Dynamic Behavior of a Multistory Pyramid-Shaped Building
This report describes the experimental and analytical studies of the dynamic behavior of the Transamerica Building, a multistory pyramid-shaped steel structure, sixty stories in height, located in San Francisco, California. The 853 foot high building has a square plan, 174 feet by 174 feet and consists of a two-story high ground floor, a triangularly shaped tubular space truss around the perimeter between the 2nd and 5th floor levels and above this level, a moment resistance frame with the exterior walls sloping inward at an approximate ratio of 1 to 11. The upper 10 stories consist of an open-framed pyramid shaped structure which is not occupied. On the east and west sides of the building, starting just below the 30th floor, shafts project from the building which contain elevators on the east side and a stairwell and duct shaft on the west side. The experimental work consisted of both forced vibration and ambient strudies in which the natural frequencies, mode shapes and damping values are determined.
