Sometimes there is in need to make openings in the slabs, and this greatly effects on the strength of the structural element. Therefore, this research studies the behaviour of one-way reinforcement concrete cantilever slabs and the extent of their effect and resistance. The number of openings, their location and sizes are the main parameters that have been studied. A comparison was made between four slabs with openings and a fifth reference model (solid slab). After conducting laboratory tests, differences were found in their behaviour and resistance. The decrease in the ultimate load reached 31.5%, while the deflection rate was a decrease between 3.2% and 62.7%. It was also found that the location and number of openings affected the behaviour of the slab.
Key words: Reinforced concrete / one-way slab / cantilever / opening, circle
