P-Δ效应计算新法

摘要

In contrast to iterative calculating method, a new method of calculating the P-Δ effect was set up by reversed analysing of displacement. This method is simple and convenient. The calculating results are more accurate than that of iteration method through actual example.%针对当前人们在结构计算中较多采用迭代方法来近似考虑P-Δ效应的影响，用位移反分析的方法推导出一种无需迭代来计算P-Δ效应影响的简便、实用计算方法。算例表明该方法的计算结果是原迭代法的准确值。
