EXPERIMENTAL STUDY OF PRESTRESSED COMPOSITE BEAMS

The experimental study is reported of the behavior of prestressed, composite steel-concrete beams. Two beams were tested: one subject to positive bending moment and the other to negative bending moment. The load was plotted against the deflection, and the strains in the concrete, steel beam, and prestressing bars. The results of the study showed that adding prestressed bars to composite beams significantly increased the yield load and the ultimate load. The farther the bars are located from the neutral axis, the greater is the increase in strength. An adequate number of guides are needed to ensure that the bars follow the beam curvature. These and other study findings are discussed.
