Distribution of Compressive Stresses in Transversely Posttensioned Concrete Bridge Decks
Publication: Journal of Bridge Engineering
Volume 11, Issue 1
Abstract
A parametric study was carried out in order to understand the salient aspects affecting the distribution of compressive stresses in transversely posttensioned concrete bridge decks. Alternative finite element modeling techniques and alternative software were considered and the corresponding analytical results were compared with the experimental results from previous investigations. It was found that the distribution of compressive stresses is mainly affected by the support conditions of the girders and the axial stiffness of the diaphragms.
