摘要
通过模态分析和时程分析研究了索拱结构的动力性能和地震响应。分析中改变矢跨比和预应力对比索拱相对与拱的动力性能的变化。在地震响应中考虑索拱的非线性,分别分析了索拱和拱对水平和竖向地震的响应。
In this paper,the dynamic characteristics and seism response of cable-arch were analyzed with mode and time-course analysis methods.Through changing rise-span ratio and prestress.The characteristic of cable-arch was compared with cablel arch.Nonlinear was considered in processing of seism response and the seism response of cable-arch causing of vertical earthquake load and level earthquake load were analyzed.
