Abstract
The pre-stressing method using high tensile strength steel plate can reduce both dead-load and live-load stress, by pre-stressing and by giving additional stiffness. In addition, the anchor detail of reinforcing steel plate to the reinforced beam can be much simpler than that of Outer Cable Method, because the common high-tension bolt joint can be used for the anchor structure. This method had been already confirmed to be so effective as predicted by the theory, through application work in existing bridges. In this study, as an application of this method to new bridges, we try to extend the span of H-beam bridge and reduce either the depth or the number of main girder by applying the Steel Plate Pre-stressing Method.
