Redesign of Hollow Core Slab by Using Various Core Shape

Abstract

Hollow core slabs represent a widely used structural element in the construction industry due to their exceptional structural efficiency, versatility, and cost-effectiveness. These precast concrete elements feature longitudinal voids, or cores, which not only reduce the overall weight of the slab but also provide an efficient means of incorporating mechanical and electrical services within the floor system. This abstract provides a comprehensive overview of hollow core slabs, focusing on their design, manufacturing process, structural behaviour, and applications.

The design of hollow core slabs involves considerations such as load-bearing capacity, span length, deflection limits, and fire resistance. Various design standards and guidelines govern the structural design process, ensuring compliance with safety and performance requirements. Manufacturing techniques for hollow core slabs typically involve extrusion or slip forming of precast concrete elements, followed by curing and finishing processes. These techniques result in consistent quality and dimensional accuracy, contributing to the reliability of hollow core slab systems.
