Abstract |
In this study, Full-scale hollow slab Mock-up with VPS(Void Plywood Slab System) was produced. Through Mock-up, the safety of the flat plate hollow slab against short-term sagging and long-term sagging is to be evaluated. The hollow rate of the mock-up specimen to which the hollow core slab was applied was designed to be 24%. When loading through concrete blocks, the most central part of the slab was deflection 8.88㎜ when loading. However, it shows a safe value compared to the reference value (ln/240=17.93㎜) for short-term deflection. As a result of 3 months of measurement of the mock-up experiment, the deflection at the center of the slab increased by 6.792㎜ from the initial deflection. In addition, it was found that the reference value by the load used suggested by KBC2016 was satisfied.
