摘要
选取飞燕式桁架拱桥为研究对象,利用大型有限元分析软件建立全桥模型,分别基于89规范和08细则中各项规定进行计算、分析和比较。结果表明新、旧抗震规范进行抗震计算结果出入较大,新抗震规范安全保障性更高。
A flying swallow type arch bridge is selected as research object in this paper. A FEM software is used to establish a modal of the whole bridge. Calculation and comparation is done based on the 2008 and 1989 seismic code separately. The results show a big difference between the two codes, and the new one provides a better security.
