Proof Load Testing of Highway Bridges

Load testing of bridges is a practice that is as old as their construction. In the past, load testing gave the traveling public a feeling that a newly opened bridge is safe. Nowadays, the bridge stock in many countries is aging, and load testing is used for the assessment of existing bridges. This paper aims at giving an overview of the current state-of-the-art with regard to load testing of concrete bridges. The work is based on an extensive literature review, dealing with diagnostic and proof load testing, and looking at the current areas of research. Additional available information about load testing of steel, timber, and masonry bridges, buildings, and collapse testing is briefly cited. For the implementation of load testing to the aging bridge stock on a large scale, efficiency in procedures is required. The areas requiring future research are identified, based on the available body of knowledge.

“…Several countries, such as Italy (Veneziano, Galeota, & Giammatteo, 1984), Switzerland (Bruehwiler, Vogel, Lang, & Luechinger, 2012) and France (Cochet et al, 2004b) require a diagnostic load test upon opening of a bridge. Proof load tests (Cai & Shahawy, 2003;Casas & Gómez, 2013;Moses et al, 1994;Saraf, Sokolik, & Nowak, 1996) use a higher load and proof a certain capacity of a bridge. Ideally, this capacity can be linked to a probability of failure of the bridge, so that the result of the test and analysis is an estimate of the safety.…”

“…In a proof load test (Grigoriu and Hall, 1984;Juntunen and Isola, 1995;Saraf et al, 1996;Ransom and Heywood, 1997;Faber et al, 2000;Cai and Shahawy, 2003;Anay et al, 2016), a load that corresponds to the factored live load is applied to the bridge structure, to directly demonstrate that a bridge fulfills the code requirements. The maximum load that needs to be applied to demonstrate that the bridge fulfills the code requirements is called the target proof load.…”
