Flexural Strength Evaluation of One-way Void Deck Plate Slab with Polystyrene Foam

摘要

Use of hollow material in deck plate can reduce slab weight and improve the performance of fixing and installing hollow material. In this study, one-directional slabs were experimented with presence or absence of hollow material and deck plate depth etc as variable to evaluate the bending performance of deck plate that includes rectangular cross-section polystyrene hollow material. As a result of the experiment, when compared with the deck plate without hollow material, deck plate with hollow material was found to have similar bending yield strength and deformation performance. In addition, hollow material deck plate was evaluated to have greater strength performance than bending strength provided in ACI318-08 standard.
