New Interactive Tool Can Assist Engineered Design of CLT Systems

The inclusion of a built-in database of CLT layups reduces manual inputs, increasing speed and accuracy of calculation reports.

ATLANTA, GA / ACCESSWIRE / September 5, 2023 / A new set of free-to-use design tools released by engineering consulting firm EQUILIBRIUM will greatly improve the speed and accuracy of engineering the design of structural cross-laminated timber (CLT) systems. The CLT Structural Design Tool by EQUILIBRIUM was developed in part with funding from the USDA Forest Service Wood Innovations Grants and the Softwood Lumber Board to support the work of the mass timber design community.

CLT Structural Design Tool is an Excel-based resource that can be used for the engineered design of CLT panels for a wide range of applications such as roofs, floors, and walls. The toolset contains a built-in database of all CLT layups with PRG 320 certification currently available in the marketplace, allowing the user to quickly input predefined layups using macros or via manual input. Once the layup and user-provided information such as loading are supplied, the tool automatically performs its calculations and design checks. The tool also verifies relevant design criteria such as strength (cold and fire) and serviceability (deflection and vibration). Designs can be performed quickly, and calculation reports are easily printed.

"CLT's use as a structural material in buildings is increasing exponentially, and for good reason," said Matt Kantner, PE, SE, Associate Principal at EQUILIBRIUM. "We wanted to create a tool for engineered design that keeps pace with the industry. This tool is reliable and takes the guesswork out of CLT design. It is straightforward, approachable, and transparent, which makes it a great tool for seasoned mass timber engineers and newcomers alike. A thank-you to our sponsors and partners, including the USDA Forest Service and Softwood Lumber Board, who provided funding; Holmes, who performed a peer review; and all the CLT manufacturers who reviewed the database in the tool for accuracy of their CLT products."

EQUILIBRIUM encourages the adoption of this toolset by structural engineering firms, material suppliers, architects, and others with an interest in CLT systems. EQUILIBRIUM pledges to support and update the tool for a minimum of two years to keep up with the rapidly evolving CLT marketplace.
