钢骨混凝土转换梁的受力分析

Stress Analysis of SRC Transfer Beams

利用解析方法分析钢骨混凝土转换梁与上部剪力墙共同作用的受力特点和变形规律,得出这种结构的应力分布解析解,并与某工程的非线性有限元计算数据进行比较,结果是吻合的。转换梁应作为偏心受拉构件,同时要考虑剪力墙参与工作部分。在剪力墙和转换梁端部应着重考虑剪力与竖向压应力,并考虑二者共同作用。

The structural behavior of steel reinforced concrete(SRC) transfer beam and upper shear wall in cooperation is studied with the elastic mechanics method and the nonlinear finite element method.The results show that the beam can be an eccentric tension member,meanwhile the performance of shear wall must be considered.Results also show that at the end of the transfer beam and the shear wall,special consideration must be given to the shear stress and vertical compressed stress,and the interaction between them.
