Alexander Salenikovich: At the Heart of Innovation – Integrating Bonded Rods into CLT for the Institut Quantique at the Université de Sherbrooke!
The Institut Quantique at the Université de Sherbrooke is a three-storey building combining mass timber and concrete, designed by Saucier + Perrotte architects. Its innovative two-storey timber structure features cross-laminated timber (CLT) walls and slabs supported by Peikko DeltaBeam steel beams. The entire system rests on a concrete base that includes a transfer slab. This innovative structural approach enabled large spans and impressive cantilevers without visible beams, allowing for a sleek, ultra-thin floor system.
A research program was carried out in collaboration with Professor Alexander Salenikovich of Université Laval to achieve a world first: the use of bonded rods in CLT to connect steel beams to the cross-laminated timber walls.
Professor Salenikovich’s contribution was also highlighted during a specialized webinar held on Wednesday, April 16, 2025, from 6:00 p.m. to 7:15 p.m. During this event, he presented the groundbreaking results of his research on the integration of bonded rods into CLT—a world first—applied in the Quantum Institute project at the Université de Sherbrooke. This revolutionary project merges mass timber and steel in a high-performance hybrid building.
Alongside Thibaut Lefort, a structural engineer with a background in architecture, Professor Salenikovich addressed key topics such as the technical challenges involved in integrating bonded rods into CLT, the testing methods used to validate this new type of connection, and the observed structural performance. Together, they explained how this unique solution enables efficient load transfer between wood and steel components while preserving the building’s clean, minimalist aesthetic.

Professor Salenikovich also discussed the development process of this technology, including interdisciplinary collaboration among engineers, architects, and manufacturers, and the importance of innovation in achieving the building’s performance and sustainability goals. The project reflects a growing trend toward hybrid wood-concrete-steel systems, leveraging the strengths of each material both structurally and environmentally.
The webinar generated strong interest from industry professionals, who saw it as a tangible example of the future of sustainable construction. Attendees praised the project’s rigorous, collaborative approach and the potential of bonded rods to redefine standards in wood-steel connections.
