Abstract
The traditionally carried out evaluation of the technical state of monolithic reinforced concrete constructions can be qualitatively complemented by the use of the offered structural calculation approach. The essence of such approach is the analysis of damage which characterizes the active elements of a structure of the construction – technological cracks and internal surfaces of section, related to their internal and external safety. The objects of analysis are vertically formed elements of framed and monolithic (columns, diaphragms, elevator shafts) and monolithic (internal and external walls, partitions) residential buildings, according to the results of the research of which the active elements (TC, ISS) were fixed and damage coefficients within the fixed area on the levels of structural inhomogeneity «solution part - coarse aggregates» and «product» were calculated. In addition, in the course of work the actual problem of analysis of the influence of reinforcement on the formation of integral damage of the examined reinforced concrete constructions was solved. It is shown that tensile stresses from reinforcement, which modulus of elasticity is sequence higher than that of concrete impose on internal strain of the hardening concrete, acting both horizontally and vertically. The additional calculations of deformations, which are carried out on the basis of phenomenological approach, allow to quantitatively estimate possibility of appearance of «visible» cracks and the influence of reinforcement on forming a structure of the construction.
