Oregon State University, School of Forestry, Peavy Hall

The 80,000 SF T-shaped Peavy Hall combines exposed CLT solid wood floor panels with a thin concrete topping supported on 40ft double glulam-concrete composite beams. Equipped with new tools to validate dynamic performance with on-site testing, the design achieved wood-concrete composite panel spans of 36ft between beams, with a structural depth of just 14”.

The use of post-tensioned CLT rocking shear walls for the lateral system is a first in North America. This innovative solution significantly reduces lateral loads while providing a highly resilient immediate-occupancy solution. Embedded unbonded tension rods within the panels allow the base of the walls to rock in a seismic event, while energy is dissipated through strategically placed dampers.
