| Several utility requirements necessitate the installation of holes in certain concrete structures. Due to the reduction in concrete area in the cross-sectional dimension, the structural component may exhibit complex behavior. Thus, the study investigates the behaviour of plain cement concrete (PCC) and reinforced cement concrete (RCC) one-way slabs with holes and its effect. Eight numbers of PCC and RCC slabs with and without holes were made in various (i.e., circular, square, and hexagonal) shapes by maintaining the same area of opening. Load versus mid span deflection response curve, load carrying capacity, failure modes and energy absorption capacity were investigated and considered as indicators of structural slabs performance. It has been observed that PCC and RCC slabs with circular holes exhibited greater load carrying capacity than slab models prepared with hexagonal and square holes. The slabs with square hole experiencing more cracks compare to circular and hexagonal holes present in slabs because of sharp edge corners. Slabs with circular hole exhibited greater energy absorption capacity than the slabs with hexagonal and square holes. Finally, it can be stated that the geometric configuration of the hole substantially impacts the performance of slabs, and opting for circular holes is the most favourable choice. | ||
