Abstract
56 The purpose of this investigation was to study the feasibility of using a prestressed double tee concrete system in bridge structures with spans up to 80ft (24.4 m). The experimental investigation consisted of two parts: (1) study the behavior of a simply supported half scale bridge model with three double tees joined together by simple longitudinal V joints and transversely post-tensioned; (2) study the effect of prestressed steel profiles and shielded strands on the ductility of double tees.
