ABSTRACT
The present study extends the advantages associated with rigid-plastic models to different typologies of steel-framed buildings under earthquake loading. To this end, new hysteretic relationships (as well as its corresponding integration algorithms) are proposed. It is shown that such rigid-plastic models are able to predict global demand response histories with
reasonable accuracy. Finally, this paper presents a brief discussion on the use of relationships between peak displacement and the plastic capacity of rigidplastic oscillators as a mean for obtaining the required structural strength given a target scenario.
