This new six-story residence hall will house 148 students and incorporates exposed cross-laminated timber (CLT) slabs supported by structural steel framing in order to achieve the client’s lofty goals of beautiful design, environmental sustainability, and an aggressive construction schedule. The building was erected in only three weeks, exceeding initial expectations. This residence hall is the first hybrid CLT-steel frame of its kind in New England.
The structural system utilizes 5-ply CLT as the structural floor system, spanning between steel wide flange beams, which are in turn supported by wide flange steel columns.
Bi-directional span capability of CLT panels were used to create openings in floor system without the need for additional framing below the floor slabs. Additionally, the length and width of the panels were used to optimize the number of pieces and layout of the joints to facilitate a fast compressed construction schedule.
