To improve the seismic behavior of high performance concrete shear wall(HPCW),a new stirrup arrangement of independent closed reinforcement hoops nested with each other in six HPCWs with edge columns was developed,and verified by the pseudo-static test.Aspect ratios of walls are 1~2,and axial load ratios 0.28 ~0.40.The cubic compressive strength of concrete is 89~99 MPa for different specimens.The ultimate strength of stirrup is 737.5 MPa.Development of cracks and failure modes of specimens were compared.Hysteretic characteristics,load-bearings,deformation-ability,and rigid attenuation,strain of reinforcement were analyzed.The displacement ductile ratios measured were 3.75~5.20,the coefficients of energy dissipation were 0.76~1.31.Results showed that the new stirrup arrangement effectively improved the seismic behavior of the HPSW with edge columns such as ductility,deformability,energy dissipation capacity etc.Based on results,allowable values of drift angle and rotation of plastic hinge for four performance levels of shear wall components were presented.
