摘要

冷弯型钢(CFS)产品用途极为广泛,可用于多种用途。作者最近的实验测试表明,在由冷弯型钢梁和轻质混凝土组成的系统中调动复合作用是可行的,并能显著改善结构性能。然而,它们在高温下的行为还有待研究;因此,这是本研究的重点。本研究报告了 CFS-LWC 梁在环境温度和高温下的两次测试结果。然后介绍了使用火灾动力学模拟器 (FDS) 软件进行的数值建模研究,其中成功地复制了温度变化情况。

BUILT-UP COLD-FORMED STEEL-LIGHTWEIGHT CONCRETE (CFS-LWC) COMPOSITE BEAMS SUBJECTED TO ELEVATED TEMPERATURES

Cold-formed steel (CFS) products are extremely versatile and can be used in multiple applications. Recent experiments tests by the authors have shown that mobilising composite action within systems comprising cold-formed steel beams and lightweight concrete is feasible and can lead to substantial improvements in structural performance. However, their behaviour subjected to elevated temperatures has yet to be investigated; this is, therefore, the focus of the present study. The results of two tests on CFS-LWC beams at ambient and elevated temperatures are reported. A numerical modelling study using fire dynamics simulator (FDS) software is then described in which the temperature development was successfully replicated.
