摘要
将普通钢支撑和屈曲约束钢板剪力墙引入到束柱中,并选择2层的平面钢束柱,对比研究了不同支撑布置方式以及不同钢板剪力墙尺寸下束柱的承载力、抗侧刚度和延性。结果表明:钢支撑束柱的抗侧性能与支撑的数量及长细比密切相关;屈曲约束钢板剪力墙能够为束柱提供很大的抗侧刚度,同时也承担了绝大部分层间剪力;在相同缩进高度下,增加钢板剪力墙的缩进宽度对束柱抗侧性能的提升效果明显。
Steel brace and buckling restrained steel plate shear wall （BRSPSW） were introduced into the bound-column, and comparison analyses were performed in different arrangements of steel braces and various BRSPSW sizes, based on a two story steel bound column frame. Load bearing capacity, stiffness and ductility of structure were taking into consideration. Results show that the lateral resistant performance of steel brace bound column has intimate relationship with the number and slenderness ratio of steel brace. BRSPSW not only provides huge amount of stiffness for BRSPSW-steel bound-column, but also absorbs large proportion of story shear force. Besides, widening the retraction width of BRSPSW will remarkably enhance the lateral resistant performance of steel bound column, in the condition of the same retraction height.
