Performance Of Hybrid Green-Tech Lightweight Prism Composite Floor Panel
Abstract
Hybrid Green-tech Lightweight Prism Composite (HGLC) is a lightweight panel floor structure compared to conventional concrete slab because it has a thin cross-section which can reduce the load transferred to the structure of beams, columns and even the foundation of the building. Flexural strength studies on lightweight composite floor structures previously focused on strength test on a composite prism that changed the cross section of the profiled steel sheeting from a trapezium to a rectangle cross section. The objective of this study is to identify the performance of flexural strength composite prism by focusing on various parameter including cross-section, the use of dry boards and concrete infill. Apart from that, a comparison of the flexural strength value will be made on the difference cross section between the trapezium and rectangle composite prism compared to the control sample. Data analysis results found the flexural strength increase in rectangular composite prisms without dry board concrete infill (P6 Sample), which is 69% compared to trapezoidal composite prisms (P3 Sample) of only 37%. The bending moment for the P6 sample also increased by 74% compared to the P3 sample which was only 34%. Overall, the objective of this study was achieved when it was possible to identify a significant increase driven by the change in cross-section from the original shape of a trapezoid to a rectangle where there was a 27% increase in the moment of inertia. Therefore, this study has a positive impact, where the proposed rectangular cross-section profiled steel panel can be made into a high- performance lightweight composite panel structure for domestic buildings to support the use of the Industrialized Building System (IBS) in the future.
