Evaluación del factor de comportamiento de la Norma Ecuatoriana de la Construcción para estructuras metálicas porticadas

In order to perform the above mentioned assessment, a set of archetypes representatives of the design space have been defined. These archetypes were designed according three different procedures: acceleration-based and displacement-based procedures and an energy-based alternative procedure. Results depict that some of the adopted values for the behavior factor does not fulfill the requirements of the methodology used, so the design is not able to guarantee an adequate performance of the buildings when they withstand destructive earthquakes.
