框-剪结构的二阶分析

本文采用连续化方法对框-剪结构进行二阶分析。本文考虑框架柱子轴向变形的影响和剪力墙之间连梁的作用。首先推导了一组基本微分方程。然后采用有限积分法对其进行数值求解。 本文所给出的方法也可以用来求框-剪结构侧向失稳的临界荷载和对框-剪结构进行一阶分析。另外,剪力墙结构也可以当作是框-剪结构的一种特殊情形来加以分析。

Second Order Analysis of Wall Frame Structure

Based on the continuum approach, a second order analysis of wall-frame structure is presented in this paper. The effect of axial deformation of columns and bending stiffness of connecting beams are taken into account. A set of differential equations are derived at first, and then solved by the finite integration method.The proposed technique can also be used to determine the lateral buckling loads of wall-frame structures and it can be used as an efficient method for the first order analysis. Furthermore, shear wall structure can be treated as a special case of wall-frame structures.
