开洞式组合钢板剪力墙构造及耗能能力研究
|
摘要
提出了一种适用于小高层建筑的新型开洞式组合钢板剪力墙结构形式.该结构体系包括三边固结约束、一边弹性约束的钢板-预制水泥基轻型墙板组合剪力墙,实腹式T形组合柱,不等翼缘钢连梁3个基本单元.针对采用3种不同构造形式的组合钢板剪力墙结构体系进行了试验研究,分别考察了3种组合钢板剪力墙形式对框架结构的延性性能和耗能能力的影响及各自的破坏特征和受力机理.结果表明:采用角钢和预制水泥基轻型墙板共同防止钢板面外屈曲的组合剪力墙形式能够充分发挥钢板剪力墙的材料塑性,改善结构体系的抗震性能和耗能能力,较纯框架而言抗侧刚度提高90%,延性提高47%.文中还针对预制水泥基轻型墙板的破坏特征、钢板剪力墙与边缘框架连接形式及连接破坏特征进行了相关讨论.
This paper describes a novel composite shear wall system for use in high-rise building construction.The system includes three elements: A composite,precast light weight concrete steel plate shear wall under trilateral constraint;A set of "T" shaped solid web composite columns;And,coupling beams with unequal width flanges.Various buckling restrained designs of the steel plate composite walls were investigated experimentally to determine their structural capacity.Restraint was provided by either angle iron restraints,precast plate restraints,or composite steel-concrete restraints.The failure mode of the steel plate composite walls was determined.The results showed that the composite restraint takes full advantage of the steel material capabilities.The lateral stiffness moment increased 90 percent for this composite shear wall.The capacity of the structure for energy dissipation was increased 47 percent.The failure modes of the precast plate and bolt connected plate designs are discussed and some useful conclusions are presented.
