摘要
Abstract
This article takes the railway bridge as an engineering background, using finite element software to establish dynamic model. Analysis of P -△ effect of railway bridge with high-rise piers under the action of vertical earthquake. The results of the study show that due to the influence of nonlinear, the action of vertical earthquake strengthened the influence of horizontal earthquake reaction considering the action of vertical earth- quake and effect of P -△effect. Provide a reference for Aseismic optimum design of this bridge.关键词
