After a three-year absence, Virginia Tech is offering its popular two-day course on topics related to wood construction. On May 17–18 in Blacksburg, VA, the Structural Design Topics in Wood Construction course will address wood truss design, in-service performance, and installation...

Previously, we’ve reviewed the top manufacturers’ defects according to a survey of In-house inspections. (See my April 2020 article, “How Do Your Manufacturing Errors Rank on the List?”, for the top ten items and ways to correct them.) While wane in the plated area topped...

In addition to allowable lumber stress limitations, parallel chord truss designs are also regulated by maximum permissible deflection-to-span and depth-to-span limitations. All of the following recommended limitations should be achieved to provide a quality roof / floor system and assure...

A Truss Design Drawing (TDD) includes specific information[1] for structural engineers and building designers: truss profile, plates, loadings, wind speed, codes, enclosure, exposure, reactions, deflections, materials, bracing, bearings, etc. The maximum reactions are the most important values...

In the last few years, Simpson Strong-Tie has heard from a number of structural engineers expressing frustration with the lack of performance data for shallowly embedded, post-installed anchors (shallow anchors). Engineers of Record (EOR) have identified a common application for shallow anchors...

MiTek, a building industry innovator and enabler, continues to uncover ways to improve efficiencies and transform the building industry with better building solutions. In its latest endeavor, MiTek has designed and built a custom piece of equipment to perform lateral-load testing on walls that...

Since the introduction of strength design for post-installed anchors in IBC 2000, determining the designed capacity of anchors has become increasingly complex. Dozens of variables, such as geometry, concrete conditions, and the specific properties of different anchor types, make a quick,...

In this follow up to our July webinar, Innovations in Strength and Versatility: Overview of the Strong-Wall® High-Strength Wood Shearwall, we answer some of the interesting questions raised by attendees. During the webinar, we discussed the new Simpson Strong-Tie® Strong-Wall...

In our January 2021 issue, Frank Woeste and Don Bender wrote, “Hybrid Lumber" Grade Stamps Require Special Attention. This article provided information on how to recognize hybrid grade marks and how to calculate hybrid lumber values for truss design. Included was this caution: A...

As a follow-up to our January 2021 All Things Wood article by Frank Woeste and Don Bender, “Hybrid Lumber” Grade Stamps Require Special Attention, we are pleased to report that additional information is now available for designers and code officials. The following article appears...
