Seismic design requirements for nonstructural building components of five major building codes, including the 1994 Uniform Bldg. Code, the 1994 Standard Bldg. Code, the 1994 NEHRP Recommended Provisions for Seismic Regulations for New Buildings, the New Zealand Bldg. Code, & the Japanese Bldg. Code, were reviewed in this study. Comparisons of codes reveal wide variation in seismic force & displacement requirements, both in terms of levels of stringency & levels of details. The difference in seismic force requirements between the most & least stringent codes can be more than five times.
