| 摘 要： | 铁路提速易导致既有钢板梁的振幅超限。针对钢板梁的谐振,利用SAP2000对24m钢板梁的不同加固方案(包括下平纵联加固、横联加固和将简支梁在端部连接起来变成连续梁的方法)进行了建模对比计算。通过计算比较,得出连续化的加固减振方案效果较好。

| Abstract: | Displacement is liable to exceed the limit because of the raising of train speed. In the light of the resonance of steel plate girder bridges, the modeling and calculating with different reinforcing methods(reinforcing the top bracing, the bottom bracing, the sway bracing and making the simple beams continuous at beam end)for 24m-steel plate girder bridge are performed by means of Sap2000 in the paper. Through calculation and comparison, the effect of making the simple beams continuous is found better than that of other methods. |
