某钢筋混凝土简支梁桥静动载试验研究

介绍了某简支梁桥静动载试验的主要内容和方法,并将荷载试验中桥梁结构的实测应力、挠度及振动特性进行了分析,试验结果表明该桥主梁已经存在损伤,梁间横向联系明显减弱,需进行维修加固,研究结果可为同类型桥梁的设计和成桥试验提供参考。

Static and Dynamic Load Test Research of A Reinforced Concrete Simply Supported Girder Bridge

Main content and methods of static and dynamic load test on a simply supported girder bridge are introduced and actual measured stress,deflection and vibration performance of bridge structure during load test are analyzed.The test result shows that the girder of the bridge has been damaged and horizontal linkages among girders are weakened greatly which needs maintenance for strengthening.The research result could provide references for design of similar bridge and test on similar completed bridge.
