The unsatisfactory performance of some 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 seismic design numerical methodology that integrates the predesign and local design steps, and that considers the following aspects: 1) the structural and non-structural performance of the building, 2) a dual approach that considers the service and life safety limit states, and 3) regarding the life safety limit state, low cycle fatigue through the use of cumulative ductility spectra, and the effect of degradation of the hysteretic cycle in the definition of strength and displacement spectra.
