The New 1988 SEAOC Blue Book and 1988 UBC Overview of Lateral Force Section

by Allan R. Porush, Dames & Moore,

Document Type: Proceeding Paper

Part of: Seismic Engineering: Research and Practice


This paper presents an overview of the lateral force section of the new seismic design provisions of the 1988 edition of the Uniform Building Code (ICBO, 1988), and the 1988 Blue Book (SEAOC, 1988). Although there are some nominal differences, the provisions in these two documents are essentially identical. The Blue Book - 'Recommended Lateral Force Requirements and Tentative Commentary' was developed by the Seismology Committee of the Structural Engineers Association of California. The UBC, published by the International Conference of Building Officials (ICBO), has incorporated the new SEAOC recommended provisions.
