This paper presents a numerical study on the column-to-beam strength ratio that affects the seismic energy dissipation of beams and columns in fish-bone-type steel moment frames. The major parameters are number of stories, strengths of columns and beams, and ground motions. The seismic energy dissipation is classified into two categories: energies contributing to story mechanism and total mechanism. The following conclusions are obtained: (1) It is suitable for the column-to-beam strength ratio to be defined by the total of the strength of the beams and columns at a node for evaluating the seismic response; (2) As the column-to-beam strength ratio increases from 1 to 1.3, the energies contributing to story mechanism decreases significantly in the most cases.
