Abstract
A redecking method for damaged reinforced concrete slab is proposed. The prefabricated steel deck of battledeck floor type, which consists of a deck plate, longitudinal ribs and small transverse ribs, is used and some cross beams are added to the existing bridge to support the deck. Static loading tests of large scale models were carried out and the structural details were developed. Fatigue tests of the models were also conducted to check the durability. Applying this method, a bridge was widened and reinforced. Two loading tests of the bridge were executed, i.e. during the construction and after the completion. This paper presents the outline of these tests and the reconstruction work.
