This project aims to investigate the thermal and structural behaviour of high-strength Light gauge Steel Framed (LSF) wall systems when exposed to fire, and develop a generic model for predicting fire resistance levels of all LSF wall systems. Plasterboard-lined LSF walls are increasingly used as cost-effective load-bearing walls in low and mid-rise buildings worldwide. This has required new wall designs with complex steel stud wall configurations, but their fire resistance is not understood. This project will provide validated fire resistance data and fire design methods for a proposed national Fire Design Handbook and steel design codes, enabling more widespread, safer use of these walls. This will benefit the Australian steel industry, the construction industry and the community.

该项目旨在研究高强度轻钢框架（LSF）墙系统在火灾下的热性能和结构性能，并开发一个通用模型来预测所有LSF墙系统的耐火水平。石膏板内衬LSF墙越来越多地被用作低层和中层建筑物中具有成本效益的承重墙。这就需要新的墙设计与复杂的钢柱墙配置，但他们的耐火性是不了解。该项目将为拟议的国家防火设计手册和钢结构设计规范提供经过验证的耐火数据和防火设计方法，从而使这些墙壁能够更广泛，更安全地使用。这将使澳大利亚钢铁业、建筑业和社区受益。
