Back in the ‘80s, truss technicians had to input the lengths, bearing locations and any concentrated loads on a truss other than a standard truss.
Today’s truss design software helps streamline truss technicians’ work, but fundamental design, engineering and building code concepts are still important.
Design technology gives us the capability to take designs to the next level and spec in a wide range of products from wall panels to steel trusses.
The time has come to embrace all structural building component materials.
BCSI-B2 provides temporary bracing guidance for trusses spaced up to 24 inches on-center.
BCSI-B10 offers temporary bracing guidance for wide on-center trusses such as those used in post frame buildings.
Truss Designers note on Truss Design Drawings that truss top chords must be laterally braced by the roof sheathing to prevent the top chord from buckling.
When purlins are specified, check with the Truss Designer to determine the maximum unbraced length of the top chord between purlins to avoid top chord buckling.
The founders of our industry are probably asking, "Where’s my truss industry?"
We must continue to sell value in order to keep this industry strong.
One of the only possible negatives to selling more engineering and integrated services is if component manufacturers begin to dilute the value of components by not "up-selling" the value provided.
The Western Lumber Grading Rules permit combinations of like-named U.S. and Canadian species groups, which allows mills that have access to logs from the U.S. and Canada to mix them during production.
The most common combinations are Douglas Fir-Larch, Hem-Fir and Spruce-Pine-Fir.
The applicable design values for a given U.S. and Canadian species group combination that component manufacturers should use in their software are the lower of the two individual country values for each design value category (see Table 2 on page 76).
It’s time to reconcile your OSHA recordkeeping logs.
If an injury or illness resulted from an event or "exposure" that happened at work, assume it is work related.
There are some exemptions to what is defined as work related, such as an employee using company property for personal tasks outside his/her assigned work hours.
Generally, wall girders cannot be used in second story framing because it is nearly impossible to brace the compression top chord of a girder when it is placed in a wall.
The top chord(s) of girder trusses can experience very high compressive forces, which can cause the chord to buckle out of plane.
An in-plant quality control program helps you quickly identify issues with a press or how someone is doing their job through the management information that the data provides.
The program may take an investment in time and money, but monitoring the benchmarks and charts and catching a problem and solving it in a timely manner is well worth it.
Proof of such a program can potentially help lower your insurance premiums.
