摘要
以标准跨径的两跨公路连续混凝土斜交桥为研究对象,建立动力有限元计算模型,分别进行了常遇地震影响下的反应谱分析和罕遇地震影响下的非线性时程分析,探讨了斜交角变化对连续斜交桥地震反应的影响,并得到了影响规律。
Numerical models for the continuous skew girder highway bridges with standard span are set up in this paper. Response spectrum analysis under the frequently occurred earthquake ground motion and nonlinear time - history analysis under the seldomly occurred earthquake ground motion are employed to investigate the influence of skew angle on the seismic response of the bridges, respectively. The effect rules are drawn from the analysis.
