Features of Elastic-plastic Deformation of Reinforced Concrete Shear-wall Structures under Earthquake Excitations

Abstract

The article provides the results of studies the process of formation and development of plastic deformations in reinforced concrete structures with shear-wall under earthquake excitations. The studies are carried out by numerical methods using nonlinear dynamic analysis. The results of the research shown: that in the shear-wall elements of reinforced concrete structures the level of plastic deformations should be significantly reduced in relation to the normative level of plastics in other structural elements of the carrier system. The completed studies substantiated the introduction of differentiated values seismic-force-reduction factor for different types of structural elements on shear-walls reinforced concrete structures of earthquake-resistant buildings.
