Abstract
Numerical models of two steel-concrete composite shear walls,one with steel truss and the other with steel plate were verified firstly.Then the two shear walls with the same steel ratio were analyzed under cyclic load.The load carrying capacity,stiffness,degradation of strength and stiffness,ductility,energy dissipation characteristics and hysteresis characteristics of the two walls were compared.The seismic performance of structures with two steel-concrete composite shear walls were compared.The result proves that,at component level,with the increase of the aspect ratio,the bearing capacity,ductility and energy-dissipating capacity of steel plate RC shear wall gradually become stronger than RC shear wall with steel truss in the case of same steel ratio.At the structure level,when the aspect ratio is big,the seismic performance of structure with steel plate reinforced concrete shear wall is better than the structure with steel truss RC shear wall.
