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 railway

systems of the European Union. Many of these bridges are very old bridges without documentation. A possible

way 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 level

that the bridge should resist during the proof test to guarantee a predetermined service load with a required and

appropriate 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 Project

ARCHES (Assessment and Rehabilitation of Central European Highway Structures). In the project a methodology

of proof load testing for existing bridges in new member states will be proposed. The paper shows the basis

of the method as well as the application to an existing bridge located in Barcza (Poland). The bridge should be

removed in the next future and therefore the proposed methodology can be fully checked.
