UBC SEISMIC SERVICEABILITY REGULATIONS: CRITICAL REVIEW

This study reviews how serviceability and ultimate limit states are implemented in the Japanese seismic code. The study also examines the rationale of the UBC (Uniform Building Code) minimum seismic force provisions, particularly regarding the serviceability requirements. The study then makes recommendations for drift limits and stress levels by formulating the requirements for the serviceability limit state. The study found that the UBC design base shear ratio is related to the inelastic design spectra for the ultlimate limit state; it does not represent the elastic design spectra for the serviceability limit state. The one-phase seismic design procedure used by UBC cannot ensure that the requirements of the serviceability limit state are satisfied in general. These and other study findings are discussed.
