摘要:
为研究得到带暗支撑的预制叠合板剪力墙合理的竖向连接方法,分别设计了1片带钢板暗支撑的局部高阻尼混凝土U型连接预制叠合剪力墙和1片带90°钢板暗支撑的局部高阻尼混凝土预制叠合剪力墙,并设计1片普通钢板暗支撑现浇剪力墙做对比,进行了拟静力试验研究,对比三个试件在受力作用下的承载能力、滞回曲线、骨架曲线、位移延性、刚度退化、耗能性能、裂缝发展情况以及破坏形态。研究结果表明:采用U型连接的带暗支撑预制叠合板剪力墙与现浇带暗支撑剪力墙的承载能力以及抗震性能基本相近,90°暗支撑的预制叠合板剪力墙在减少钢材用量的前提下也拥有足够的承载能力和良好的抗震性能。
Abstract:
In order to obtain the reasonable method of vertical connection of precast composite shear wall with concealed steel plate bracing, one piece of local high damping concrete precast composite shear wall with the U-shaped vertical connection and one piece of local high damping concrete precast composite shear wall with the 90° angle steel plate were designed respectively. Quasi-static tests of the two pieces of precast composite shear wall and one piece of cast-in-situ shear wall with steel plate bracing were carried out.Bearing capacity, hysteretic curves, skeleton curves, displacement ductility, stiffness degradation, energy-dissipation ability, crack development and failure pattern were obtained and compared.The test results show that seismic performance of precast composite shear wall with the U-shaped vertical connection and the cast-in-situ shear wall with steel plate bracing are nearly the same, concrete precast composite shear wall with the 90° angle steel plate also has good seismic performance and can reduce usage amount of steel.
