摘　　要：基于框架结构剪切型变形的特点 ,将框架结构等效为层间剪切模型 ,导出一种框架结构二阶效应的实用算法 .算例表明其计算误差较小 ,使用简便 ,可满足工程设计计算的精度要求 .Based on the charactercstic of shear deformation of a frame structure, the author makes the frame structure equivalent to an interlayer shear model, and derives a practical algorithm for second-order effect of a frame stracture. As shows by example of calculation, it is a handy method with small error of calculation, It can be met with the demand of accuracy in calculation of engineering design, It is suitable for use in high-rise frame structure of reinforced concrete and also steel frame.
