Abstract

The Light Steel Frame (LSF) construction system is a method that utilizes light and galvanized steel structures composed of cold-formed profiles. These profiles come together to create both structural and non-structural frames, with various coatings. However, in fire situations, the metal structure can be affected, altering its mechanical properties and potentially leading to collapse. This study examined the behavior of a Steel Frame structural panel coated with gypsum boards during a fire, using numerical analyses with the ANSYS software. The results provided insights into the fire resistance of the structure.

火灾条件下冷弯型钢框架板的结构和热性能研究
轻钢结构(LSF)建筑系统是一种利用由冷弯型材组成的轻型镀锌钢结构的方法。这些型材通过各种涂层组合在一起,形成结构性和非结构性框架。然而,在火灾情况下,金属结构会受到影响,改变其机械性能,并可能导致倒塌。本研究使用 ANSYS 软件进行数值分析,研究了涂有石膏板的钢框架结构板在火灾中的行为。分析结果有助于深入了解结构的耐火性。
