Abstract

The architectural design 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 steel cantilevered trusses to support the formwork system with no need for extending the false-work along the height of the building. A closed form solution for the truss was formulated and validated using a commercial software. A parametric study was performed using the closed form solution to study the variations of the straining actions within the truss member with the truss dimensions. The study was extended in order to pick the most economic dimensions of the truss for each cantilevered truss span.
