Evaluation of seismic analysis in diverse effect position of shear wall for reinforced concrete frame building
Shear wall is important and suitable part in high-rise building to carry (support) dead loads and resist lateral loads (wind and seismic), shear wall's position in the building influences on the all analysis and design's behavior of the building. This paper presents the different positions of shear walls in the building as well as effects of different position of shear wall on the building's behavior of analysis including; displacement, shear force and bending moment. Considering this case the results in different effect positions of shear wall for a building which represent G+17 storey separated into four different models. The analysis of different position of shear wall, which is using equivalent lateral load method in the building, have been performed by using ETABS 2016 Structural analysis software.

Thermophysical models of pavement research and control
This article deals with a thermophysical method for studying and monitoring the condition of pavements, as well as ways to improve the energy efficiency of the road network. The following directions were considered: the apparatus of thermodynamic functions, developed in the works of Goryachev M.G.; And Zavyalov M.A. (with colleagues); the thermofluuation model proposed by Kiryukhin G.N.; "urban heat island effect" and methods of creating "cool" asphalt; the process of "escorting" the bowls of the bending motion of a moving vehicle; the question of the rational number of passage by the roller on the surface to be repaired during its compaction; ways of accumulation and use of energy circulating near the road (solar, wind, kinetic and thermal energy of transport, etc.).

Monitoring and quality assessment of urban development areas based on neural network modeling and GIS
In this article the authors carry out the research of the urban development areas structure and propose the system of its characteristics on the basis of sector affiliation of the municipal economy. The authors have developed an algorithm for quality assessment of urban development areas. The results of the research are presented on the example of several central city quarters of Arkhangelsk. Structural SOM-analysis compiled separate quarters of Arkhangelsk into 5 groups with a high level of characteristic similarity: "Commercial", "Prospective complex development", "Sustainable development", "Perspective renovation of residential development", "Investment-unattractive". Typical development strategies for each group of quarters are determined. Using GIS allows to visually reflect the state and assess the quality of the urban development area by the aggregate of all parameters, and also to assess the quality of the quarters for each sector. The proposed method is universal. It makes it possible to vary the list and the set of characteristics; to apply the method for monitoring and assessment of different areas, regardless of their geolocation and scale; to adapt the methodology for monitoring other processes occurring in urban areas. "Fast" algorithm processing allows one to accelerate the planning and adjust the programs of urban areas reproduction in real time, reduce the expenses of time and resources on monitoring and analyzing data. The proposed methodology can be used as a mechanism for the formation of a long-term town-planning strategy for the urban development area along with the planning of reproductive activities taking into account their investment and social efficiency.

The pressure loss and the filtration coefficients in pipelines with grids
A variety of grids and lattices that occur in different spheres of practical activity requires detailed study. The presence of these devices leads to additional resistance and energy losses during their flow. The paper discusses a flat plastic perforated mesh with different degree of permeability at the outlet of the pipeline. The coefficients of grid resistance were determined experimentally. The effect of grids on the total head loss were established through the presence of resistance coefficients volume method at fixed pressure: we determined the flow at the exit of the horizontal pipe of constant cross section, the end of which was mounted the investigated grid. To precise definition, the obtained values along with the experiments on the measurement of costs used a method of determination using piezometers: according to the length of the flow part were installed piezometers and the values of the coefficients of resistance were established on the basis of differential pressure. The identity of the two methods of determining the resistance coefficients is shown, in terms of flow rate and pressure drop on the grids. The effect of grids on the capacity of the pressure pipeline has been established: the replacement of the flow part does not affect to the numerical values of resistance coefficients of the grids. The dependence of the relative flow rate in the pipe on the surface porosity of the grids is obtained; this dependence gives a qualitative estimate of the reduction in the capacity of the pipe in the installation of meshes. The experimental data for constructing this dependence agree with the calculations for the approximating dependence established earlier. The transition from resistance coefficients to filtration coefficients and permeability of the pipeline with grids is suggested, because it is more convenient in practical calculations by characteristics. Graphs of the permeability coefficients dependence, related to the pipe cross-section area, and the filtration coefficients on the surface porosity of the grids are given. The proposed dependencies are linear functions of the surface porosity.

Predicted temperature dependence of the road surface on the air temperature in a variety of road-climatic zones of the Russian
The paper studies the temperature dependence of the surface of the asphalt concrete on the temperature of the environment of different Russian cities road-climatic zones with a view to determining the most effective method of calculating the temperature of the coating of the road. There are the materials of research, which shows that the fluctuation range of the surface temperature of asphalt pavement is roughly proportional to the range of air temperatures. Especially dangerous is winter and spring period, when the change in temperature occurs unevenly, as a result of which there is a decrease in strength and deterioration of transport performance indicators. Seasonal and diurnal variations of the temperature of pavement can be levelled by applying a special composition, which allows to maintain approximately the same temperature of the coating during the entire period of exploitation.

Efficiency of applying sustainable technology of bubbledeck technology in concrete in Russia
The idea of optimization concrete use, reducing its amount and applying new technologies, is not novel one. During the last three decades there were several studies and projects, in which concepts of slab with voids were used. Bubbledeck technology consists of hollow slabs and plastic balls in it, which serves for reducing of concrete volume. In this article Bubbledeck is estimated for Russian construction market. Possibility and efficiency of appliance this technology is assessed. Construction methods, sustainability and properties are considered. Inputs of bubble’s construction, concrete and technology are compared with the costs of using conventional concrete. Basing on these data suggestions for effective technology implementation and appliance are given.

Building energy model detail level
Three energy models of the apartment building with different level of detail were studied. The study was carried out to assess the possibility of simplifying the model of the late design stage or using the model of the early design stage to perform energy calculations. The maximum divergence of the calculation results of the simplified and detailed models did not exceed 10%. On average, the divergence of the results was equal to 8% in the case of the calculations of the concept and detailed models, and the divergence of the results was equal to 5% in the case of the calculations of the moderately simplified and detailed models respectively. In the case of energy calculations at the early design stage it can be considered a rather small value. The use of the simplified building model for energy calculations can be recommended. The use of the detailed model was considered to be irrational and can be recommended only in the case of the existence of compelling reasons.
