In this research paper, the focus is on studying the Dangerous zone of failure in concrete voided slabs. Voided slabs depict dangerous zones as conventional slabs. Voided slab, being the innovative method of building slabs that replaces failed concrete in the middle of the slab with a hollow sphere—known as Bubble Deck—has numerous advantages. These include lower material, load, cost, and span length. Furthermore, this article examined the effect of cavities created by using plastic balls on the punching action of self-compacted concrete since a slab's most crucial characteristic is its capacity to punch shear. The impact of utilizing different steel fiber percentages (0.8 percent, 1 percent) in the punching shear zone on the maximum punching shear load and deflection was also included. The same was validated using ABAQUS and was found that the results were in limit. After Validation, it was evaluated that the most dangerous form of failure whether in the conventional slab, or voided slab is punching shear failure and the most dangerous failure zone is punching shear failure zone. The values of failure were in the limit as stated in IS code 456:2000 in clause no 23.2.
