【 摘 要 】

An innovative prefabricated steel-truss waffle slab system has been proposed in this paper, which has obvious distinction in configuration compared with traditional waffle slab and possesses the superiority on multi-storey residence building. In order to investigate the flexural behavior of this innovative waffle slab, the numerical simulation was carried out by ABAQUS software in this paper. The slab model was simply supported at four corner points and subjected to four-point vertical load at the joint of ribs. The results obtained from the numerical simulation had been discussed and analyzed in the context of ultimate flexural load, failure mode, load-vertical deflection relationship and strains on rebar and concrete. The slab failure was governed by the rebar strength. Typical shearing stress developed at one-third span of end beams. It was verified that the ribs was main bearing component. The numerical results showed that the slab behaved as a two-way solid slab.
