This project plans to investigate the use in building frames of composite steel-concrete members that use high-strength steel (HSS) instead of mild steel (MS). HSS is finding increased use in construction, and HSS has a much greater strength-to-weight ratio than MS, leading to lighter composite structures, less material usage and smaller foundations. Overall, this reduces the cost and carbon footprint of steel-framed buildings. The investigation is planned to involve physical testing, numerical studies, developing structural models and crafting design guidance for T-beams, columns and joints. The major intended outcome of the project is design guidance that will support the expanded use of HSS.

本项目计划研究使用高强度钢（HSS）代替低碳钢（MS）的钢-混凝土组合构件在建筑框架中的应用。HSS在建筑中的使用越来越多，并且HSS的强度重量比MS大得多，从而导致更轻的复合结构，更少的材料使用和更小的基础。总体而言，这降低了钢结构建筑的成本和碳足迹。调查计划涉及物理测试，数值研究，开发结构模型和工艺设计指导T梁，柱和接头。该项目的主要预期成果是提供设计指导，以支持HSS的扩大使用。
