Reducing the consumption of heat resources in construction and housing and communal services is one of the key tasks solved by design engineers. The increase in the thermal protection of buildings is determined by regulatory documents, but construction customers often require it to be strengthened without any feasibility study. The objective of the study is to develop a graphical-analytical model, the analysis of which allows you to choose the most optimal combination of heat resistances of the coating (walls) and translucent structures of a particular building object.

The problem of energy saving is one of the most pressing problems of our time. In the Russian Federation, especially in the northern part of the country, the task of energy saving is one of the first places. As you know, the main reason for the increased energy consumption for heating and ventilation of buildings is the low level of thermal insulation of the building envelope. The most vulnerable element for heat loss in buildings are translucent structures, through which more than half of the heat supplied to the building is lost. Thus, to solve this problem, it is necessary to look for ways to increase the resistance to heat transfer of window structures and increase their thermal characteristics. One of the solutions for improving the thermal characteristics of translucent structures is the use of protective and heating films. In this work, we carried out experimental studies of the effect of the heating element on the thermal characteristics of window constructions compared to a window without a heating element.

The question of the spatial and temporal forms of the architectural composition of urban development is considered. The philosophical and technical problems of using architectural forms and styles are solved. Revealed current opportunities for improving modern architectural composition. The concept of “time” in architecture is also used in various semantic evaluations. This meaning is often determined by the length of time, by which we denote large historical rhythms determined by social processes (alternation of social formations, change of styles in art); seasonal and daily rhythms determined by natural cycles that are the basis of all time measurements; periods of internal changes in the architectural form and, finally, smaller divisions - rhythms in the activities and perceptions of people). Within each time interval, in turn, certain changes are highlighted - the initial, the climax and the completion. Discrepancies between different time cycles at the same and in those spatial boundaries lead to different contradictions: between the periods of moral and physical aging of the building, between the time flexible function and the rigid spatial structure, between changes in natural climatic conditions and stability of the building envelope. The desire of architects to solve contradictions, to provide the most flexible flexibility in the function, to extend the moral life of the object - reflect the various theories of mobile architecture. Such developments emphasize the need for project-based time factor or “time design”. This article is useful to future architects for the formation of modern thinking about architecture, and architects with work experience who need to improve themselves as specialists.

The article proposes some innovative technical solutions to build a multistory substructure for residential and public buildings. To erect a building, it is proposed to construct a system of interconnected rail runways at a first storey level along which travelling gantry cranes and special platforms will move. To descend the machines, building materials, instruments to the design level, during the underground space development, it is proposed to employ travelling gantry cranes. In order to quickly relocate loads and machines from one work zone to another, an additional system of rails is mounted along which special platforms are moving. The management of the gantry cranes and special platforms movement is done by the remote operating panels. The superstructure is built in the traditional way using a tower crane, track mounted, for example. The application of the proposed designs when building multistory substructures will enable to improve the technological processes of building the substructures. The proposed technology will help to use it in all the climatic areas of our country.

The paper underlines the need for use of composite and nano-materials in place of natural materials, which is explained by depletion of global resources and increasing environmental pollution. This is why the focus is currently shifting toward the use of a composite material – porous artificial wood (PID-IV) – developed by the Irkutsk State University for making framework systems required to strengthen rectangular structural elements of buildings and structures. The framework system in question has a deck made of PID-IV. Further, the structural test was carried out in line with the effective regulatory documents, and the use of the suggested framework system was substantiated.

In the article numerical simulation of the interface zone of a tunnel with a vertical barrel by the finite element method is considered. The numerical spatial model is a fragment of a rock mass with a size of 80 to 90 meters, in which the tunnel is connected by a span of 6.0 m, adjacent to the vertical trunk. The mating and trunk in the area under consideration are fixed with reinforced concrete lining 500 mm thick. A universal spatial isoparametric eight-node finite element is used to break up the model. The dimensions of the finite elements on the outer regions of the model were 2.5 - 5.0 m, on the inner - 0.25 - 0.5 m. Thus, the principle of combining dense and rarefied grids was used to reduce the amount of information describing the numerical model. The problem was solved in an elastoplastic formulation by a stepwise iteration method. As a result of calculations, all the components of the volumetric stress tensor in the finite elements of the lining and the rock mass, movement and deformation in the nodes of the finite elements were determined. With the help of the developed numerical models, a series of calculations was performed, an array of data was obtained on the stress-strain state of the lining in the zone of coupling effect, quantitative and qualitative analysis was performed. It is established that in characteristic zones of the influence of conjugations, a significant increase in the intensity of equivalent stresses is observed, which leads to a reduction in the load-bearing capacity of the lining by 2 times or more in comparison with extended sections of underground structures. To increase the efficiency of maintaining interfaces during tunnel operation, it is necessary to justify the control actions taking into account the dynamics of changes in the stress-strain state of the lining in space and time.
