Abstract:
Although live load vibrations of concrete structures are generally not an issue, on rare occasions, human perception of vibrations in a concrete structure is of paramount concern. This was the case for the renovation of the Campus Recreation Center at the Georgia Institute of Technology, in Atlanta, GA. The structure consists of long-span post-tensioned concrete frames and slabs that span swimming and diving pools constructed for the 1996 Olympics and create a new fourth floor for the facility. The peer review of the facility, in which the new floor was modeled to determine if activity-induced vibrations would be an issue, is discussed.
