Oregon State University’s Peavy Hall features an all-wood design that uses cross-laminated timber (CLT) in a unique way called post-tensioned tilting shear walls. In addition to resisting the lateral forces subjected to the building by the wind, the walls are designed to be able to withstand the most significant seismic events and snap back into place without losing structural integrity.
In addition to the CLT bracing walls, Peavy’s main structure uses CLT floor panels and glulam beams and columns. Other secondary applications of CLT include atrium stair stringer, exit stair railings, and exterior canopy roof structures.
The ultramodern replacement building reinforces OSU’s international status as the premier forestry college. The three-story, 80,687-square-foot replacement of Peavy Hall relates directly to Richardson Hall. In addition to the CLT, the structure was built with a combination of glass and acoya treated wood and houses innovative classrooms, laboratories, offices and meeting spaces.
Peavy Hall now offers a transformative educational experience in a range of forestry and natural resources degree programs. The appearance and atmosphere of the complex will enhance OSU’s stature in the fields of forestry, natural resources and wood science research and education.
Given the time of year that the timber structure was being erected, the emphasis was on moisture control with respect to the timber elements, as well as a detailed plan for drying the structure prior to installation. pour the interior finishing slabs. Some of the main goals were to reduce swelling and checking of wood elements, as well as to limit staining on finished panels.
Early coordination took place to assess each product used on the project in order to come up with a detailed approach meeting each unique requirement. After the roof was finished, the timber elements were slowly dried in a process that involved regular testing of temperature and moisture content.
