Lateral Force Resisting SystemConcentric braced steel frames (chevron and single diagonal type) on the perimeter and near the center of the building. All brace diagonals are tubular and are filled with lightweight concrete.
Foundation TypeDrilled (30" and 36" diam.), cast-in-place concrete piers, 15 to 20 feet long under braced frames. Concrete spread footings connected by 3.5' tie beams and 5" thick slab on grade.
RemarksThe building was designed and constructed in accordance with Title 24 of the 1985 California Administrative code and the 1979 UBC. There are two 2-story adjacent buildings spearated by seismic joints; one is on the north side and the other is on the southwest corner. The building was instrumented as part of the OSHPD/CSMIP Hospital Instrumentation Project.
