Abstract In this study, the serviceability performance of Waffle Shaped(WAS) and Double-Tee(DT) precast concrete slabs were evaluated and compared based on the vertical acceleration magnitude induced by walking and heel drop loads. Tests were conducted for practical building structures of which floor systems used WAS and DT slabs. Natural frequencies of the slabs were similar to those obtained by using analytical models. The measured acceleration level was evaluated by vertical floor acceleration criteria presented by ISO-2631, AIJ(1991, Japan) and a previous study regarding floor vibration limit. Test results showed that both WAS and DT slabs satisfied all the criteria and Peak acceleration level of WA slabs was lower than that of DT slabs.
