In the flat plate system, replacing the concrete, where affects less performance of bending capacity of slab, with void enable to save the story height, to make longer span. Also using the deck plate under the void slab can develop the workability, and reduce the term of work. In this study, to evaluate the performance of the bending capacity of the two-way void slab, actual size of specimens were tested with parameters of the existence of void, the spacing of voids, and the depth of the slab. As a result, the standard specimen of T-V-300 presented similar bending capacity with the solid slab. Although the deck plate improving workability increases the ultimate stress 26%, the stress decreases very rapidly at the ultimate stress. It is considered that the structural performance of the deck plate is neglectable. |
