Behaviour and Design of Sustainable Stainless Steel Structures

不锈钢目前广泛应用于一系列行业，其主要优势是普通结构碳钢的耐腐蚀性和耐久性。在过去的十年里，对不锈钢的研究有了显著的发展，使其在结构用途上的应用越来越多。目前，尽管存在许多不锈钢的设计标准，但这些规定和检查通常是根据碳钢设计规则制定的，并与之相结合。不锈钢和碳钢具有明显不同的材料特性，因此规范反映这些特性以确保安全、高效和结构合理是很重要的。这项工作的重点将放在不锈钢框架的整体分析和梁柱设计的发展，以实现安全和高效的设计。持续强度法是一种基于变形的金属结构设计方法，它比现行标准提供了更高的设计效率，由帝国理工学院土木工程系设计，也将被考虑扩展和发展。总体而言，博士研究的目的将是制定增强的设计规则，以促进不锈钢作为可持续建筑材料的更广泛使用。

Stainless steel is currently widely used across a range of industries with its key advantage over ordinary structural carbon steel being its corrosion resistance and durability. Research into stainless steel has developed significantly over the last decade, enabling its increased use for structural purposes. Currently, although a number of design standards for stainless steel exist, the provisions and checks have generally been developed following, and in conjunction with, the carbon steel design rules. Stainless steel and carbon steel have distinctly different material characteristics and therefore it is important that the codes reflect these to ensure safe, efficient and structurally sound design. The focus of this work will be on the global analysis of stainless steel frames and the development of beam-column design to allow for safe and efficient design. The extension and development of the continuous strength method, which is a deformation based design approach for metallic structures that offers improved design efficiency over current standards, and was devised in the Civil Engineering Department at Imperial College, will also be considered. Overall, the aim of the doctoral research will be to develop enhanced design rules to promote the wider use of stainless steel as a sustainable construction material.
