Abstract |
An ultra-high strength prestressed prismatic beam of 100 MPa in compressive strength was developed by increasing the watertightnessof concrete by utilizing centrifugal molding processes without adding expensive admixtures such as silica fume. The ultra-high strength centrifugalshaped square beam installed on the wall is composited with the upper slab concrete and then subjected to a service load. Horizontal shear stress isgenerated by bending between the centrifugal molding beam and the floor plate, which causes the beam and floor plate to perform composite behaviorthrough shear connections such as studs and rebars. In this study, a flexural load test was performed on a mock-up specimen that was synthesized byfabricating an RC slab on top of a 100 MPa-class centrifugal shaped beam produced at the factory. proven reliability.
