Saiful Bouquet is the structural engineer for the new Children’s Hospital of Orange County (CHOC) Southwest Tower, a 9-story 320,000 sf building with a curved façade on two sides of the building, a bridge to the adjacent existing parking structure and a patient drop-off driveway under the building at the 1st Floor. The new medical office building will house a variety of outpatient services including an imaging department, ambulatory surgery center, rehabilitation gym, specialized clinics, and a research floor with wet-bench laboratory. The building is under the jurisdiction of the City of Orange with portions of the building meeting HCAI (OSHPD) 3 requirements.
The structural system consists of concrete slabs over metal deck supported by composite steel beams supported by steel columns. The seismic force resisting system for the tower consists of steel special moment resisting frames in the longitudinal direction and a dual-system in the transverse direction consisting of both steel buckling-restrained braced frames and steel special moment resisting frames. The moment frames utilize the proprietary “SidePlate” bolted moment connections. The entire building is supported on a shallow mat foundation.
