摘要：

Cyclic loading tests of six steel high strength concrete (SHRC) shear walls with shear span ratios of 2.1, 1.5 and 1.0 were conducted and the failure patterns of the shear walls under different aspect ratios was studied. On the basis of the damage levels of SHRC shear walls, the limit state of the different seismic performance levels and their dominating parameters are proposed. The performance of SHRC shear walls can be divided into four levels, performance continuity, performance interruption, life safety and collapse prevention. The story drift ratio of SHRC shear walls are developed for four different seismic performance levels and the ultimate drift ratio are calculated using numerical method. Comparison between calculation results and test results illustrates that those calculating procedure is feasible. A performance-based deformation capacity design method was developed for SHRC shear walls and the transverse reinforcement characteristic value in accordance with the target top displacement ratio and axial load ratio was proposed.
