Title of the articleMethod of calculation of reinforced concrete bendable elements for endurance by limiting forces
Abstract.Problem statement. In reinforced concrete bendable structures, under cyclic loads in the compressed zone of concrete, inelastic deformations of vibration creep are manifested and develop under connected conditions. This leads to non-stationary modes of deformation of concrete and reinforcement. Endurance calculation is a complex and difficult process. Therefore, it is necessary to develop a simplified methodology based on the well-known limit state method. Results. Experimental and theoretical studies of the endurance of reinforced concrete structures, under stationary and non-stationary modes of repeatedly repeated cyclic loading, have been carried out and a simplified method for calculating endurance by limiting forces has been developed. Conclusions. A new method has been developed for calculating the endurance of reinforced concrete structures by limiting forces under cyclic loads regime. In this simplified substitution, the change in the stress-strain state of the concrete of the compressed zone and the longitudinal stretched reinforcement is considered, taking into account the redistribution of forces between them in the process of cyclic loading.
