Abstract

The scope of this research is flat reinforced concrete slabs with openings near the middle column and without special reinforcement for accepting the shear forces caused by punching shear. Three reinforced concrete slabs supported on the rectangular column were analyzed. They differed only from the position of the opening in relation to the column. The opening for each slab had the same dimensions and shape, square with sides of 100 mm. The design values of the punching shear for the slabs with openings were obtained according to EC 2. Obtained values were compared with the design punching shear of the same slab without an opening, based on that, the influence of this parameter on the behavior of reinforced concrete slabs was determined.
