Abstract

This review presents fresh evidence on the last decade (2010–2021) of research related to numerical modeling techniques that have been employed to comprehend the lateral resistance and buckling behavior of cold-formed steel (CFS) sections when exposed to high temperatures. To attain the principal objective of this study, a systematic literature review (SLR) approach was adopted to address a review question on how numerical modeling has been utilized to investigate the buckling behavior and lateral resistance of CFS sections in elevated temperatures. In addition to the SLR approach, the Preferred Reporting Items for Systematic Reviews and Meta-Analyse (PRISMA) was employed to report all protocols involved in this review work. Based on the review, the impact of fire on the lateral resistance and buckling performance of CFS can be classified according to the type of software, fire curves, numerical models, and design standards. However, the lateral resistance of steel is not a specific attribute that can be measured or evaluated directly from numerical modeling methods. Instead, several structural components and variables can be analyzed as they contribute to the lateral resistance of steel.

本综述介绍了过去十年（2010-2021 年）与数值建模技术有关的研究的最新成果，这些技术被用于理解冷弯型钢 (CFS) 截面在高温下的侧向阻力和屈曲行为。为实现本研究的主要目标，我们采用了系统文献综述（SLR）方法来解决一个综述问题，即如何利用数值建模来研究 CFS 截面在高温下的屈曲行为和侧向阻力。除 SLR 方法外，还采用了系统综述和元分析首选报告项目 (PRISMA)，以报告本综述工作所涉及的所有协议。根据综述，火灾对 CFS 抗侧能力和屈曲性能的影响可按照软件类型、火灾曲线、数值模型和设计标准进行分类。然而，钢材的抗侧能力并不是一个可以直接通过数值建模方法测量或评估的特定属性。取而代之的是，可以对若干结构部件和变量进行分析，因为它们会对钢材的抗侧能力产生影响。
