Product Performance

Using components to solve old challenges in new ways means time and cost savings for builders and framers—and an expanding business base for component manufacturers.

While the perception of floor vibrations is subjective from one person to the next, overall floor systems which exhibit lower deflections and less acceleration from vibration sources tend to be perceived better than other designs. To accomplish this, the designer may elect to do one or a combination of things, covered in this report.

Many potential complaints and problems can be mitigated by an astute truss technician during the design phase.

The first two Standard of Care articles discussed deferred submittals and truss-to-truss connections. This article explores truss minimum required bearing width issues from the perspective of the design community.

  • Plywood and OSB design values are given; those that are doing repairs in your office should have a good feel for the similarities and differences.
  • Plywood and OSB generally have similar design properties with a key exception of fastener strength where plywood will require more fasteners to be used.
  • If a truss repair specifies only OSB, plywood should not be substituted without written permission from the registered design professional who prepared the truss repair design drawing.
  • SBCA’s vision for a testing facility is to create new methods to value engineer structures.
  • Finding out about load paths through building components has been the focus of SBCRI’s work.
  • The ability to do forensic testing in SBCRI is a useful risk management strategy.
  • Standard metal connector plates are suitable for use in lumber with moisture content of 19 percent or less and in building applications with no exposure to corrosive substances.
  • Connector plates used in trusses exposed to high humidity or caustic chemicals may need to be treated to prevent corrosion.
  • A variety of protective coatings can be applied to truss places in situations where special protection is necessary.
