In this paper, a rational seismic design procedure is proposed for mid-to-low rise steel moment frames. The proposed method is different from current R-factor approach in that it directly uses available connection rotation capacity as a primary design vailable. To this end, the relationship between available connection rotation capacity and R-factor is defined and quantified using nonlinear pushover analysis; this relationship has been a missing link in current ductility based design. A step-by-step displacement-based iterative design procedure is then proposed and verified using inelastic dynamic analysis. |
