The article deals with the stages, causes of origin and actual problems of high-rise construction in Rostov-on-Don. Examples of successful development of high-rise buildings in Russia and abroad are given. The problematic aspects are analyzed, possible ways of solving on the basis of the experience of other cities in the construction of unique buildings are shown.

We consider eccentrically compressed rod elements of reinforced concrete structures. Problems are solved for the development of methods for calculating the strength of normal sections in the case of eccentric compression of reinforced concrete elements; calculation of the load-carrying capacity of reinforced concrete structures by the example of columns of varying flexibility for ultimate effort. Analytically, a calculation is made, which makes it possible to determine the strength of reinforced concrete structures.

Discusses the construction of the supporting ring beams steel bins on separate supports. The problem for the development of algorithm and program of calculation of the reference ring beams, steel silos, the combined effect of bending and torsion. Analytically developed a calculation program that allows for the analysis work on the combined effect of bending and torsion when the geometric parameters of the cross section.

Keywords: basic ring beam for steel silos at certain poles, steel silos, bending, torsion, geometric parameters of the cross section, normal tension, torsion torque, bimoment

Air environment workspaces enterprises building industry characterized by complex migration cycles of matter and energy. The priority is to identify the isselodovany vzaimo¬deystvuyuschih in this process objects as dynamically developing systems. The implementation of any production and technological process is accompanied by the mandatory application of a set of measures to ensure the specified level of MPC in the air.
