摘要
运用ANSYS二次开发功能参数化建模,分析研究拱肋横撑、拱肋倾角、桥墩刚度、拱肋矢跨比等设计指标对下承式刚架系杆拱桥的动力性能与地震响应性能的影响,总结下承式刚架系杆拱拱桥的动力学变化规律及地震响应变化规律。
Using the secondary development of ansys, the paper analyzed the influence of arch bracing, arch slope angle, pier rigidity, ratio of rise to span and so on on the dynamic properties and seismic reaction properties of arch bridges made of concrete-filled steel tube and summarized the change rules.
