Engineered Wood Products

A family team known for launching and selling home-construction companies is rolling out its newest venture, Hanover Family Builders, with nine communities in Osceola and Lake counties.

This presentation seeks to explain how to correctly apply live loads to the bottom chord of trusses for uninhabitable attics in accordance with IRC Table R301.5 and IBC Table 1607.1 and ASCE 7-10 Table 4-1.

This presentation provides an overview of fire-rated assemblies that include wood trusses. Topics covered include assembly testing, Harmathy’s rules, and an examination of fire performance in the field. 

Question: 

We are building a garage with a bedroom and bathroom and trying to find out what type of floor joists and roof trusses to use. The garage will be a 26 ft. by 32 ft. with a 26 ft. by 32 ft. room upstairs. But we don't want to have posts in the middle of the garage to help support the weight of the second floor.

Question: 

Is it the responsibility of the truss manufacturer to provide a sealed layout drawing for roof trusses?

Question: 

I am thinking of using wood trusses for the roofing/ceiling structural systems on some houses I shall build. I remember, though, an engineer/volunteer fireman commenting back in 1989 that the connector plates are prone to expand and pop off, early on in a fire, causing catastrophic structural failure. Was this the case, and if so, has this problem been corrected?

Question: 

We have been specifying laminated veneer lumber (LVL) beams for some time now. The plans usually state, “Beam to be engineered and supplied by truss manufacturer.” What kind of liability issues do I need to watch out for?

Question: 

I have mono trusses on either side of a firewall. I have the fire rating/wall material between them. Can I place a ridge vent above these two? Or should I use vents? How do I calculate the appropriate vent sizes and styles?

Question: 

In RC 2601, is RC-1 Channel used?

Question: 

We have a local builder wishing to use floor trusses with a 2-hour assembly. I have shown him the 2-hour design on pages 17-27 of the second edition of SBCA’s Metal Plate Connected Wood Truss Handbook. Is this assembly UL approved? If so, what is the design number?
