Abstract

High performance steels, such as stainless steels, have many desirable characteristics that warrant their use in various sectors, including infrastructure and energy applications. This paper is concerned with two of such applications: (i) the use of stainless steel for large‐scale liquid hydrogen storage tanks, which is a requirement for the future hydrogen energy network, and (ii) the use of stainless steel in steel‐framed buildings to enhance their robustness under extreme loading conditions. The paper begins with a discussion of the technical challenges associated with the material behaviour of stainless steel storage tanks under extreme temperature and pressure conditions. It presents and discusses the results of a pilot experimental programme that investigates the mechanical behaviour of stainless steel 304 L material under cryogenic 20 k hydrogen environment. Next, to demonstrate the benefits of the strategic use of stainless steel in the key connection parts of steel‐framed structures, the paper presents the setup for a new test programme that investigates the behaviour of stainless steel beam‐to‐column connections, using A4‐70 bolts and EN1.4301 plates, under a column removal scenario. The numerical modelling prediction results of the specimens are presented, and comparisons with carbon steel counterparts are made and discussed.
应用于基础设施和能源领域的高性能金属材料
高性能钢,如不锈钢,具有许多理想的特性,保证了它们在各个领域的应用,包括基础设施和能源应用。本文关注其中两种应用:(i)大型液氢储罐使用不锈钢,这是未来氢能源网络的要求;(ii)钢框架建筑使用不锈钢,以增强其在极端负载条件下的坚固性。本文首先讨论了不锈钢储罐在极端温度和压力条件下的材料性能所面临的技术挑战。介绍并讨论了在低温20k氢环境下研究不锈钢304 L材料力学行为的试点实验方案的结果。接下来,为了证明在钢框架结构的关键连接部分战略性使用不锈钢的好处,本文提出了一个新的测试程序的设置,该程序使用A4‐70螺栓和EN1.4301板,在移柱场景下调查不锈钢梁柱连接的行为。给出了试件的数值模拟预测结果,并与碳钢试件进行了比较和讨论。

期刊介绍: Steel Construction publishes peerreviewed papers covering the entire field of steel construction research. In the interests of "construction without depletion", it skilfully combines steel with other forms of construction employing concrete, glass, cables and membranes to form integrated steelwork systems. Since 2010 Steel Construction is the official journal for ECCS- European Convention for Constructional Steelwork members. You will find more information about membership on the ECCS homepage. Topics include: -Design and construction of structures -Methods of analysis and calculation -Experimental and theoretical research projects and results -Composite construction -Steel buildings and bridges -Cable and membrane structures -Structural glazing -Masts and towers -Vessels, cranes and hydraulic engineering structures -Fire protection -Lightweight structures
