| 中文摘要: |
| 在考虑支座摩擦刚度基础上分析了梁拱组合体系桥的动力特性，分别采用反应谱法和时程分析法对某连续梁拱组合桥进行了抗震分析。反应谱法分析基于线性系统，而时程法作为精细的分析方法，考虑了边界非线性问题，因而更能反应结构在地震时的实际反应情况。对比分析结果对工程抗震设计具有指导意义。 |
| 英文摘要: |
| The dynamic behavior of the bridge is analyzed with the friction stiffness of the bearing taken into account, and the anti seismic behavior of arch beam combination system of rigid frame bridge is analyzed using the response spectrum method and the time history analysis method. Because the response spectrum method is based on the line system, and the time history analysis method is based on the nonlinear system and the time history analysis method has considered the nonlinear problem of the border, so the time history analysis method better reflects the actual situation of the bridge when earthquake. Some useful conclusions on the project anti seismic designing are put forward by means of analysis and comparison. |
