Installation Best Practices

Truss Bracing: Which Would You Rather Install?

A full-scale truss bracing demo was an eye-catching feature of the BCMC 2017 show floor.

Installation Information at Your Fingertips

For decades, SBCA Jobsite Packages have helped component manufacturers (CMs) provide handling and installation guidance to their customers with every order. These pre-assembled packages of instruction documents, attached to truss deliveries in a zippered plastic bag, are now available in a digital format.

Best Practices Provide a Best-Case Scenario

SBCA’s library of technical design and installation best practices has been expanded over the past year to help CMs navigate a wide array of code-related challenges in their markets.

Installation Guidelines

Question: 

Are there any associations that have recommendations for the installation of wood trusses?

Gable End Bracing

Question: 

Is there a detailed table for gable studs that gives the maximum length a vertical member can be before a lateral brace is required?

Bracing Schematics

Question: 

Are there any schematics available on how to horizontally brace a 7/12 pitch roof?

Jack Truss Connections To Girder

Question: 

In a hip roof application where jack trusses connect to a girder truss using pressure blocking (power blocking), what is the proper installation and the span that is acceptable before a hanger is required?

Fire Rating For Truss Assemblies Built With 2x3 Lumber

Question: 

Are there any published studies or guidelines on the fire rating of floor trusses built with 2x3 lumber?

Fire Cuts

Question: 

What type of construction uses a fire cut truss? Could you describe a fire cut truss?

Penetration Of Fire Walls

Question: 

Can a roof truss penetrate a one-hr. tenant separation wall without having a one-hr. rated ceiling? The building official insists that the 2x4 chords are combustible and nullify the integrity of the one-hr. rated partition that is constructed in an attic above an 8 in. C.M.U. bearing wall. The partition consists of gypsum board attached to 2 x 4 stud framing. The building official insists that a ledger must be attached through the gypsum board to support the trusses each side of the wall. This is almost saying that any rated assembly must have bearing only on other rated assemblies.
