摘要
改变三种不同形式的转换梁刚度,分析转换梁及其上部剪力墙的内力变化,通过平面高精度有限元分析发现,减少转换梁的刚度,转换梁与其上部剪力墙的共同工作能力进一步强化,上部剪力墙更多地参与抵抗外力,同时转换梁的内力发生变化,转换梁刚度对框支剪力墙的受力性能有较大影响,这些结论可为此类结构设计提供参考。
By change three different forms of transfer beam stiffness,the paper analysis the internal force change of transfer beam and upper shear wall.Through the finite element analysis it is found：throug weakening of stiff ness of transfer beam the ability of thransfer beam work together with the upper shear wall becomes more strengthen,the upper shear wall more involved resistance forces,the internal force of transfer beams becomes change.The conclusion about the stiffness of transfer beam is more impact on framed shear wall can provide reference for such structure design.
