In order to study the seismic performance of reinforced concrete energy dissipation wall and its shock absorption effect on the bottom flexible building,three energy dissipation walls were designed,and the design parameters were section size,the arrangement of the wall and the form of reinforcement.The failure characteristics,hysteretic energy dissipation,displacement ductility and stiffness degradation of three specimens were studied by low-cycle reciprocating loading tests.Seven near-field seismic waves and eight far-field seismic waves were selected,and SAP2000 finite element software was used to analyze the seismic response of the bottom flexible structure with energy dissipation walls.The results showed that the three energy dissipation walls had good seismic performance,and the deformation capacity as well as energy dissipation capacity of the wall could be improved by setting a vertical slit on the wall body.The internal steel plate had obvious effect on improving the seismic energy dissipation performance of the energy dissipation wall.Under the action of near-field and far-field earthquake,after adding energy dissipation wall the average displacement angle of the first floor decreased by 21.7% and 17.6%,respectively,and the average shearing force between floors decreased by 16.3% and 18.1%,respectively.The energy dissipation wall could improve the seismic capacity of the structure,significantly reduce the hysteretic energy consumption of the main frame,and reduce the seismic response of the structure.
