Analysis of Storey Damage Effect Factors of SRC frame-RC Core Tube Hybrid Structure under Cyclic Loading

摘要

Based on the general finite-element software ABAQUS, the FE model of 30-story SRC frame-RC core tube hybrid structure is built up. The maximum story drift angle of the structure under cyclic loading can effectively characterize the changes in storey damage. With the new achievements on damage effect factors, the relation between storey damage and component damage of various types and influence of the main design parameters on the storey damage law are analyzed. It is found that storey damage degree is more serious with the increase of stiffness character value and shear wall depth-thickness ratio, but the effects of both of them are gradually weakened and the change range of it is really small. Research will provide theoretical support on the building of hybrid structure damage model under earthquake excitation.
