This paper presents results of large-scale experiments with varying levels of fire severity on lateral force-resisting systems commonly used in cold-formed steel framed buildings. Gypsum-sheet steel composite panel sheathed walls, oriented strand board sheathed walls, and steel strap-braced walls are examined. Postflashover fire conditions of two different intensities as well as 1 hour of fire exposure similar to that in a standard furnace qualification test are studied. Additionally, a full-scale furnished kitchen fire experiment is conducted for comparison. The results highlight differences in the thermal response and subsequent performance of the walls as well as differing sensitives of the walls to pre-damage, eg, that might occur during an earthquake. The results are part of a larger effort to provide fragilities for these wall systems in response to realistic fires for performance-based design.

不同火灾场景下冷弯型钢框架剪力墙的耐火性能


本文介绍了冷弯型钢框架建筑中常用的抗侧力系统的不同火灾严重程度的大规模实验结果。对石膏钢板复合板护套墙、定向刨花板护套墙、钢带支撑墙进行了检验。研究了两种不同强度的闪络后火灾条件以及类似于标准熔炉资格测试的 1 小时火灾暴露条件。此外，还进行了全尺寸家具厨房火灾实验以进行比较。结果突出了墙壁的热响应和后续性能的差异，以及墙壁对预损坏（例如地震期间可能发生的损坏）的不同敏感性。这些结果是为这些墙体系统提供脆弱性以应对基于性能的设计的现实火灾的更大努力的一部分。
