A Critical Analysis of the Structural Performance of Flat Slab without Drop-Thin Plate System

Abstract

A thin plate, also known as a flat slab, is a reinforced concrete slab that typically lacks beams and girders, instead transferring loads directly to supporting concrete columns. These structures are widely used in industrial, commercial, and institutional settings. However, they are susceptible to shear failure, particularly in the case of flat slabs with no slab drop. The major drawback of this type of slab is punching shear failure, which can occur due to the slab's low thickness and inability to support heavy loads. Despite these limitations, flat slab without drop has gained popularity in recent years due to its many advantages. This review paper provides an overview of this structural system, including its design considerations, benefits, and applications. Additionally, the paper highlights past and ongoing research in the field and discusses the potential for future developments in this technology.
