摘要
应用MSCPatran建立铁路钢桥的3D有限元计算模型,运用MSCNastran进行桥梁自振特性计算和地震响应分析,旨在探究桥梁结构在高烈度地震作用下的响应规律.
The dynamic characteristics and seismic response of railway steel truss bridge is calculated by MSC Nastran with a 3D model constructed by MSC Patran, The seismic response rule of the railway steel truss is studied under the high intensity earthquake.
