Concrete Bridge Design

TL;DR: In this paper, the service load level behavior was studied under static, cyclic and impact loads with successive removal of diaphragms, and the only significant role of interior diophragms was to distribute the load more evenly.

TL;DR: In this paper, a modified approach based on the orthotropic plate theory for computing the natural frequencies of bridge slabs is presented through a set of empirical relationships between the plate parameters, and the results from the present investigation are compared with those obtained by other methods; good agreements are obtained.

TL;DR: In this article, the boundary element method is employed to analyze the top slabs of rectangular or skewed composite slab-on-girder and box-girders bridges, while the finite strip method is used to analyse the girders.

TL;DR: In this article, a simplified analysis method considering the effect of girder deflection is developed, based on an analytical solution obtained with the elastic plate theory, for the maximum negative bending moment in a bridge deck.
