全装配式L形截面双面叠合剪力墙抗震性能试验研究
Experimental study on seismic behavior of fully assembled L-shaped section double-sided composite shear wall
摘要
Abstract
The traditional prefabricated L-shaped double-sided composite shear wall(DSW)is made by prefabricating double-sided composite wall panels in the factory and cast-in-place L-shaped section boundary components,which results in low construction efficiency and insufficient ductility.Therefore,a fully assembled L-shaped section double-sided composite shear wall with prefabricated boundary components(FDSW)was developed.By conducting full-scale quasi-static tests on two FDSW specimens,two cast-in-place shear walls(RCW)and one DSW comparison specimens(n is 0.1 and 0.3),the effects of axial compression ratio,joints,corrugated pipes on the seismic performance of FDSW were studied.The results indicate that the FDSW failure mode is mainly horizontal joint and vertical joint failure.As the axial compression ratio increases,the tensile failure of FDSW horizontal joints decreases and the shear failure of vertical joints increase.Under high axial compression ratio(n is 0.3),due to the effective constrain the concrete deformation of the boundary components of edge components by corrugated pipes,the bearing capacity and deformation capacity of edge components are improved.The degree of damage of edge components in FDSW is significantly lower than that in RCW and DSW,and the hysteresis curve is full without pinching effect.Compared to RCW,FDSW has an increased loading capacity of 8.1％to 11.2％,a 49.6％increase in total energy consumption,and a 28.3％increase in ductility coefficient,indicating good seismic performance.关键词
