Uniform Building Code 1997: Equivalent Lateral Force Method

Abstract

Several seismic building codes are currently in use in different regions of the United States. The International Building Code-2000 (IBC-2000) and The Uniform Building Code—1997 (UBC-1997), published by the International Conference of Building Officials, are the building codes most extensively used, particularly in the western part of the country. In addition to these building codes, two other major building codes are used: 1) The BOCA, or National Building Code [Building Officials and Code Administrators International 1999]; and 2) The Standard Building Code, of the Southern Building Code Congress International (1999).
