Abstract

The purpose of this paper is to propose the structural characteristic factors (k_D) of moment-resisting steel frames(MRFs). Simplified single-degree-of-freedom (SDF) systems with two shear springs are used as analytical model. Two shear springs consist of column with elasto-perfectly plastic behavior and beam with lateral buckling behavior. For the analytical models, statistical properties of k_D are studied by seismic response analysis subjected to 118 accelerograms. This k_D factor depends on deformation capacity, strength ratio of beam and natural period of the structure. Based on the analytical results, this paper proposes simple formulae of mean value and coefficient of variation of k_D. Then, k_D factors corresponding to the story drift angle are calculated for five different types of MRFs by using SDF systems.
