Abstract
The structural behaviour of Precast Lightweight Foamed Concrete Panel (PLFP) under flexural load is investigated by using ABAQUS 6.13. The PLFP is made up of two Whyte’s with a polystyrene insulator placed in between them using a double shear truss connector of diameter 6mm placed at an angle 45°. The panel is reinforced with both vertical and horizontal steel reinforcement of 9 mm diameter. Four panels with varying dimensions are simulated to investigate their Ultimate Strength and Load-deflection profile. The results show that the length to thickness ratio of the panel is the major contributing factor to the ultimate strength of the PLFP. From the load deflection curve, the panel with the least deflection has the highest thickness which also results in a high ultimate strength recorded at 34.43 KN.
Highlights
A concrete slab is an element member of a modern structural building
The ultimate strength achieved by the Precast Lightweight Foamed Concrete Panel (PLFP) panels depended on various factors and not just the materials that are used for the analysis of various panels
The purpose of this research was to study the numerical simulation for the structural behaviour of Precast Lightweight Foam Concrete Sandwich Panel slab under flexural loading
Summary
A concrete slab is an element member of a modern structural building. The horizontal slab is mostly used to construct the floors or ceiling while the thinner and vertical slabs are used for exterior paving or walls. In many domestic and industrial buildings, a thick concrete slab supported on foundations or directly on the subsoil is used to construct the ground floor of a building. These can either be “ground-bearing” or “suspended” slabs. In high rise buildings and skyscrapers, thinner pre-cast concrete slabs are slung between the steel frames to form.

Structural lightweight aggregate has been successfully used for well over two millennia; it has had widespread use for the past ninety years
