本文研究了各种因素对石膏板保护的钢结构承重墙耐火极限的影响。对14个足尺钢结构立柱组合墙体的耐火性能进行了详细的试验研究。单排和双排钢螺柱配置与石膏板安装在每一个暴露和未暴露的侧面，并与和没有绝缘的空腔中，被认为是在实验程序。使用的绝缘材料是玻璃、岩石和干吹纤维素纤维。从实验程序的数据被用来确定的效果，螺柱间距，剪切膜，负载强度，弹性通道安装，绝缘类型和计量厚度的石膏板保护，钢柱墙组件的耐火性能的螺柱。研究结果表明，石膏板的保温类型和层数对钢结构墙体的耐火性能有显著影响。
This paper presents the effect of various factors on the fire resistance of load-bearing, gypsum board protected, steel stud wall assemblies. A detailed experimental study was conducted to evaluate the fire resistance of 14 full-scale steel stud wall assemblies. Both single row and double row steel stud configurations with installation of gypsum board on each of the exposed and unexposed sides, and with and without insulation in the cavity, were considered in the experimental program. The insulation used were glass, rock and dry blown cellulose fibers. Data from the experimental program are used to determine the effects of stud-spacing, shear membrane, load intensity, resilient channel installation, insulation type and gauge thickness of studs on the fire resistance of gypsum board-protected, steel stud wall assemblies. Results from the studies show that the insulation type and number of gypsum board layers have significant influence on the fire resistance of steel stud wall assemblies.
