Abstract:
This study investigates the performance of precast thin panel as permanent formwork for precast
composite slab. The two-way inverted ribs in the thin panel are placed to enhance its flexural
stiffness, as well as providing link between the precast layers. Flexural behaviors of two precast
panels are investigated under two line load and distributed load. Test results indicate that the thin
panel with suitable ribs layout and support distance can be used as permanent formwork. Typical
load from construction worker and in situ elements could be sustained by the panel.
