过渡层形式对SRC-RC混合框架结构抗震性能影响
Influence of transition layer form on seismic performance of SRC-RC vertical hybrid frame structure
摘要
Abstract
Because of the change of bearing capacity and stiffness,the transition layer of SRC-RC vertical hybrid frame structure is easy to form a weak layer,which will affect the seismic performance of the structure.In order to solve the problem,13 structural models are established and the seismic performance of SRC-RC vertical hybrid frame structure which the number of floors of transfer column is not in the same floor is studied through static nonlinear analysis by using the large finite element software SAP2000 inthis paper.This paper studies the Influence of transition layer form on seismic performance from 4 aspects which include horizontal bearing capacity、deformation ability、structure displacement base shear-vertex displacement relation 、plastic hinge distribution.The results show:the transition layer structure on both sides of the column when the highest floor,the central column of the transition layer,the structure of the horizontal bearing capacity is the highest,increased by 398kN compared with RC frame structure;when the transition layer column of SRC-RC vertical composite frame is increased from 3-5 layers to 4-6 layers,the average ductility coefficient of the structure increases by 2.44%,indicating that the deformation capacity of the structure is improved;more plastic hinges can appear in the vertical hybrid frame structure models to absorb energy which seldom occurred earthquake action released before the structure is destroyed.So SRC-RC vertical hybrid frame structure with good ductility is able to withstand the rare earthquake and does not collapse.关键词
