摘要： A prestressed composite beam structure from which the expansion joints, which were inevitably used in the conventional prestressed composite beam structure can be removed so that the structural and functional problems owing to the expansion joints can be solved and the span of beams can be lengthened, and construction materials can be considerably saved. The construction method in which the composite beams can be made into divided short beams in order to overcome the difficulties of transportation and handling in cases where the length of the prestressed composite beam is long. After the preflexion loads have been applied to the beam which was profiled in reverse to the sag curve of the continuous beam structure, concrete is cast and cured on the flange, and then the preflexion is removed. The problems of the negative moment on the connection between the beams is solved by lifting or lowering the support. For quick and easy assembling with the prestressed slab, the composite beam has shear key grooves and a reinforcing beam.
