高层组合框架P-Δ效应的差分计算
Difference Calculation of P-Δ Effects in High Composite Frames
【摘要】 高层组合框架在进行侧移计算时,由于其柱截面尺寸较小,应考虑其几何非线性的P—△效应的计算。本文提出了差分方法的简化方法,并与微分方法计算过程和结果进行了比较,结果说明该方法计算简捷明了,满足精度要求。
【Abstract】 A simplified difference method for calculating the P-Δ effects in high composite frames is presented in this paper. The effectiveness of the method is presented through comparison with the results of differential method.
