Abstract

Abstract: The linear and nonlinear time history seismic response of an irregular continuous bridge with the same span was analyzed by fiber model method; the impact of Peffect on seismic response of the bridge and differences between linear and nonlinear results were analyzed.The results showed that the short pier with higher stiffness was weak in earthquake resistance and it could be severely damaged in earthquake; the impact of Peffect on the short pier was insignificart; linear results were different from nonlinear results.

Key words: irregular continuous bridge, linear, nonlinear, seismic response, Peffect

摘要： 采用纤维模型分析方法,对一座墩高差异较大的非规则等跨连续梁桥进行了全桥的线性和非线性时程地震反应分析,并比较了P-效应对该桥地震反应的影响以及线性与非线性结果的差异。分析结果表明:对于这类桥墩刚度差异较大的连续梁桥,刚度较大的矮墩是其抗震的薄弱部位,地震中损伤相对较严重；墩高较小时,P-效应对分析结果的影响较小,线性与非线性分析结果之间差异较大。
