These tested assemblies are available for specification by Architects or Building Designers, and for use by all Truss Manufacturers where a rated assembly is required, and can generally be applied to both floor and roof assembly applications. Unless otherwise noted, all IBC references are from the 2012 version.
Trusscore Fire Rating & Performance - Trusscore
Trusscore Wall&CeilingBoard has a "Class A" fire rating — the best available — with a flame spread index of 10 and smoke developed index of 380. Fire-resistant walls contain fire to a room and prevent it from spreading into an adjacent room for a designated time.
2017年10月2日 · Fire resistance ratings of materials and assemblies are not always readily available from prescriptive tables and tests. Theoretical methods offer an alternative to full scale fire tests. Current versions of the International Building Code also offer guidance regarding fire-resistance ratings.
If a fire rated assembly, rather than draftstopping, is required within concealed attic spaces, the following details show approved one-hour and two-hour rated assemblies that may be used in the roof cavity and that may be constructed with gable end frames or trusses. Figure 17.3.3 UL - U338 1 hour rated wall - bearing or non-bearing - with
The rated walls in this guide were designed to retard fire from penetrating walls and advancing into an adjacent floor system or a floor/ceiling space above. These wall designs address fire-blocking requirements for concealed spaces in
Determining Fire Resistance | SBC Magazine
The fire-resistance rating of a wood frame assembly is equal to the sum of the time assigned to the membrane on the fire-exposed side, the time assigned to the framing members and the time assigned for additional contribution by other protective measures such as insulation.
Fire-rated assemblies: Stark Truss SI Series I-joists have been shown through testing and engineering analysis to achieve the fire resistance ratings described in this report.
