Effects of Transverse Prestressing in Bridge Decks
Publication: Journal of Structural Engineering
Volume 114, Issue 4
Abstract
Transverse prestressing of bridge decks is an attractive concept with substantial benefits in both economy and improved durability. This paper summarizes a series of interrelated physical tests and computer analyses which were conducted to provide necessary information for the development of design criteria for transverse prestressing of bridge decks. It addresses such important design areas as the effective distribution of edge prestressing force across a bridge slab as affected by both diaphragm and girder restraints; the behavior of transversely prestressed decks under typical wheel loadings; and the effect of posttensioned strand spacing on the distribution of horizontal slab stresses near the deck edge. The principal attention is focused on slab and girder bridges. Experimental verification of the finite element analysis program developed for use in the research allowed substantial parameter studies to be carried out with reasonable confidence.
