Abstract
Flat slab though have pleasant aesthetes is critical in punching shear. The flat slab may have openings for various architectural concerns such as stairways or elevators, the transition of gas, electricity, water and air-conditioning systems, etc. This opening may be anywhere in the slab, but the most favourable location is the one next to the column since continuity of the carpet area is undisturbed. But, providing an opening adjacent to column implies providing the opening at the most critical location. Due to an opening adjacent to the column, the punching shear capacity is most affected, which results in the failure of the structure. One shall also notice the vulnerability of such type of failures since this type is a failure, brittle in nature; there are no signs of failure as a warning. The failure is sudden and may cause the collapse of the whole structure. To avoid such type of failure, one shall analyse the structure at the time of construction itself and take safety measure at the time of construction itself. The objective of this study is twofold—firstly, the size of the opening and secondly, the location of the opening in the flat slab. In this paper, seven different models/specimens have studied in which six models have an opening of size 1.2 × 1.2 m, 2 × 2 m or 3 × 3 m adjacent to column face. Openings are placed parallel to the face of the column or diagonal to the face of the column. And first model is the control specimen without opening. All these models are analysed by finite element analysis-based software CSI SAFE 2016.
