Authors: Konstantinov A , Verkhovsky A 
Published: March 2020

Abstract
The PVC windows application experience in various climatic conditions shows that at their operation the windows profile deformations can be observed. One of the reasons for these deformations is the climatic loads influence on the windows – wind pressure, solar radiation, negative outside temperatures. The profile elements deformations affect the window tightness and the normal window hardware operation. The calculated loads combinations on windows in winter and summer were analyzed. For window as external element of building is more critical winter loads combination – the combined effect of wind pressure and negative temperature. The work was done the analysis of the effect of negative temperatures and wind pressure on the PVC window deformation. The studies were performed in laboratory conditions on the basis of two testing centers. Three PVC Windows with different profile thickness were tested. The temperature deformation of the casements and mullions profiles of this windows were analyzed. These deformations have to take into account in the static calculations. But the engineering methods creation for calculating windows for the wind and temperature loads effect requires additional research. They are associated with the study of the joint work of the windows constituent elements (profiles, insulating glass units, hardware).

Published: March 2020

Abstract
The use of recycled materials as a product of household waste recycling to reduce environmental pollution, as well as to obtain cheap aggregate for the manufacture of concrete is considered. During the laboratory tests, the strength of concrete was found by a non-destructive method of controlling the strength of materials - by the method of a shock pulse using an electronic strength meter IPS-MG4.01. The uniformity and class of concrete are determined on the basis of measuring the time and speed of propagation of ultrasound in them. Compression tests were carried out on parallelepiped samples of 390×190×188 mm in size, consisting of Portland cement, sand and household garbage. Significant differences were found from the indicators of the considered analogues, such as relatively low values of strength and frost resistance of the samples; but at the same time, the low cost of finished products due to the actually free aggregate, as well as the relatively low weight of the samples. Recommendations are given on the selection of the ratio of aggregate components to improve the properties of concrete as a whole. Areas of application for concrete blocks from household waste are offered.

Authors: Tolstoy A D , Fomina E V , Milkina A S 
Published: March 2020

Abstract
The use of fine-grained high-strength concrete of man-made materials as components entails the risk of corrosion processes in concrete. A peculiarity of possible corrosion processes is iron-containing sulfosilicating compounds in rubble, which greatly complicates the prediction of structure durability made of such concrete. High-strength construction composites, which differ from ordinary concrete with a higher content of cement stone, fine particles of binder and fillers, as well as a multi-component composition, necessitate the development and modification of ways to increase and predict structure durability made of such materials. The paper deals with design and technology of product manufacturing from fine-grained high-strength concrete of increased durability in close connection with the assessment of their reliability and durability.

Authors: Bulushev S V , Dudareva M S 
Published: March 2020

Abstract
The problem of modeling reinforced concrete structures with bar finite elements using a nonlinear material that allows to consider the direct reinforcement is studied. An approach to the creation of a computational model of a reinforced concrete column is proposed, the peculiarity of which is to specify reinforcing bars at the appropriate integration points of the cross-section. As a material of reinforced concrete bar elements, a nonlinear material based on Eurocode-2 is used, which can model the nonlinear behavior of both concrete and reinforcement for different integration points. Numerical experiments were carried out using the LS-DYNA software package. The results of the calculation of the bar reinforced concrete column are compared with the data for the column modeled using solid finite elements with direct reinforcement. In addition, a comparative analysis of the studied column with the results of full-scale tests is performed. Studies have shown good convergence of stresses, strains, and displacements, as well as the coincidence of the value of the ultimate breaking load and the similar nature of the destruction of the reinforced concrete column.

Authors: Lukonina T A , Aksenova I V 
Published: March 2020

Abstract
The article is focused on the problem of preserving the ownerless historic manor complexes (HMC) and their restoration on the basis of commercial use in conditions of public-private partnership. Basing on the theoretical R & D done in the recent years and on their study of the experience gained in the best practices of capitalizing the architectural heritage, the authors identified possible options for the use of estate complexes and formalized a minimum list of the key HMC indicators affecting the further choices. Proceeding from the prescriptive literature, they determined the values and the importance degree of key indicators for each use option. Further on, using the method of multivariate analysis of variance, the authors adjusted the process to juxtapose the values of the key indicators of the estates with the specified conditions for each option and automated that process by means of software support. The result of the work appears in form of the analysis matrix, which automatically performs the multifactor analysis of the estate complex and helps to select the most rational use of the given HMC. The proposed method of express analysis makes it possible to determine the most effective options for the modern use of each particular estate, depending on its indices. This will reduce the risks of potential investors, attract the inflow of investments into the restoration and thus contribute to the revitalization of the estates by integrating them into the Key words: manor, historic manor complex, architectural monument, restoration, commercial use, use cases, express analysis.
Influence of Fluid in Dynamic Calculation of Thin-Walled Cylindrical Tanks by Means of Calculating Added Masses of Fluid
Authors: Leonenko Yu S , Chemodurov V T 
Published: March 2020

Abstract
This paper presents the exact solution for the problem of the added masses of fluid, oscillating inside a cylindrical tank. A thin smooth cylindrical shell of finite length, filled with the ideal incompressible fluid that is subjected to transient dynamic load (it may be an earthquake, air explosion impact, etc.), is taken as a design model. In this case, the shell of a tank becomes a part of the oscillating process along with the fluid stored inside. The shell bending equation (stipulated by the membrane theory of shells) is taken as a design model for this case. In this equation, the shell deflection is expanded into Fourier series by oscillation modes, and the velocity potential takes the form of the Laplace’s equation. Fluid’s inertial reaction to the shell motion is covered by the shallow water theory, which is specified by the boundary free surface conditions and the influence of the tank hard bottom. These mathematical expressions of the shell response to the external transient impact are solved by the Bubnov–Galerkin method with the transformation of the initial relations into a system of ordinary differential equations, which include expressions for determining added masses of fluid by oscillation modes of the elastic shell.

Authors: Korol O A , Butaev R Sh 
Published: March 2020

Abstract
The main types of energy consumers on the construction site are: construction machines, processes and infrastructure of the construction site. According to research and practical experience, more than 50 varieties of construction machines and mechanisms are used at various stages of construction of the property. Construction machines and mechanisms are integral elements of construction production. For each of them use different types of fuels: liquid fuel, gas, electricity, etc. Also various types of energy processes and maintenance of the construction site. The integral estimation and correct comparison of all energy consumption allows to carry out only their representation in the form of conditional indicators to which all others are given. In comparison with the point construction, the construction of a complex of buildings is characterized by a high integral level of energy consumption. The choice of the method of work production is decisive. This method determines the simultaneous operation of a large number of construction equipment, which leads to a significant increase in energy costs. Analysis of the parameters of organizational and technological models and their corresponding schedules of energy consumption allows you to choose rational organizational and technological solutions for the construction of complex buildings that reduce energy consumption during the construction of buildings.

Authors: Polikutin A E , Pinaev S A , Zyabukhin P A , Oforkaja T O 
Published: March 2020

Abstract
This article presents the results of testing the strength of samples of rubcon and fiber rubcon beams of a T-section, with a different percentage of longitudinal reinforcement. Rubber concrete (or abbreviated as rubcon) is a highly effective composite polymer concrete based on liquid rubber, which has favorable physical and mechanical characteristics, as well as almost universal chemical resistance to corrosive media. Bars of class A500C were used as longitudinal reinforcement; as transverse-Bp500, with a diameter of 5 mm and a step of 50 mm. Fiber reinforcement is represented by steel fibers with a diameter of 0.3 mm and a length of 30 mm (that is, a ratio of diameter to fiber length of 1/100) arranged randomly throughout the entire volume of the experimental beams. The section of the beams is assigned with the requirements of CR 63.13330.2012 “Concrete and reinforced concrete structures”: length - 1400 mm; web height - 95 mm; web width - 60 mm; flange height - 25 mm; flange width - 240 mm; the number and diameter of the longitudinal rebars - 0; 1Ø8; 1Ø10; 2Ø10; 2 Ø12 mm; which corresponds to the percentage of longitudinal reinforcement - 0; 0.80; 1.25;2.50; 3.60%.
The technique of experimental studies of bending elements of mixed reinforcement is described.
The results of testing beams for pure bending are presented. It is established that with an increase in the percentage of longitudinal reinforcement, the value of the destructive bending moment increases in a linear relationship. When adding fiber reinforcement, an increase in the values of the destructive bending moment is observed up to 10%.

Published: March 2020

Abstract
With an increase in the density of urbanized areas in order to create a comfortable living environment, organizational and technological solutions for exploited roofing with landscaping systems have found application in construction practice. Traditional rooftop technology is not always suitable for roofing with greening systems. The use of green space on the coatings of buildings and structures changes the specifics of the production of roofing work in the construction process, taking into account the adopted structural and technological solutions. These decisions in most cases have characteristic features that must be considered in the process of formation of the composition and sequence of technological processes and operations, as well as the choice of rational organizational and technological procuring of roofing devices with greening systems.
Principles of Urban Planning Development of Suburban Belt of Samara-Togliatti Agglomeration
Authors: Gud’ I D , Akhmedova E A 
Published: March 2020

Abstract
The article deals with the solution of such issues that are associated with the development of the suburban belt of Samara-Togliatti agglomeration-conurbation (STA) and problems that are connected with infrastructural changes in the region. The article shows the results of theoretical researches in the sphere of territory and settlement spatial development. There is considered historical development of the settlement structure of the Samara guberniya. The infrastructural support of the forming the Greater Samara megapolis is considered in the dialectical contradiction of internal and external factors in cooperation with the global transport map. There are made practical proposals of a territorial settlement system formation of the Samara guberniya based on the development of related towns in the structure of the STA suburban belt with peripheral local rural settlement systems. There is considered the potential development of the STA subcenters (Samara-Arena, aerotropolis Kurumoch, Krasny Yar, Kinel, Dubovy Umeet, Chapaevsk, Bezenchuk) and potential contact points of the STA suburban belt with local settlement systems (Dimitrovgrad, Otradniy, Pestravka, Novospasskoye, etc). The authors of this article were tasked to explain the principles of phased development for the near, medium and long-term perspective of the STA transport and communication framework. Currently, there are strong centripetal trends of movement from rural settlement systems to subcentres of STA. To create the opposite centrifugal movement, it is proposed to develop capital residential and industrial construction in potential contact points of the STA suburban belt with rural peripheral resettlement systems, creating employment for high-qualified labour. On the 2nd phase, these traffic flows should be strengthened by high-speed railway transport. The authors propose variants of the placement of multimodal transport and logistics hubs (Multihub) in promising “growth poles”, which are planned to be at the contact points of the peripheral suburban belt STA with local rural settlement systems. In the long term it is suggested to identify areas of town-planning reserves for the formation of Multi-hubs in order to include the Samara guberniya in the structure of the currently planned international transport corridors Europe - America and the Arctic – Southwestern Asia. There is emphasized the development of the south and the south- east direction, the perspective development of the transit railways network.

Abstract
In the framework of the preservation of historical and cultural heritage, it is important to provide for the possibility of preserving and recreating a virtual historical model of the city, first of all - architectural structures. To obtain reliable spatial data about the location and configuration of the building, tacheometric survey, laser scanning and photogrammetric methods are usually used. In this paper, an experiment was conducted to obtain a three-dimensional model of the building using all the above methods. As a result, the following conclusions were made: all technologies allow us to obtain a 3D model of the property; in time field and office work, the advantages are laser scanning technology and photogrammetric methods with UAVS; in terms of efficiency, it is possible to distinguish aerial photography from UAVS, since it is relatively inexpensive compared to laser systems; in accuracy, tacheometric survey will have an advantage, since measurements are made at a specific point, and its coordinates are calculated, but this advantage can only be for buildings that are simple in geometry, for complex architectural forms and complex technical structures, the use of an electronic tachymeter is impractical

Abstract
City courtyards built during the Soviet period do not meet modern requirements. There is a need to develop new approaches to the organization of the urban courtyard environment. The organization of the courtyard space should reflect today’s trends in architectural creativity, as well as changes in the lifestyle of a modern person. The task of the designer is to create a comfortable, harmonious spatial environment of urban courtyards, including the architecture of buildings, landscape, color and lighting solution that takes into account the culture, ecology, natural components, climate, functional and aesthetic requirements, safety, barrier-free environment. The environment of the city courtyards must comply with the modern level of technologies and include high-tech materials. When organizing city courtyards, it is necessary to design an environment that takes into account new requirements, to organize a flexible, changeable environment. Innovative technologies and modern techniques of design and construction give the designer more opportunities to create a highly artistic image of the courtyard space. Designers have the task to create conceptual, bright solutions for courtyard projects. The article discusses the modern requirements for city yards, affecting the quality of life of citizens, which have an emotional impact on a person.
Low-Rise Monolithic Steel-Reinforced Concrete Houses on the Basis of the “Load-Bearing Floor” Constructive System
Authors: Nazarenko A S , Zakharov A V 
Published: March 2020

Abstract
The load-bearing floor is a box-shaped structure consisting of monolithic floor slabs cohesive with all walls and partitions located between them [1]. The load of the bearing floor is transmitted only to the exterior walls. Thereby, the spaces within the outer walls located under the bearing floor and above it don’t require any intermediate support. The effectiveness of the load-bearing floor construction implementation is the ability to obtain freedom while making planning decisions, re-planning in the process of the operation and reducing the consumption of structural materials for creation of the building carcass compared to the existing traditional structures [2]. In [3] authors describe the technology of construction of the bearing floor and present the results of computational studies of the stress state of its elements in their different design. In this article we discuss the planning and design features of the load-bearing floor in steel-reinforced concrete structures of low-rise buildings.
