Assessment of bridge capacity through proof load testing
ABSTRACT: Aging is a matter of increasing concern for most bridges that are part of the road and railwaysystems of the European Union. Many of these bridges are very old bridges without documentation. A possibleway to assess their capacity is by means of a proof load test.Two main questions should be solved when facing the execution of such a test: a) Which is the load levelthat the bridge should resist during the proof test to guarantee a predetermined service load with a required andappropriate safety level? and b) When the increase of loading should stop in order to not damage the structure?The answer to these questions is part of the task of the EC 6th Framework Programme European ProjectARCHES (Assessment and Rehabilitation of Central European Highway Structures). In the project a methodologyof proof load testing for existing bridges in new member states will be proposed. The paper shows the basisof the method as well as the application to an existing bridge located in Barcza (Poland). The bridge should beremoved in the next future and therefore the proposed methodology can be fully checked. 研究下多谢楼主分享！ 这个是什么的啊，没结束
