Resumen:
The unsatisfactory performance of modern structures designed according to current seismic design codes has raised some concern in the international community of structural engineers. Due to the large economical losses derived from recent seismic events, design methodologies that are based in the explicit control of the dynamic response of structures have been formulated. This paper introduces, within the framework of performance-based design, a numerical methodology for the seismic design of structures that are expected to undergo severe cumulative plastic demands. The methodology explicitly considers and integrates: 1) the structural and non-structural performance of the building, 2) the life safety limit state, and 3) the prevention of low cycle fatigue.
