| 摘 要： | 利用ANSYS有限元程序建立其计算模型,基于大跨度桥梁的抗震设计理论,考虑了材料非线性及多点激励效应等因素,运用时程分析法对某中承式大跨度钢拱桥进行了罕遇地震作用下的地震响应分析,得出行波效应对大跨度拱桥截面的内力影响显著,对总体来说是不利的,不能忽略。

| Abstract: | The paper adopts the finite element program, ANSYS, to establish its calculating model, considers the factors, such as the nonlinear and multiple excitations of the materials and others, based on the anti-seismic design theory of the large-span bridge, applies the time history a- nalysis method to undertakes the earthquake response analysis of the half-through large-span steel arch bridge, and concludes the influence of the travelling wave effect on the internal force of the large-span arch bridge section, so its unfavorable influence can not be neglected. |
