Energy approach in peformance-based seismic design of steel moment resisting frames for basic safety objective

Abstract

This study presents an energy approach to the performance-based seismic design of steel moment resisting frames for the basic safety objective. The seismic demand is expressed in terms of hysteresis energy and its distribution along the height of the frame, based on an associated study. The resistance of a steel moment-resisting frame to such demand is presented in the form of energy dissipation capacities of critical members, based on the previous experimental studies on full-scale moment-connections. An energy-based design methodology is proposed for performance-based earthquake resistant design. The proposed design method is examined using design examples and the results are discussed.
