This project aims to improve the coupled service and strength load behaviour of high strength composite columns used in building and bridge infrastructure. Taller and longer buildings and bridges need efficient and safe material. Australian Standards for concrete and steel now allow higher strength materials of 100 and 690 MPa. This project will consider coupled service and strength load issues incorporating time-dependent effects and ductility, and extend the range of concrete and steel strengths to 150 and 960 MPa for world-class heavy infrastructure. This project is expected to improve the safety and economy of tall buildings, bridges and large infrastructure.

该项目旨在改善建筑和桥梁基础设施中使用的高强度复合柱的耦合服务和强度荷载行为。更高更长的建筑物和桥梁需要高效、安全的材料。澳大利亚混凝土和钢材标准现在允许采用 100 和 690 MPa 的更高强度材料。该项目将考虑结合时间依赖性效应和延展性的耦合服务和强度载荷问题，并将世界级重型基础设施的混凝土和钢材强度范围扩大到 150 和 960 MPa。该项目预计将提高高层建筑、桥梁和大型基础设施的安全性和经济性。
