Experimental Verification of Precast Dapped-End Beams

Abstract

This article deals with the issues of designing the detail of the dapped-end beam, the design of which in practice usually employs the design method based on the strut-and-tie method. The most usual method for its reinforcing is described herein, including the selected suggestions that are mentioned in the literature. The article also presents the experiment carried out to verify the design method. A study shows the influence of the used amount of vertical and inclined hanger reinforcement on the bearing capacity and behaviour of the detail under load. The results show fairly good correspondence between the bearing capacity as determined by calculation and by the experiment. They also point out to the adequacy of using the inclined hanger reinforcement in relation to formation, development and final width of the cracks.
