Abstract

In this paper, three-dimensional finite element analysis of composite steel-concrete bridges is performed to simulate the
actual bridge behavior. The accuracy of the model is verified against the results acquired from a field test. Thai trucks are loaded
at possible locations of the bridge in order to obtain the maximum stresses on the bridge. The influences of concrete barriers,
the displacement of bridge piers, and the Young’s modulus of concrete are then discussed, to reveal the actual behavior of the
steel-concrete composite bridge. The reactions at the bearings on the bridge piers are also evaluated and discussed in this
conjunction. Good agreement is obtained between the models and loading tests to show that the finite element model can
aid engineers in design practices.
