The purpose of this study was to evaluate the structural performance of Two-way Void Slab(TVS) through a comparison with the solid slab and to propose a structural design guide. For the structural performance tests, a total of 12 full scale specimens, i.e., 8 specimens for bending tests and 4 specimens for shear tests, were producted. From the results of structural performance tests, it can be seen that the bending strengths of all the bending specimens were larger than the ultimate bending strength on a basis of theory and the shear strengths of all the shear specimens were larger than 60 percents of the shear strength. According to the results of experiment, the initial flexure stiffness ratio was 0.98. Also, the maximum shear capacity ratio was 0.61～0.71. The proposed two-way void slabs, therefore, showed similar bending capacity compared with the solid slab and the shear strength reduction factor, 0.6, was suggested. |
