摘要
提出使用压型钢板组成剪力墙,对钢筋混凝土框架进行框剪抗震加固的方法,并对压型钢板剪力墙的抗剪性能进行有限元分析。结果表明,压型钢板板条间连接的剪力墙具有较好的整体性,抗剪延性好,可充分耗能;压型钢板沿肋向受压的剪力墙会发生面外鼓曲失稳破坏,其抗剪稳定承载力远小于沿肋向受拉时的承载力。对板材不同布置方案的极限抗剪承载力进行对比分析可知,压型钢板斜向45°布置且相邻板材连接时抗剪承载力性能最佳。
A measure for seismic strengthening of reinforced concrete frame with shear wall composed of profiled steel sheeting is proposed. Behavior of shear wall composed of profiled steel sheeting is analyzed in finite element method. Shear walls with profiled steel sheeting fastened mutually have better integrity, high ductility and good energy-dissipation. Shear wall with profiled steel sheeting in compression along ribs has out-of-plane destabilization failure mode, and its shear bearing capacity is much less than shear wall with sheets in tension along ribs. Through comparative study of different layout schemes of profiled steel sheeting, the scheme that profiled steel sheeting inclined at an angle of 45° and fastened mutually has the best performance of shear capacity.
