摘要

An slitted shear wall combined with keep-warming layers and dissipating energy forms, is represented in this paper. This new type shear wall has multi seismic resistant system. Based on the advantages of the new type of shear wall, six model specimens were designed and fabricated. By cyclic reversed loading test, the structural dynamic performances such as internal force, deformation behavior, energy-dissipating mechanism and failure proceeding of the specimens, under the different ratio of axial compressive force and connecter forms have been investigated. It is shown that to set the vertical slit and connects on the wall can effectively affect the seismic behavior of shear wall structure. If setting the vertical slit and connects reasonably, the seismic and deformation behavior of shear wall can be improved greatly, with the bearing capacity is reduced a little degree. The results show that the new type wall showing a bend ductility of shear damage and failure mechanism of change because of its ductility and deformation capacity be improved.
