American Wood Council Updates Connection Calculator


The American Wood Council recently released an updated version of its free Connection Calculator tool based on the provisions the National Design Specification for Wood Construction as referenced in the 2015 International Building Code.

The updated calculator includes cross-laminated timber connection provisions and post-frame ring shank nails.

According to AWC, the Connection Calculator provides users with an app-based approach for calculating capacities for single bolts, nails, lag screws and wood screws. It offers a way to determine both lateral and withdrawal connection values and includes adjustment factors for temperature, wet service, varying load durations and end grain.

Additionally, single- and double-shear capacities can be determined, as well as wood-to-wood, wood-to-concrete and wood-to-steel connections using a variety of solid sawn lumber, glulam, and CLT species and wood structural panels.

For connections loaded in shear, the organization notes that the calculator presents results for each of the NDS-prescribed yield modes and calls out the controlling result.

“Modern technology helps simplify our daily lives in many ways,” said Bradford Douglas, P.E., AWC’s Vice President of Engineering.

“Now, today's technology plays an important role in the way the wood construction industry is improving speed, efficiency and safety, and even compliance with the latest building codes and standards.”

The updated Connection Calculator is available as a Windows 10 application, as well as a download on iOS and Android devices.
