (IT) for the development of digital platforms and
duplicates. Urban planning is a complex process of controlled development of the city,
and the problem of digitalization of the city as a system as a whole has not lost its
relevance. The research examines the problem of selection, application and integration
of modern information technologies for modeling the urban environment and creating
digital duplicates of city objects as components of the Smart City system. An overview
of the main IT for the application of the methodological platform of information
modeling of cities (City Information Modeling) based on Building Information Modeling
(BIM), Geographic Information System (GIS) and Internet of Things (IoT) technologies,
which make it possible to combine city data of various spatial scales and time
dimensions. A conceptual IT scheme for urban space management is proposed based on the
integration of three components: the Artificial Intelligence system, Big Data
technology, and the CIM methodological platform. The requirements for the selection of
information technology for the creation of a digital double of an urban object were
studied, which made it possible to propose an integration scheme of IT modeling of the
urban environment and the creation of a digital double of the city. Such integration
will help to efficiently process large and complex data sets, use information about the
past and present to predict the future, implement digital reproduction of a physical
object and create a digital urban spatial object, namely a CIM object, which should
become a digital basis for intelligent planning, construction, management and operation
of a smart city.
