摘要
本文利用大型结构分析程序MSC/NASTRAN对地震波三向正交分量分别独立作用和联合作用下斜拉桥的地震反应的行波效应进行了数值模拟,分析了斜拉桥地震反应在各向振动分量作用、以及不同相位差和不同结构约束条件下的行波效应,对其一般影响规律进行了讨论.
The advanced finite clement analysis program MSC/NASTRAN has been successfully used in this paper for numerical simulation of seismic response of cable-stayed bridges to travelling wave excitation from three dimensional orthogonal components acting individually or jointly. The effects of travelling wave in different direction on the response and the effects of travelling wave with different phase lag and different deck connections on the response are studied. The general influence of travelling wave is then obtained.
