The Simpson Strong-Tie 2019–2020 Wood Construction Connectors catalog, a guide to its innovations and product line expansions for wood construction applications, is available in print and online.
The catalog features updated connector allowable load tables to meet ASTM test standards required by the 2015 and 2018 International Building Code (IBC). It is designed to assist engineers, architects, designers and contractors in selecting the right products for performance, efficiency and productivity. And in an ongoing effort to ease inventory management for pro suppliers, it has streamlined product line offerings.
The catalog features more than 14 new products and product line extensions, including additions to the Outdoor Accents collection of decorative hardware, the MPBZ moment post base and BT brick tie product lines. To simplify product specification, Simpson Strong-Tie has eliminated redundancies to help customers choose the right product, and has moved a portion of specialty items to the website in order to further streamline the catalog and provide for an enhanced user experience both in print and online.
“Every two years, we do a comprehensive review of and complete update to our Wood Construction Connectors catalog to make sure our customers have the latest information on our newest innovations as well as any changes related to building codes or new testing,” says Simpson Strong-Tie vice president of Connectors and Lateral Systems, Sam Hensen. “We know, and appreciate, that this catalog is a one-stop resource guide for our contractor and specifier customers when they are selecting the best hardware for their needs.”
Important Load Table Changes
Both the 2015 and 2018 IBC and the International Residential Code (IRC) require manufacturers to test joist hangers and similar products to a new standard, ASTM D7147. Simpson Strong-Tie has worked to re-evaluate all of its related wood connectors to meet the test standard. The 2019 Connectors catalog reflects this work in the updated tables for allowable loads of connectors used for wood-to-wood, wood-to-concrete, wood-to-masonry and wood-to-steel connections. Allowable loads that changed more than 5 percent, up or down, are indicated in red in the product load tables. All Simpson Strong-Tie connector IBC code reports have been updated to the 2015 IBC, and 85 percent of those connector reports have been updated to the 2018 IBC.
Construction professionals engaged in designing current and future projects in states adhering to the 2015 or 2018 I-Codes should check existing product load tables against our updated load values. While these load changes do not affect completed and permitted projects, Simpson Strong-Tie recommends using these values going forward. To view the ICC code adoption map, click here. (Note: You’ll need to click on each state to view the code adoption details.) Check with your local building officials to ensure acceptance.
Current projects in jurisdictions using 2012 or older building codes can reference the load values in the 2017–18 Wood Construction Connectors catalog and use the current versions of our Connector Selector software and Joist Hanger Selector web app. (Note: This software will be updated with the new allowable loads by the end of March 2019.)
