Abstract:
In this study, a new concrete slab stiffened by concrete pedestals and steel cables is introduced. The slab system is studied by employing both analytical and numerical methods. The steel cables are connected to the edges of slab and the concrete pedestals mounted at the bottom face of slab act as the middle supports of cables. The tension force in the cable and its inclination results in upward forces acting at the bottom face of slab. With the aims of classical theory of thin plates and the superposition technique, the problem of a simply supported rectangular slab stiffened by cables is studied analytically. The obtained results are verified by a numerical modelling implemented in SAP2000 program. Utilizing the numerical model, effects of cable angle, height of pedestals, and layout of pedestals on the slab deformation are studied. The cost of the introduced system for a long span square slab is compared with other types of slab including flat plate, pan-joist floor, and waffle systems
