Sažetak
During the research, the main causes and consequences of damage to reinforced concrete eccentrically compressed structures of the H- shaped cross-section were established Three main factors that affect the value of the residual bearing capacity of the elements are identified. A three-level three-factor Boks-Benkin plan has been created, which will give statistically substantiated results (within the variation of variable factors) in the research of only 15 experimental columns. Samples of compressed elements were made and tested (according to the experimental plan). As a result of the experiments, data were obtained that allowed us to describe the stress-strain state of the damaged H- shaped reinforced concrete columns. The dependences of stresses in reinforcement and relative deformations in concrete on the parameters of damage and load level are obtained. Based on the analysis of scientific proposals and the stress-strain state obtained experimentally, the basic preconditions for calculating the residual bearing capacity of elements damaged during the operation of structures are adopted. A system of equations is developed, as a result of the solution of which the value of the residual capacity of the damaged columns is obtained. A system of equations is created and the ways of its solution are planned. Proposals for determining the residual bearing capacity of damaged reinforced concrete compressed columns are based on the main provisions of current regulations and extend their effect to damaged structures of the most common cross-section – H- shaped.
