A 10,000 square foot addition to an existing warehouse building, The Community Food Co-Op in Bozeman, Montana combines numerous steel and wood features with existing masonry. Due to the openness of the building, the lateral force resisting system consists of a series of large steel moment frames with wood shearwalls. The roof system is a combination of timberframe wood trusses and sandwich panels. The upper floor is concrete on steel bar joists supported with open span steel beams. The exterior porch roof and floor are supported with thirty foot tall steel “mast” columns and steel rods forming a unique support system.
A new four-story building with 38,500 square feet of usable space for ski lodge activities such as ticket sales, cafeterias, classrooms, locker rooms and a day care center. The building will be constructed into the side of a mountain with two stories below the backside grade. The foundation is cast-in-place concrete walls. The floor levels are framed with steel beams and girders with a concrete-filled metal deck. The roof has a 6:12 slope with some dormers. The roof framing is steel purlins with wood rafters and wood sheathing. The exterior walls are wood in-fill studs of the steel frame. The interior walls are light gage steel in-fill studs. The lateral force resisting elements are a combination of steel moment frames, steel-braced frames, concrete shear walls, wood shear walls and heavy timber bracing.
The gigantic timbers that make up the timber trusses of the main living area are the focal point of this residence – visually and structurally. The truss bottom chords are composed of two 10 inch wide by 24 inch deep timbers. The bookends of the main portion of the house are 45 foot tall masonry chimneys which are wrapped in a real stone veneer and weigh nearly 65 tons a piece. Two concrete grade beams run the full length of the home under the lower level floor and provide lateral support for the chimneys in case of a seismic event. At the far end of the house a three-story tower provides a vantage point to view Whitefish Lake from the rooftop level. The tower is circular, 20 feet in diameter, 35 feet tall, and wrapped in a 6” thick stone veneer. A steel frame skeleton provides structural stability for the tower.
The house is approximately 20,000 square feet and has four stories that overlook Flathead Lake. It is built into the side of a mountain, thus creating a two-story daylight basement. There is a four-car garage, a 22-foot tall swimming pool room, and over 4000 square feet of exterior decks and balconies.
