Abstract

This paper is concerned with yield surface useful for the simplified dynamic model for 3-dimensional multi-story steel moment frames with eccentricity. The authors propose a couple of new expression of yield surface on simplified dynamic model for each story that consists of beams and columns. The yield surfaces of each story were examined through simple plastic analysis for the frame, which has multiple structural planes. To calibrate the validity of the yield surface, two kinds of frames, which consist of beam yielding mechanism and column yielding mechanism, were used. Adopting new expression of yield surface, a higher accuracy of results can be acquired.
