Authors: Matveeva M V , Filatov E A 
Published: May 2021

Abstract
In the context of the COVID-19 pandemic and other crisis phenomena, we can conclude that the construction industry in the Russian Federation is characterized by pessimistic sentiments regarding financial indicators for 2020. Under these conditions, the self-survival of the Russian construction industry is largely determined by the ability of specific construction companies to adapt to the changed economic environment, fully realize their internal reserves, and diversify production in search of new markets. This increases the role of analysis in assessing the production and commercial activities of the construction industry of the Russian Federation and, above all, in the availability, placement and use of their capital and income. The results of this analysis are necessary, first of all, for the owners (founders) of the construction company, its creditors and investors. The article analyzes the model of financial dependence. The object of research of the article is the construction industry of the Russian Federation in the context of three main types of construction: construction of buildings; construction of engineering structures; specialized construction works. The article describes one of the author’s methods of integral factor analysis, which allows you to assess the degree of influence of factors on changes in the resultant indicator in an accessible and relatively simple way.

Abstract
The article is devoted to the analysis of the problem of balanced development of the housing sector in the regions of the Russian Federation. The relevance of the research is determined by heterogeneity of the socio-economic filed of the Russian Federation and necessity to ensure a balanced development of the housing sector in the country’s regions as the most essential condition for leveling-off the living standard of the population. The article studies the current condition and development of the housing sector in the Russian regions through a system of indicators that characterize dynamics of the housing investment market and the population’s housing conditions. The authors of the article propose an approach to assessment of territorial differentiation of regions’ housing development levels based on the use of statistical analysis methods. The developed approach involves determining the integral index of the current condition and development of the housing sector in regions by aggregating the values of individual indicators that characterize dynamics of the regional housing investment market and housing conditions of the region’s population. The approach proposed by the authors allows us to analyze the housing sector as a complex system, characterize dynamics of its development and expose its results. The article tested the developed approach: it assessed the current condition and level of development of the housing sector in 80 regions of the Russian Federation and analyzed the balance of its development.

Published: May 2021

Abstract
Bridges are an important part of traffic engineering. They play an irreplaceable role in developing national economy, promoting cultural exchanges and consolidating national defense. The structural safety of bridges is the primary prerequisite for their role. However, due to the influence of many factors such as material aging, external environmental corrosion, longterm load action and accidental impact, the bridge structure will be damaged to different degrees, and the bridge will be destroyed when the damage accumulates to a certain degree. Once the bridge is damaged, it will have a great negative impact on human life safety, property safety, and social stability. Therefore, studying the method of rapid and accurate identification of bridge structure damage has great theoretical significance and engineering value. Based on the current status and existing problems of existing bridge structure damage identification, this paper proposes a continuous beam bridge structure damage identification technology based on deflection influence lines. Firstly, using graph multiplication and other theories, the expression of influence line function on the deflection of multi-span continuous beam bridge is derived. The influence line function of continuous beam bridge without structural damage is derived from the theoretical level, and the graph is drawn. Through the formula of the deflection influence line of healthy structure, it can be confirmed that the deflection influence line obtained quickly under the visual tracking technology can identify the damage of the structure. We use software modeling to find the best identification parameters. Using MIDAS/Civil software can establish the model and simulate the deflection influence lines of different measuring points of continuous beam bridge structures with different positions and different degrees of damage under the action of moving loads. Taking the continuous beam bridge deflection influence line, the difference between the deflection influence line of the first derivative and the second derivative, the first derivative and the second derivative and other parameters as the research objects, we explore how to use the deflection influence line to identify damage. Finally, after the comparison of multiple working conditions and multiple measuring points, it is found that the damage identification effect of the first derivative of the deflection influence line difference is the best.

Published: May 2021

Abstract
The gradation and fineness modulus of machine-made sand are important factors affecting the performance of mortar. By studying the influence of different machine-made sand gradation and fineness modulus on the workability and rheological properties of mortar, the gradation and fineness of machine-made sand are explored. The relationship between modulus and mortar fluidity, yield stress and plastic viscosity. Research shows that with the increase of the cumulative screening rate and fineness modulus of machine-made sand with different gradations, the fluidity of the mortar increases and the workability of the mortar increases. The cumulative screening rate and fineness modulus of machine-made sand are negatively correlated with the yield stress and plastic viscosity of the mortar. The cumulative screening rate and fineness modulus of machine-made sand have a good correlation with the yield stress of the mortar, and the mechanism is 1.18-0.6mm Sand gradation is significantly negatively correlated with the yield stress of mortar, and the cumulative sieving rate and fineness modulus of machine-made sand have poor correlation with the plastic viscosity of mortar.

Published: May 2021

Abstract
Due to the limitation of engineering conditions and meteorological conditions, the on-site measured data inside the cooling tower is relatively lacking. Field test data for ribbed cooling towers is even less. In order to provide a scientific wind load basis for engineering design, we choose a bibbed cooling tower for field measurement in Toksun County, Xinjiang, which is windy all the year round, so as to understand the inner wind load characteristics of the cooling tower under the prevailing wind direction and the maximum wind speed direction. It is found that the average wind pressure coefficient measured in the field is not completely consistent with the wind pressure coefficient in the Code.
