Shear Strength of Void Slab with Polystyrene Forms

Article Preview

Abstract:

Void slab systems with polystyrene form and precast concrete deck have been used to reduce the construction period and the self-weight of the slab. This paper presents experimental works on the shear of the void slabs. Four specimens were tested. The main parameters of experiments were the type of polystyrene forms and the thickness of slab. Shear performances of void slabs were evaluated on the basis of failure patterns, load-displacement curves, and ultimate shear strengths. Based on the test results, the unidirectional void slabs had the best shear resistance performance when they used PF2 type of polystyrene forms. For all specimens that failed due to shear, ultimate shear strength was 52% or higher than nominal shear strength by ACI318-08. This indicates that void slabs have a sufficient shear performance in the truss bar arrangement direction
