People always ask how about the use of the precast/prestressed concrete components in the high seismic region. It can be informed in this occasion that on August 9, 1999, The University of California - San Diego had an experimental program for their PRESS Research (Precast Seismic Structural Systems). It is to view the seismic testing of a five-story precast, prestressed concrete frame and shear wall building. The preliminary result is that in general the seismic frames performed very well with the base shear continuing to increase even at a maximum drift. The performance of the prestressed frame was particularly good. Damage to beam-column connections was minimal in all frames. The results obtained from this research will be used to develop design guidelines that emphasize the inherent advantages of precast, prestressed concrete system in various seismic zones. These guidelines can then be incorporated into various building codes.
