STATIC AND FATIGUE TESTS OF COMPOSITE T-BEAMS CONTAINING PRESTRESSED CONCRETE TENSION ELEMENTS

This paper describes the static and fatigue behavior of composite T-beams using a combination of prestressed concrete tension elements and reinforcing bars as the tension reinforcement. Static tests indicated similar behavior of two continuous beams, one being designed with moment redistribution at ultimate load and the other without moment redistribution. Repeated load tests were performed on six composite beams. Test results indicated that by augmenting multiple tension elements with steel reinforcing bars, the endurance limit of the composite beams was increased by nearly 43 percent. It was also shown that, under repeated load tests, the maximum crack width of the beam exclusively reinforced with tension elements was approximately one-half of that of the similar beam reinforced with conventional bars only.
