Abstract |
In this study, the flexural capacity of one-way void slabs was evaluated by inserting a deck plate with removable steel sheets and a “bean” type void sphere that effectively applies a void ratio. Two specimens were fabricated and tested to verify the flexural capacity of one-way void slab of removable deck plate. Experimental results show that the bending strength of general deck and void deck are 6.6 % and 15.8 % higher than those of KCI2012, respectively, and the typical flexural failure behavior of the cracks propagation at both ends after initial cracking occurred at the center of the slab. In addition, the section performance was verified through the moment of inertia. As a result, the void deck with a void ratio of 32.8 % satisfies the flexural capacity of the one-way void slabs of the KCI2012 structural design standard and replaces the ordinary reinforced concrete slab to reduce the slab weight and to improve the workability and Eco-friendliness.
