The Hysteretic Performance Study Of Ribbed Low Yield Point Steel Shear Wall

Ribbed low yield point steel plate shear wall is a new kind of structure to resist lateral force.In this paper two ribbed type low yield point steel plate shear walls has carried on the experiment and theory research,the main research contents are as follows:(1)By two ribbed type low yield point steel shear walls 1:2 scale model of simulation static test research,study the ribbed type of low yield point steel plate shear wall’ bearing capacity,stiffness,ductility,energy dissipation capacity,discusses the hysteretic performance of this new type wall panel,the energy dissipation mechanism and failure mode.Experimental results show that ribbed type low yield point steel shear wall is a kind of seismic performance superior component to resist lateral force.(2)Adopting the finite element program ABAQUS,the simulation analysis of the two ribbed type of low yield point steel plate shear wall’s under horizontal reciprocating load bearing performance.And compared with the test results,the results show that the finite element simulation of stress component development process and failure mode phenomena are basically identical with the experiment,and the finite element calculation of load-displacement curve was consistent with the test result.In order to further provide the basis for the finite element analysis.(3)Using SAP2000 analysis the steel frame-ribbed type low yield point steel plate sh ear wall structure seismic response,contr ast analysis of the different forms of ribbed type low yield point steel shear wall with frame structure damping effect of energy consumption.Analysis results show that this new type of shear wall is a kind of good resistance to lateral force.
