Abstract: The present invention provides a method for designing a strong column and weak beam of a steel frame beam-box column under bidirectional earthquake actions, including the following steps: designing an initial frame; defining important beam-column joints and important sections at a designed axial compression ratio according to a calculated result of a response spectrum CQC method of the initial frame; unifying bidirectional COF values of the important beam-column joints; determining a degree to achieve the strong column and weak beam and proposing two quantifiable evaluation indexes P1 and P2; performing statistics on a damage index D of the frame after an elastic-plastic time-history analysis of a plurality of selected groups of natural waves, and acquiring a parameter frame meeting a target yield mechanism via the statistics performed on the damage index D in combination with an evaluation standard provided by the present invention.
