Nonlinear Finite Element Analysis for Ultimate Flexural and Shear Capacity of Void Deck Slab

Concrete void RC slab has its own empty spaces inside on purpose. The nice aspects of this appearance of internal void are basically areduction of self-weight and possible mitigation of noise between floors especially for a residence building. In the past, it has been great research interests on shape and size of void and fixture for anti-floating during cast of fresh concrete. This was simply the main concern for construction. Nevertheless, this enhancement was achieved by introducing the steel deck plate at the bottom of void slab.Their flexural/shear capacity were needed to be proven by both experiment and analysis. The series of nonlinear finite element analysis were performed in terms of change of slab depth or a/d, presence of steel deck plate, area of longitudinal steel reinforcement in tension. Their failure patterns, load-deflection relations were extensively discussed and compared.
