高层钢框架P-⊿效应的简化计算

Simplified Calculation of P-Δ Effects in Highrise Steel Frames

本文提出的简化计算法是在剪力分配新法的基础上发展而成的,计算十分方便。文中通过算例与精确法进行了比较,其结果是令人满意的。

This paper presents a simplified method for calculating the P-Δ effects in highrise steel frames, which is developed from the new shear distribution method given in reference [1]. Numerical examples are illustrated. The results obtained from the proposed method are quite satisfactory as compared with those by the more precise method.
