This new eleven-story reinforced concrete residential building was developed by Equity Community Builders. It includes two levels of parking, one at the lowest level (Delancey Street) and one at the fourth level (Bryant Street). The remainder of the floors contain a total of 38 units. The floor and roof slabs are post-tensioned. The seismic system consists of concrete shear walls around the stair and elevator cores. Below the fourth level, the exterior retaining walls also act as shear walls to contribute to the system. |
|
A mechanism-based seismic analysis was used to determine the areas where yielding will occur in the shear walls, and special detailing was used to assure ductility in these areas. |

| The project included an exterior public stair from Delancey Street up to Bryant Street. Exposed steel was used for the rails, as well as for exterior architectural details on the building. |  Photo by Mark Nienberg |
