Codification of Precast Seismic Structural Systems
A systematic program to develop innovative seismic-force-resisting precast structural systems was initiated by the Precast/Prestressed Concrete Institute (PCI) and the National Science Foundation (NSF) in 1990 and culminated with the testing of a five-story 60%-scale building in 1998. In 2003 the American Concrete Institute (ACI) completed the codification of one of the precast systems used in that building, the hybrid frame. This paper summarizes the research, analytical and experimental work that went into developing ACI's hybrid frame provisions and the progress towards codification of the other primary seismic-force-resisting system used in the building—one consisting of unbonded post-tensioned vertically coupled shear walls.
