【 摘 要 】

This paper proposed an innovative waffle slab, which had obvious distinction in configuration compared with traditional waffle slab and possessed the superiority on multi-storey residence building. In order to investigate the thermal behavior of this innovative waffle slab, the numerical simulation was carried out by ABAQUS software in this paper. The bottom of slab model was exposed to fire and the ISO-834 standard temperature curve was adopted. The temperature distribution was first analyzed and discussed, and the results showed the ribs behaved as the single side fire-exposed beam. The maximum temperature of slab top could reach up to 200°C after a fire-exposed of two hours. And a calculation formula was proposed by model data to predict the fire ablation depth.
