| 中文摘要: |
| 根据《公路桥梁抗震设计细则》(JTG／T B02—01—2008)中的抗震设防新理念和新方法，以Ⅶ度区某连续梁桥为工程背景，建立了弹塑性有限元模型，依次进行了动力特性分析、地震反应谱分析和非线性时程分析，揭示了两级地震作用下桥梁的受力及变形情况，并对桥梁的抗震性能进行了评价，可供桥梁抗震设计参考。 |
| 英文摘要: |
| According to the new ideas and new methods by guidelines for seismic design of highway bridges (JTG / T B02—01—2008), with the background of a continuous girder bridge in the area of 7 degree earthquake intensity, an elastic plastic finite element model is established for dynamic characteristics analysis, seismic response spectrum analysis and nonlinear time history analysis, to reveal the force and deformation under earthquake action of two levels. Furthermore, the seismic performance is evaluated to provide a reference for seismic design of bridges. |
