The Stillwater Stamford
Structural design of new 4-story multi-family building with partial basement level parking in Stamford, CT.
The Stillwater Stamford is a new 4-story multi-family wood on concrete podium slab building with partial basement level parking below in Stamford, CT. The at-grade drive aisle passes under the north end of the building, where there are 3 stories of wood above transferring onto a slab on metal deck. This drive aisle allows access to the below-grade garage at the rear of the building. The ceiling of the garage is a two-way flat transfer slab picking up the 4 stories of wood trusses and bearing walls above.
The remaining superstructure consists of open web floor and roof trusses with TJI's crossing the center corridor. The exterior and corridor walls are 2x6 construction, while the demising walls consist of (2) 2x4 walls with a minor gap between them to reduce sound transmission.
20” deep floor trusses span unit to unit and 24” deep flat roof trusses span exterior wall to corridor wall. A 2-stage lateral analysis was conducted of the wood shear walls landing on the podium slab, which in turn is supported by concrete shear walls and columns.
