Building Component Safety Information (BCSI)

Trusses are engineered components that will perform as intended if installed correctly. However, those who are installing trusses are not always adept in deciphering truss layout drawings.

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

Question: 

Are wood trusses designed to be fall protection anchors that would support a worker should he fall?

Question: 

What are the requirements for installing “valley set” overlay roof trusses? I am interested in nailing and support conditions. Some engineers ask for the bottom chord of the valley truss to be ripped to match the roof pitch of the underlying trusses. Is this necessary?

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: 

How much OSB can be stacked on a floor deck without damaging the trusses?

Question: 

We are finding it difficult to design permanent diagonal bracing for scissors trusses. The truss is often only a few feet in depth, which does not provide adequate room for diagonal bracing. Has SBCA come up with recommendations for permanent bracing of scissors trusses?

Question: 

It is critical that permanent top chord bracing is supplied by proper nailing of the valley truss bottom chords to the carrying truss top chords, through purlins or properly installed rated roof sheathing. If the sheathing is not carried through under the valley framing, then the permanent top chord bracing must be supplied in another manner.

Question: 

How do I, as a truss manufacturer, adequately advise my customer against the dangers of 60 ft. and over truss span installations?

Question: 

Are there any trusses that are supported strictly by the wood itself without any mechanical connections such as brackets?
