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进行了数值模拟,并利用反应谱分析法分析了高墩大跨连续刚构桥在不同作用方向地震波作用下的内力变化,从而为刚构桥的抗震设计奠定了基础。
Applying large scale structural analysis program Midas/Civil, this paper carries on numerical simulation on the earthquake response of an actual long-span rigid frame bridge with high piers, and analyzes the internal force change of the long-span rigid frame bridge with high piers under the earthquake wave at various action directions. Thus, it has laid a foundation for aseismatic design of the rigid frame bridge.
