Fire performance and design of light gauge steel frame wall systems exposed to realistic design fires

Overview

This thesis has investigated the fire performance and design of light gauge cold-formed steel frame walls under realistic fires which occur in modern buildings. It examined the appropriateness of using the standard fire curve to represent the modern building fires in full scale laboratory tests and developed suitable realistic design fire curves. Experimental and numerical studies of light gauge steel frame walls using realistic fires led to the verification of existing fire design rules based on Australian and International standards and the development of simplified fire design rules. This research has significantly improved the understanding of fire severity in modern buildings and developed valuable fire design tools for light gauge steel frame walls used in these buildings.
