Abstract:

Seismic design requirements for nonstructural building components of five major building codes, including the 1994 Uniform Building Code, the 1994 Standard Building Code, the 1994 NEHRP Recommended Provisions for Seismic Regulations for New Buildings, the New Zealand Building Code, and the Japanese Building Code, were reviewed in this study. Comparisons of codes reveal wide variation in seismic force and displacement requirements, both in terms of levels of stringency and levels of details. The difference in seismic force requirements between the most and least stringent codes can be more than five times. The study also found a lack of focused investigations, dedicated to mitigating seismic damage to nonstructural building components, even though widespread damage to nonstructural building components continues to be observed in recent earthquakes. Based on the findings of this review, areas of needed research were identified.
