摘要
本文提出了高墩在进行结构性能分析和验算时,计算P-Δ效应引起的内力和变形的重要性,介绍了考虑p-Δ效应的桥墩计算原理与方法,并通过应用桥梁分析软件Midas中P-Delta分析过程对实际墩荷载进行计算分析,得出桥墩在考虑p-Δ效应时的荷载效应(墩顶位移、墩底弯矩等)比不考虑p-Δ效应时的大,且其增大率一般随墩高的增大而增加的规律。
The importance of calculating the internal force and deformation caused by the P-Δ effect is pointed out when analyzing and checking the structural performance of the high pier and the calcaulating principle and method of the pier considering the P-Δeffect are introduced in this article。What's more, through the study of the practical pier load calculated by the P-Δeffect analysis process of the Midas software, the rules are obtained that the load effect on the pier is higher when taking the p-Δ effect into account and the increasing rate of which generally increases with the pier height increasing.
