Describes the design and construction features of a 23-story concrete frame building built in San Diego, part of Seismic Zone 3, the highest intensity area in the United States. The building was approved before a 13-story restriction was adopted. An interesting feature is the use of columns twisted 60 deg between the seventh and eighth floors.
