摘要
制作了1个无填充墙的现浇混凝土联肢剪力墙试件和1个带填充墙的装配式混凝土联肢剪力墙试件,对两个试件进行低周反复荷载试验。通过观察各模型的破坏形态并对比分析它们的滞回曲线、骨架曲线、刚度退化曲线、延性及耗能能力等,综合评价填充墙对装配式联肢剪力墙抗震性能的影响。结果表明:现浇混凝土联肢剪力墙试件的破坏形态为连梁部位的剪切破坏和墙肢部位的弯剪破坏,而带填充墙的装配式混凝土联肢剪力墙试件的破坏形态则为墙肢部位及填充墙部位的剪切破坏;带填充墙的装配式混凝土联肢剪力墙试件的刚度、承载力和耗能能力均高于无填充墙的现浇混凝土联肢剪力墙试件,其延性稍差于现浇混凝土联肢剪力墙试件。基于本次试验结果,建议在装配式混凝土联肢剪力墙结构设计中,应适当考虑填充墙对主体结构承载力与刚度性能的影响。
Quasi-static tests were carried out on a cast-in-place coupled shear wall and a prefabricated coupled shear wall with infill wall. Their failure modes were observed and hysteresis curves,skeleton curves,stiffness degradation curves,ductility and energy-dissipation capacity were analyzed to assess the effects of infill wall on coupled shear walls on seismic performance. Results showed that shear failure on coupling beams and bending-shear failure on wall limbs were the main failure mode of cast-in-place coupled shear walls. The failure mode of prefabricated coupled shear wall with the infill wall was shear failure on wall limbs. The stiffness,bearing capacity,and energy-dissipation capacity of prefabricated coupled shear wall were higher than that of the cast-in-place specimen. The ductility of prefabricated coupled shear wall was lower than that of cast-in-place specimen. Based on the test results,it was suggested that the influence of the infill wall on the bearing capacity and stiffness of the main structure should be considered in the design of prefabricated concrete shear wall structure.
