Model and Prototype Tests of a Curved Flyover, and Comparison with Computer Analysis

Field loading tests were carried out on a curved prestressed concrete flyover with a multibox section. The bridge deck was analysed using the ICL program for plane frames and grids. A 1/12 scale prestressed concrete model of the structure was also tested. Comparative study of the results from the three sources indicated that the elastic behaviour of the structure could be predicted by computer analysis or model testing with an accuracy acceptable for design purposes. Destructive test of the model also provided an estimate of the cracking load and the ultimate load of the prototype. H.W. Chung, P.K.K. Lee and D. Ho
