Analysis on the Ductility Performance of Reinforced Concrete Coupling Beams in Shear Wall Structure

摘要

Coupling beam, the first line resisting earthquake, is directly related to the overall performance of the shear wall structure. Using the large general finite element analysis software ANSYS, the coupling beam span-depth ratio is 2 ～3 different reinforcement scheme in finite element analysis. Analysis on the ductility performance of reinforced concrete coupling beams in shear wall structure in three fields: the concrete strength grade, the longitudinal reinforcement ratio and the stirrup ratio, provides a basis for the design of the structure and to provide a reference for similar studies.
