Abstract:

After the San Fernando earthquake of 1971, California's State Capitol Building was declared an earthquake hazard and vacated. It took the most extensive structural and architectural rehabilitation effort in U.S. history to restore this splendid building to good health. Because of the tough structural problems faced here, and the imaginative solutions developed, ASCE this year bestowed on this project a Special Achievement Award. Strengthening the building to resist earthquakes required removing all the old brick floors and interior brick walls and replacing them with reinforced concrete. In effect, the entire building was made rigid by a honeycomb network of interior shear walls and floors diaphragms. Other major structural steps that had to be taken to improve the building's earthquake resistance are described.
