Abstract

This research investigates the flexural behaviour of fibre-reinforced lightweight hollow core slabs (FR-LWHCS) using numerical simulations. A three-dimensional finite element (FE) model is developed to replicate the response of the HCS in a four-point bending test. The HCS consists of lightweight aggregate and contains 0.6% of synthetic fibres. The nonlinear FE analysis is conducted using ABAQUS software and validated against previously published experimental results. The numerical model accurately predicts load-deflection behaviour demonstrating good agreement with experimental findings. Additionally, the FE analysis provides insights into crack patterns and failure modes of HCS. Detailed parametric studies considering the effects of changing the reinforcement, the HCS’s depth, and the shear span to depth ratio, size of core, and shape of core have also been performed.
