摘要:
提出一种新型竖缝耗能预制剪力墙结构,对偏心设置竖向缝的耗能预制剪力墙试件进行低周往复加载试验,分析研究试件的刚度退化、承载力、破坏形态、耗能能力以及延性等力学性能,并将试验结果与现浇剪力墙的试验结果进行对比分析.结果表明:偏心竖缝耗能剪力墙与现浇剪力墙表现为弯剪破坏; 与现浇整体剪力墙试件对比,偏心竖缝耗能剪力墙的刚度与承载力相差不大,延性和耗能能力较好,变形能力得到改善.偏心竖缝耗能预制剪力墙具有很好的抗震性能.
Abstract:
A type of prefabricated energy-dissipating shear wall specimen with eccentric vertical joints was designed and low-cycle reciprocating loading test was carried out to analyze the stiffness degradation, bearing capacity, failure form, energy-dissipating capacity and ductility of the specimen, and the test results were compared with the cast-in-place shear wall specimen.Results show that the eccentric vertical joint energy dissipation shear wall and cast-in-place shear wall are characterized by destruction of the bending. The stiffness and bearing capacity of the energy-dissipating shear wall with eccentric vertical joint are similar to the cast-in-place shear wall specimen, but the ductility and energy-dissipating capacity are better. The deformation capacity of the energy-dissipating prefabricated shear wall with eccentric vertical joint has good seismic performance.
