Evaluating the Performance of Hollow Core Slabs (HCS)-Concrete and Simplifying Their Implementation

Abstract

The largest proportion of the material used in multistory buildings, and thus its carbon impact, is attributed to their slabs being the main contributor of weight. Because of their high strength and concrete self-weight reduction, composite beams with hollow-core slabs were created for their technical and economic benefits, making this system inexpensive and with a reduced environmental impact, thereby lowering carbon emissions. Geometrically, the hollow slab has a sequence of T and L form pieces on both sides. Hollow slabs are a newer roof feature with a little study undertaken in mechanical characteristics that prove its benefits and downsides in construction. It also has sufficient rigidity. In this work, numerous 19 hollow slabs and flat slabs are modeled using the finite element method, and the findings are compared in terms of hollow slab behavior and economic cost. It demonstrates that reducing the concrete beneath the hollow slab promotes cost-efficiency and the effective use of concrete and steel resources and various approaches for this form of the hollow slab are provided. Implementing a modern double-side beam slab is possible using the presented methods in this paper. It opens a door for creating structures with high stiffness and strength versus vertical and lateral load, along with low material volume.

Assessment of Composite Bars and FRP Panels for Seismic Bridge Decks

“…As part of our study, we have examined the utilization of high-module externally bonded longitudinal FRPs on slender reinforced concrete (RC) columns. Our findings indicate that incorporating longitudinal FRP laminates enhances the loadcarrying path of slender columns and optimizes their axial performance [23], [24]. This improvement is achieved by fortifying the stiffness of the columns through additional reinforcement provided by the longitudinal FRP laminates [25], [26].…”

Comprehensive Investigation of the Omega-Shaped Hybrid CFRP Sheet - Concrete Slab System: Experimental, Numerical and Analytical study

“…Over the last decades, extensive experiments have been carried out on the structural efficiency of one and two-span composite slabs with concrete and steel sheeting with or without embossing or mechanical connectors. In addition, researchers have performed a wide variety of finite element simulations of these composite slabs [5], [6]. Full scale tests of composite slabs were accurately modelled in the research by Veljkovic [7].…”
