Vertical Load Carrying System | Concrete slab (2" to 4" thick) on steel deck with welded metal studs, supported by distributed steel frame. The building is divided into 3 structures (east and west structures and center core) on a common base. |
Lateral Force Resisting System | Eccentric braced steel frames (EBF) with welded moment connections. In the longitudinal direction the EBF's are at the ends of the building. In the transverse direction the EBF's are at the ends of the core, east and west structures. |
Foundation Type | Concrete drilled piers (24" & 30" diameter, 15' to 26' deep) under each column and supporting a perimeter grade beam & slab on grade. |
Remarks | The building is only 3-stories high, but each story is more than 19' high and it can be considered as a mid-rise structure, rather than a low-rise. The building was designed in accordance with the 1984 UBC. Only the west structure is fully instrumented. |
