【摘要】 普通钢筋混凝土剪力墙结构在地震作用下延性较差,裂缝开展及破坏部位集中,其抗震性能不甚理想。基于结构被动控制的概念提出的耗能剪力墙结构体系具有较好的延性和耗能能力,可较为显著地改善剪力墙结构在地震作用下的性能,国内外诸多学者均对其进行了研究。简述了耗能剪力墙的减震机理,介绍了几类有代表性的耗能剪力墙结构体系,包括带缝剪力墙、耗能连梁剪力墙、组合填充耗能剪力墙及摇摆耗能剪力墙等,概述了其构造、试验研究及计算分析概况,并指出了耗能剪力墙体系研究和应用中的不足之处。更多还原

【Abstract】 The seismic behavior of shear wall structures is not very good due to poor ductility and concentration of crack spreading and even failure.Based on the concept of passive structural control,a variety of seismic energy-dissipation shear wall systems with good ductility and energy dissipation ability have been proposed and studied at home and abroad to make improvement to the behavior of shear wall structures under earthquakes.The damping mechanism of energy-dissipation shear wall systems is outlined.Several typical shear wall systems utilizing proposed mechanism,including slit shear walls,coupled shear walls with damping beams,hybrid infilled walls,rocking walls et al,are introduced in constructional details,experimental studies,and analyses of the systems.The limitions in previous researches and applications are also included in this paper.更多还原
