New High Wind Guide from Simpson Strong-Tie


Simpson Strong-Tie has released a newly updated High Wind Guide to help engineers, designers, builders, and contractors quickly and easily select the best connectors for building resilient structures in high-wind areas. 

The High Wind Guide is now available in fastener and building solution provider’s online resource center alongside additional resources to help safeguard the structural integrity of homes and buildings during hurricanes, tornadoes, and other high-wind events.

The National Oceanic and Atmospheric Administration has predicted a busy 2020 hurricane season, with a 60% chance of above-normal activity, which translates to 13-19 named storms anticipated. With the frequency and forcefulness of tornadoes also on the rise, homeowners and building owners have incentives to retrofit existing structures to withstand high-wind events, and adding connectors is a straightforward and affordable solution for boosting structural resiliency from hurricanes and tornadoes.

Created as a complete handbook for designing and building in high-wind areas, the Simpson Strong-Tie High Wind Guide includes completely updated allowable load tables per AC13 (ASTM D7147) standards, crucial data for engineers designing structures to resist high-wind events. Extensive testing of multiple connectors in some cases has resulted in higher allowable loads, most notably for the popular H2.5A and H2.5T hurricane ties as well as for the Strong-Drive SDWC15600 Truss screw.

In addition, the updated High Wind Guide includes installation details, information on coatings and corrosion protection; is organized by framing condition, with products listed in order of increasing allowable load, and includes values for connections that use multiple connectors. 

“Engineers and builders are determined to find more efficient high-wind construction solutions and ways to safeguard structures from hurricanes and tornadoes,” says Simpson Strong-Tie engineering manager Bryan Wert. “Simpson Strong-Tie continues to work with academia and others in the construction industry to help builders create more resilient communities with strengthened structures that save lives during high-wind events. In short, build with the best to prepare for nature’s worst.”

For construction professionals looking for additional information on high-performance solutions for high-wind forces, Simpson Strong-Tie is hosting a free webinar Aug. 12 to review the updated High Wind Guide, detail connector load testing, and offer best practices for retrofitting and building in high-wind prone areas.
