Fibre Reinforced Polymer (FRP)-Confined Concrete-Encased Steel Composite Columns

澳大利亚及其他地区的基础设施长期以来因钢筋/截面腐蚀而恶化。该项目将通过研究一种新形式的混合柱来解决这个问题，即纤维增强聚合物约束混凝土包裹钢复合柱。结合纤维增强聚合物约束混凝土和钢截面的想法不仅使柱成为钢/混凝土柱的耐用和延展性替代品，而且使它们成为改造或加强老化钢柱的有效方法。本项目将研究纤维增强聚合物约束混凝土包覆钢复合柱的结构性能，并开发设计方法，为其广泛的实际应用铺平道路。

The infrastructure in Australia and beyond has long suffered from deterioration due to corrosion of steel reinforcement/sections. This project will address this problem by investigating a new form of hybrid columns, namely fibre reinforced polymer confined concrete-encased steel composite columns. The idea of combining a fibre reinforced polymer-confined concrete and a steel section not only makes the column a durable and ductile alternative to steel/concrete columns, but also makes them an efficient method for retrofitting or strengthening deteriorated steel columns. This project will study the structural behaviour of fibre reinforced polymer confined concrete-encased steel composite columns, and develop design methods to pave the way towards their wide practical applications.
