DESIGN OF OVERHANGING CANTILEVERED FALSE WORK

摘要

Construction of buildings with non-typical floors creates risky situations at which cantilevered slabs and beams are extended while the floor beneath has no cantilevered slabs on which the false work could rest. The design proposed in this paper is based on using cantilevered frames to support the formwork system with no need for extending the false work along the height of the building. The optimal dimension of the overhanging portion of the structure was derived. A closed form solution for the temporary structure was formulated. A parametric study was performed using the closed form solution to study the variations of the straining actions within the structural members while changing their dimensions. The study was extended in order to pick the most economic dimensions of the structure for each cantilevered span.
