| 摘 要： | 运用大型结构分析程序Midas/civil在地震波作用下,对某一实际高墩大跨连续刚构桥的地震反应的行波效应进行了时程分析的数值模拟,分析了高墩大跨连续桥在顺桥向地震波作用下不同的相位差的行波效应,以及行波效应对桥梁高低墩墩差产生的影响.结果表明:行波效应对高墩大跨连续桥的影响很大,桥梁高低墩墩差越大行波效应越明显,高墩大跨连续桥在抗震设计时应考虑行波效应.

| Abstract: | By using large-scale structural analysis program Midas/civil,under the action of seismic waves,time-history analysis of the numerical simulation is imposed on the travelling wave effect of seismic response of a real high-pier-span continuous rigid frame bridge.Analysis is about the travelling wave effect of different phase of high-span continuous bridge pier under the action of the seismic waves parallel with the bridge,as well as different impact of the travelling-wave effect on the height difference of br... |
