混凝土砌块砌体剪力墙的抗震性能(抗剪承载力、延性、耗能能力等)对混凝土砌块砌体剪力墙结构(以下简称砌块砌体结构)的发展有着重要的意义。为研究砌块砌体剪力墙的抗震性能,对2000年以来配筋和约束砌块砌体剪力墙的研究成果进行分析与总结,主要得到以下结论:对于配筋砌块砌体剪力墙,提高竖向钢筋配筋率可以提升墙体抗剪承载力,竖向钢筋间距和布置方式对抗剪承载力和延性等影响很小;水平配筋可以有效地改善墙体的整体性;提高轴压比可以增加抗剪承载力,但是会降低延性;设置边缘构件可以提高墙体的抗剪承载力和延性。对于约束砌块砌体剪力墙,芯柱和构造柱都可以提升墙体的抗剪承载力和延性,构造柱-芯柱体系结合了构造柱和芯柱的优点,可以更有效地提高墙体的抗震能力。
The seismic performance of concrete block masonry shear walls (shear capacity, ductility, energy dissipation capacity, etc.) is of great significance to the development of concrete block masonry shear wall structures (hereinafter referred to as block masonry structures). In order to study the seismic performance of block masonry shear walls, the research results of reinforced and bound masonry shear walls since 2000 are analyzed and summarized. The main conclusions are as follows: For reinforced masonry shear Wall, increasing the vertical reinforcement ratio can enhance the shear strength of the wall, vertical reinforcement spacing and arrangement of shear strength and ductility and other small impact; horizontal reinforcement can effectively improve the integrity of the wall; Increasing the axial compression ratio can increase the shear capacity, but will reduce the ductility; setting the edge member can improve the wall shear capacity and ductility. For the constrained block masonry shear walls, both the core columns and the structural columns can enhance the shear strength and ductility of the wall, and the structural column-core column system combines the advantages of the structural column and the core column to effectively improve the wall Seismic capacity of the body.
