摘要
以预应力简支T梁桥为对象,建立了实体单元有限元模型,在对称和偏载作用下分别计算了有无横梁情况时的响应并进行了比较分析,结果说明中横梁对大桥受力状态特别是翼缘板的受力状态有较大的作用。根据这一结论,对该桥主要采取了增加跨中横隔梁的加固措施。
Based on T-girder bridge,the space solid FEA model is established in an aim to calculate and compare the response of the structure in asymmetrical loading and symmetry loading with the diaphragm or without the diaphragm.It shows that the diaphragm improve the bridge mechanical performance,especially for the wing plane.With the conclusion, diaphragms were added as one of the strengthening measures.
