摘要
基于非线性连续介质力学理论（有限变形理论）的一般原理，推导出精确计算平面钢框架结构二阶效应的非线性刚度方程，分析中还计及了剪切变形的影响．计算结果表明．对于多层及高层银框架结构，二阶效应及剪切变形的影响不应忽略．
Based on the general principle of virtual displacement of nonlinear continuum mechanics. The se cond order effect and the influence of shear deformation of plane frames is anslyzed. The numerical examples show that the second order effect and the influence fo shear deformation should be taken into account in the analysis of multistory frames.
