Analysis for Collapse Process of Multi-Layer RC Frame Structures under Earthquakes

Abstract:

Multi-storey RC-frame structure occupies a large proportion of the building structure in our country, the collapse of multi-storey frame structure in great earthquake is very serious, and it has become a major threat to people's life and property security, so research of the rule about structural collapse and define the critical state of structural collapse accurately is necessary. This paper focuses on the rule of structural collapse, takes constant stiffness multi-layer RC-frame structure as the object of study, with height, span and number of floors as the variables, uses nonlinear finite element software ANSYS/LS-DYNA, bases on elastic-plastic time history analysis, studies the rule of plastic deformation’s development of constant stiffness multi-layer RC-frame structure, and the relationship between story-drift and structural collapse.
