Abstract
Flat slab is a commonly used and competitive structural system where columns directly support the floor slab without the need for beams. Openings in flat slabs can serve architectural purposes, such as accommodating stairways, elevators, and utility systems. However, it is important to note that adding an opening adjacent a column creates a critical location in the structure. This can disrupt the load path and create structural vulnerabilities. One common failure mode for flat slabs is punching shear, where the load is concentrated around the column, leading to brittle failures. To improve the resistance against punching shear, drop panels are often used. These panels increase the slab thickness around the column, specifically in the area with the highest shear stresses. This study analyzes eight different models of flat slabs, divided into two groups: one without drop panels and one with drop panels. the flat slab without drop panel and with drop panel is further divided into the without opening and with opening at different position from column face. the opening dimensions 2.0 x 2.0 m and is square in shape. All models are analyzed using the CSI-SAFE software based on the Indian Standard code for reinforced concrete structures.
