Modern economic conditions require construction companies to promptly prevent, identify and manage risks in various areas of their construction activities. As this research shows, many of the best practices of corporate risk management are adopted and applied in large Russian construction companies and in various industries. At the same time, the results of the research demonstrate the possibilities for further development. Key areas of development include: the process of integrating risk management into the development strategy of a construction company, the collection and accumulation of statistical data, interaction between units, the participation and active participation of key stakeholders, and the quality of information on key risks. Risk management is one of the most important functional areas in the methodology of project management in the construction sector. In practice, as a rule, in addition to quantitative risk assessment, qualitative risk assessments in construction is also always utilized. However, the theory of risk management based on qualitative assessments is virtually absent in the Russian practice. This article provides a definition of qualitative risk assessments and complex risks in the construction field. We desceibe the tasks involved in risk management in construction and propose algorithms for solving corresponding problems in the construction field.

Abstract. An approach to the assessment of long-term strength and durability of concrete in multi-layer section of enclosing structures by numerical integration of the equations of physics that for practical calculations provides more accurate evaluation of the actual stress-strain state of a bended three-layer element, taking into account the characteristics of deformation layers.

Abstract.The basic assumptions and hypotheses construction of the computational model studies, taking into account the peculiarities of the work force imperfections of materials under dynamic loading, based on the phenomenological laws of nonlinear rheology and deformable elasticcreeping body. The values for the coefficient vibrocreep computational model under triaxial stress-strain state on the basis of the hypothesis of central symmetry of the hysteresis loop. The basic phenomenological equations allow the calculation of concrete elements in the conditions of triaxial stress-strain state under dynamic impacts and taking into account the non-linearity of the rheology of deformation.
