Flexural Cracking Behavior of Partially Prestressed Pretensioned and Post-Tensioned Beams--State of the Art

Abstract

Simple mathematical expressions have been developed as a result of the work at Rutgers University corroborated by comparative analysis with other authors. The proposed expressions for evaluating crack widths in partially prestressed beams at working load and overload levels have been developed in terms of the controlling parameters, namely, the variation in the steel reinforcement and percentage of the prestressing tendons and the non-prestressed reinforcement.
