Fire resistance of complex light gauge steel framed wall systems

该项目旨在研究高强度轻钢框架（LSF）墙体系统在暴露于火灾时的热学和结构行为，并开发一个通用模型来预测所有LSF墙体系统的耐火水平。石膏板衬里的LSF墙越来越多地被用作低成本的中低层建筑承重墙。这就要求新的墙体设计采用复杂的钢钉墙结构，但其防火性能尚不清楚。该项目将为拟议的国家防火设计手册和钢材设计规范提供经过验证的耐火数据和防火设计方法，使这些墙体能够更广泛、更安全地使用。这将使澳大利亚的钢铁行业、建筑业和社会受益。

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.
