Load Table Changes for Joist Hangers

CodeWatcher Simpson Strong Tie catalog

Construction professionals designing projects in states adhering to the 2015 or 2018 I-Codes should check existing product load tables against these updated load values.

Both the 2015 and 2018 IBC and IRC require manufacturers to test joist hangers and similar products to a new standard, ASTM D7147. In response, Simpson Strong-Tie re-evaluated all of its related wood connectors to meet the new test standard.

The new 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% – up or down – are indicated in red in the product load tables.

All Simpson Strong-Tie connector IBC code reports have now been updated to the 2015 IBC, and 85% 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 these updated load values. While these load changes do not affect completed and permitted projects, Simpson Strong-Tie recommends using these new values going forward.

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 the company’s Connector Selector® software and Joist Hanger Selector web app. (This software will be updated with the new allowable loads by the end of March 2019.)
