Analysis of a Tall Structure Considering Hollow Slab Using ETABS

Abstract

A significant amount of the construction budget and national capital is spent on the construction of concrete building structures as the number of residential, commercial, and institutional buildings rises. Precast Hollow Core Slabs (HCS) have, however, proven to be more desirable than RCC slabs in recent years due to the demand for economical and quick construction, and they have been suggested as a workable substitute for RCC slabs. 
The comparative analysis of a G+9 storey structure using three different slab types—flat slab, precast hollow slab, and post tensioned slab—is shown in this research. Using the analytical application ETABS, the modelling and analysis of all case studies are carried out, and the results were compared in terms of the parameters of storey displacement, storey shear, base shear, bending moment, axial force, and storey drift.
Precast slabs consisting of pre-stressed concrete with tubular spaces around their perimeter are used in multi-story homes as flooring because they are inexpensive, have strong acoustic and thermal insulation qualities, and can be made across long distances at a reasonable cost. A hollow core plate was employed to reduce core shear in the X and Y directions independent of the area because of the overall light weight of the construction. The displacement conserved in both directions increased in all places while the time reduced uniformly across all of them.
