摘要

Non-uniform values of recurrence intervals to seismic failure of structures are shown to occur for different limit states. The median capacity and the capacity and demand factors specified by currently accepted criteria are calculated for a set of 5-, 10-, 15-, and 24-story buildings, built on very soft soil sites and exposed to narrow-band ground motions. Using these values and the demand hazard curves for each structure, the recurrence intervals to failure are obtained for serviceability, life-safety and near-collapse limit states. Based on the results, it is concluded that for the design of structures exposed to the action of narrow-band motions, it may be appropriate to use capacity and demand factors that depend on their fundamental periods of vibration.
