Abstract

This test program is to investigate the benefits of using headed bars to replace conventional stirrups and using steel fibers to reinforce in the disturbed regions in the dapped ended beam, This distribution of reinforcement was selected for aspects associated with the portion of beam section in bridge structures. The beams containing T-headed bars have a superior performance such as improved ductility, larger energy adsorption and enhanced post-peak load carrying capability. The capacity of DEB with steel fibers also show increase of ductility, shear strength, and crack.
