Sustainable Steel-Timber Hybrid Structures in Fire

业主和设计师对钢木混合建筑的需求越来越大，他们希望为多层建筑寻求更环保的解决方案。这些混合系统基于钢梁和柱的框架，在结构上与交叉层压木（CLT）地板相结合，正被用作多层办公楼钢结构建筑与混凝土板的竞争力和创新性建筑替代方案。这种新的高层建筑方法通过减少约50%的隐含碳影响，比成熟和广泛使用的钢-混凝土建筑提供了显着的环境效益。然而，这类建筑物的结构防火性能令人关注。拟议的工作旨在提高对CLT板钢框架建筑防火性能的理解，并开发钢木混合结构的结构防火工程分析能力。

There is a growing demand for steel-timber hybrid construction from property owners and designers seeking more environmentally sensitive solutions for multi storey buildings. These hybrid systems based on a frame of steel beams and columns, combined structurally with Cross-Laminated Timber (CLT) floors, are being used as a competitive and innovative construction alternative to steel buildings with concrete slabs for multi-storey office buildings. This new approach to high rise construction offers significant environmental benefits over the well-established and widely used steel-concrete construction by reducing the embodied carbon impacts by approximately 50%. However, there are concerns over the structural fire performance of such buildings. The proposed work aims to improve the understanding of the fire performance of steel framed buildings with CLT slabs and develop structural fire engineering analysis capability for steel and timber hybrid construction.
