摘要
文章以古龙大桥主桥(85+160+85m连续刚构)为研究对象,采用MIDAS/Civil有限元软件对其动力特性进行分析,得出成桥状态下结构的自振特性,并采用反应谱法和时程分析法分别计算E1地震作用下与E2地震作用下桥梁结构的受力与位移情况,分析其抗震性能。
With Gulong Bridge (85 + 160 + 85m continuous rigid frame) as the research ob- ject,the article used the MIDAS/Civil finite element software to analyze its dynamic characteristics,obtained the self-vibration characteristics of its structure under the state of comple- ted bridge,meanwhile the article used the response spectrum method and time history anal- ysis method to calculate the force and displacement situation of bridge structures under the role of E1 earthquake and E2 earthquake,and also analyzed its anti-seismic performance.
