Review on Prepare and Test Hollow Slab with Economical Comparison

Abstract

Slab systems happen to be the most material-demanding parts in a reinforced concrete building and their proper functioning is important for the structural safety, serviceability, and cost, and energy efficiency. Though widely considered and the solid conventional reinforced concrete slabs have consumed big amounts of concrete and steel, heavier dead loads are their outcome and there is an increased load on the beams, columns, and foundations as well. Over the last few decades, hollow and voided slab systems, such as hollow-core slabs, bubble deck slabs, and voided flat slabs, have been viewed as sustainable solutions because they need less material and their structural efficiency is better. This review paper provides a thorough synthesis of recent research on hollow slab technologies focussing on structural behaviour, flexural and punching shear performance, deflection features, construction methods, strengthening techniques, and economic viability. The literature's experimental, numerical, and analytical studies are rigorously analyzed to discern the advantages, limitations, and performance trends of the different hollow slab systems. Furthermore, the paper indicates the present research gaps concerning code provisions, long-term behavior, and system-level cost evaluation. By reviewing the literature, the authors want to provide support for engineers and researchers in their endeavors to choose and optimize hollow slab systems for constructing safe, cost-effective, and energy-efficient buildings.
