BEHAVIOR OF STAGE-CAST INVERTED T-BEAMS WITH THE PRECAST FLANGE IN TENSION

The test program was intended to demonstrate the flexural behavior of stage-cast inverted T-beams constructed with a web cast in place against a preloaded flange. Four reinforced concrete T-beams were subjected to loads that caused compression in the web and tension in the flanges. Two of the specimens were stage-cast, while the other two, called control specimens, were monolithically cast and had the same size and reinforcement as the stage-cast beams. The behavior of stage-cast specimens was compared with that of similar control specimens to observe differences of ultimate strength, ductiility, stiffness under live loads, and the extent and size of cracks. /Author/
