Fire test results including the time–temperature and deflection profiles are presented along with the failure times and modes. reinforced concrete column as shown in Figure 1. This paper presents the details of the LSF wall tests and the thermal and structural performance data and fire resistance rating of load-bearing wall assemblies lined with varying plasterboard-insulation configurations under two different load ratios. They demonstrated that the use of insulation externally in a composite panel enhanced the thermal and structural performance of LSF walls and increased their fire resistance rating. These tests showed that the use of cavity insulation led to inferior fire performance of walls, and provided supporting research data. It has been accepted for inclusion in International Specialty Conference on Cold-Formed Steel Structures by an authorized administrator of Scholars Mine.

In this research 11 full scale tests were conducted on conventional load bearing steel stud walls with and without cavity insulation, and the new composite panel system to study their thermal and structural performance under standard fire conditions. A new composite wall panel was recently proposed to improve the fire resistance rating of LSF walls, where an insulation layer was used externally between the plasterboards on both sides of the wall frame instead of using it in the cavity. Figure 1-1 The Brick Veneer Over Steel Stud System. 1-1 shows a typical brick veneer on steel stud installation. A brick veneer wall consists of an exterior wythe. Load Bearing Wall Systems Construction Guide Uneven Plank Having a solid, level surface is cri cal for load bearing metal framing. and the cold formed framing industry have published guidelines and recommendations for.
takes into account the wall’s insulation R-Values but also factors in the framing member’s impact on wall’s overall thermal performance. However, there is limited data about their structural and thermal performance under fire conditions while past research showed contradicting results about the benefits of using cavity insulation.

Light Gauge Steel Framing (LSF) walls made of cold-formed and thin-walled steel lipped channel studs with plasterboard linings on both sides are commonly used in commercial, industrial and residential buildings.
