Keyword: Wood Trusses
Bolted wood trusses were used as roof supports for the Warm Springs facility. Settlement and some lateral movement related to the trusses was noted in some window
wall and interior finished areas.
The wood in large bolted trusses has a tendency to shrink with age as it driesout and the bolted connections will show minor displacement.
During the first several years a preventive maintenance plan of periodic inspection and tightening of the bolted connections should be adopted. If excessive vertical
displacement is noted the truss can be jacked in place before tightening the bolted connections.
