建立三维桥梁计算模型,运用大型计算软件,分别采用反应谱法、时程分析法分析桥梁各关键部位的内力、位移,以了解掌握该类桥在地震响应中的结构特性和受力行为。
The calculation model of three-dimensional bridge is established. The large-scale calculation software is used to analyze the internal forces and displacements of the key parts of the bridge by response spectrum method and time-history analysis respectively to understand the structural characteristics and stress behavior of such bridges in seismic response.
