Mass Timber Roof Ingenuity
Rogue Credit Union Community Complex | Medford, OR
Overview
The Rogue Credit Union Community Complex building is a stunning hybrid mass timber building that boasts an impressive total area of 140,000 square feet. The Rogue Credit Union Community Complex mass timber project is an impressive building that features notable materials and design elements. The building includes 30 glue-laminated (glulam) columns, 15 hybrid trusses, and 88 cross-laminated timber (CLT) roof panels covering a 30,000-square-foot space that houses two pools (one recreational and one competition), tennis and basketball courts, a gym, and fitness classes.
The design underwent three iterations to achieve its final form. The initial iteration used CLT over bulky glulam trusses. However, further refinements were made in the second iteration, where a hybrid truss design was implemented, incorporating bridge cables as tension strands. Despite the advancements, the use of bridge cables posed challenges due to their extended lead time. As a result, high-strength steel rods replaced the bridge cables in the final design iteration, allowing for a more efficient construction process. Ultimately, the final design utilized high-strength steel rods, providing a robust and practical solution.

HYBRID BOW-STRING TRUSSES
The building's most notable materials are the glulam/steel hybrid bow-string trusses, which incorporate a 105'1" long glulam beam, making it one of the longest clear-span glulam beams used in a structure.
TENSION RODS
The building also utilizes 150 KSI high-strength steel tension rods/components, which are four times stronger than typical steel. To protect the steel components from the caustic pool environment, a Tnemec paint coating was applied. The use of these materials and design elements creates a unique and durable building that will stand the test of time.
