Numerical Investigation on Fire Performance of LSF and Steel Modular Floor Panels

The steel Modular Building Systems (MBSs) that have been influenced by the Light-gauge Steel Frame (LSF) techniques become a prominent culture in industry. However, detrimental behaviour of structural components at high temperatures has elevated risk fatal accidents event fire. Although several research investigations addressed fire performance modular wall systems, floor systems not adequately state art. Hence, to promote safety and optimum design construction industry addressing aforementioned gap, this study investigated 48 conventional LSF MBS floors for their insulation Fire Resistance Levels using Finite Element Modelling (FEM) Heat Transfer Analyses (HTA) techniques. Initially, full-scale experimental tests were modelled FEM methods, validity was verified prior analyses parametric systems. Furthermore, channel section joists studied, hence correlation established determine critical temperature failure with respect applied Load Ratio (LR). An additional 12.5 mm thick plasterboard sheathing on single sheathed resulted 30 min improvement FRLs. In addition, demonstrated enhanced (FRLs) against corresponding designs due double skin build-up. incorporation rockwool increase volume implied increased performances. material more effective. fire-rated are expected be practised achieve required resistances usage.
