ANALYSIS OF CONTINUOUS HIGHWAY BOX BRIDGES WITH INTERMEDIATE STIFFENING

The finite strip method has proved to be accurate and efficient for the analysis of single-span slab and box-type highway bridges, by incorporating a general flexibility procedure. The strip method is herein extended to encompass multispan structures with intermediate stiffening members. With the extended approach, intermediate supports may be replaced by bearings, hinges, columns, bents or they may be built-in; stiffening members may take the form of a truss, a frame or a solid diaphragm. In this paper, the development of the general flexibility approach is presented with a recapitulation on the finite strip method for simply-supported bridges. Comparisons of results indicate that in addition to improved accuracy, considerable savings in computing costs can be achieved by using the extended finite strip procedure over a finite element program specially developed for box bridge analysis. /TRRL/
