| 摘 要： | 文章以某40m预应力混凝土简支T梁为例，利用单轴车桥耦合振动数值模型及基于MidasCivil的简易车桥耦合振动模型对移动车辆荷载作用下的T梁结构动力响应情况进行计算分析。结果表明，基于MidasCivil的简易车桥耦合振动模型与数值模型的结构挠度峰值计算结果相差不大，可用于简单的车桥耦合振动分析。

| Abstract: | Taking a 40-meter simply supported T-shape beam in pre-stressed concrete as an example,and by using single axis vehicle-bridge coupled vibration numerical model and simple vehicle-bridge coupled vibrations based on Midas Civil,the article made calculation-based analysis of the T-shape beam structural dynamic response under the impact of moving vehicle load.lt is proved that simple vehicle-bridge coupled vibration model based on Midas Civil does not differ from numerical model to a large extent in terms of structural deflection peak,and thus it can be used for analyzing simple vehicle-bridge coupled vibration. |
