If knee braces are shown, the trusses must be designed for them using the loads provided by the RDP.
In the Midwest knee braces are used in many post frame buildings for which an RDP is neither required nor involved.
This rapidly forces the Truss Designer into the position of designing building elements that ought to be specified by the person responsible for the overall building design.
The relatively short spans and light end reactions associated with most jack trusses makes toe-nailing an efficient and effective attachment method.
An open end jack truss (see Figure 1) meeting the same design parameters would perform in a similar manner as a rafter and ceiling joist and generate comparable reactions. The top chord and bottom chord of the jack truss should correspond to the rafter and ceiling joist tables provided in the code. For these situations, the nail connections specified by the code are also applicable to jack trusses.
There is one largely untapped resource where manufacturers can make huge improvements in material handling— their suppliers.
Follow the journey lumber takes through your plant from when it’s unloaded from the truck and proceeds to the saw to the press to the staging area. Every second counts.
Talk to your peers to see how they address material flow at their plants.
Pre-start checklists can be likened to regular maintenance on your car at a “quick lube place”—fast and necessary.
Having all of the safety hazards in order while managing your maintenance scheduling means that pre-start checklists will actually save you time in the long-run, and they may even save one of your employees from a possible injury, too!
Attending BCMC allows attendees to see the latest technology that could be incorporated into their equipment replacement programs.
Manufacturers indicated that BCMC was the best place for an exclusive look at how they can gain the benefit of having all exhibitors in one place as a resource when creating a maintenance program or weekly, monthly or quarterly checks.
Without the diagonal brace, the only thing the lateral member(s) ensures is that the webs to which they are attached will be-have as a unit and buckle together in the same direction if and/or when the buckling load is reached.
The single diagonal brace and web reinforcement options satisfy the need for bracing individual trusses and truss members, but not the stability bracing of the entire building system.
BCSI-B3 Web Member Permanent Bra-cing/Web Reinforcement provides indus-try recommendations and methods for restraining web members against buckling.
