Abstract

The authors conducted on-site load test and 3D Finite Element Analyses (3D-FEA) of an existing prestressed post-tensioned concrete bridge with four post-tensioned T-girders, whose span length was 36 m, constructed in 1960 so as to clarify structural behaviour and its capacity of the bridge superstructure. It was found that the 3D-FEA combined with the linear surface spring elements which represents restraint of adjacent members can well simulate the actual structural behavior, the capacity and failure mode. Besides it is also discussed about the reason why capacity of a girder in superstructure becomes greater than a single girder with same cross-sectional properties.
