| Research Abstract |
The objective of this research is to establish reliability-based seismic design method. In order to achieve this objective, demand deformation capacity of a frame should be estimated. In this research, a seismic hazard model of an inelastic oscillator is proposed using an equivalent linearization technique and a uniform hazard spectrum. Also the equivalent linearization technique is improved by modifying the equivalent natural period. Finally, as the first step to the practical reliability-based design, load and factor design format is proposed for serviceability limit state design. Based on the investigation of the applicability of existing method for estimating load and resistance factors a revised practical method is proposed.
