Abstract
Corroded beam specimens, sawn from reinforced concrete bridge which was constructed about 80 years ago in the coast of the Japan sea, is loaded until failure. The structural performance of beam specimens are subjected to the effectiveness of lap splice because each beam specimens contain several corroded lap splices. The reduction in load carrying capacity is comparable to the corrosion rate when lap splices work effectively. On the other hand, load carrying capacity is significantly reduced when lap splices are degraded due to severe corrosion. FE analysis are conducted to be compared with test results. FE analysis can estimate the load carrying capacity of beam specimen by considering average corrosion rate when lap splice works well. On the other hand, the effectiveness of each lap splices should be preliminary known if we want to simulate the structural performance of severely deteriorated beam specimen accurately.
