Analysis of Bridge Deck Slabs. Stages I, II and III

摘要

This final report presents the results of a research project on the analysis of continuous skew bridge deck slabs of variable rigidity with or without edge beams. The solution is found by expressing the plate deflection in terms of a combined single and double summation series. The number of arbitrary constants is chosen such that they equal the number of equations expressing the boundary conditions and those used for minimizing the error function. The error function is minimized by imposing a set of orthogonality conditions similar to those used in the standard Galerkin Method. The method used, however, is different from the standard procedure in that the assumed expression for the deflected shape does not satisfy the boundary conditions term by term but each condition is satisfied by developing the boundary equation in a single Fourier sine series and setting each Fourier coefficient equal to zero. Three computer programs have been developed using Fortran IV. Program A serves to determine the deflections, moments and support shears due to uniform loading as well as the extreme values due to truck loading. Program B calculates the extreme values of deflection, moments and support shears due to lane and knife edge loading. Program C is for a single concentrated load and can be used to calculate the effects of a single span loaded uniformly. (Author)
