Paper Number: ISOPE-I-12-055
... ABSTRACT The focus of this article is the evaluation of the traditional method of time domain analysis regarding its assumption that the maximum stresses of the structural members appear at the same time and specifically, at the time of the base shear maximization. Two procedures are followed...
