Required Strength of Column Joint of Bidirectional Steel Moment-Resisting Frames
According to current design recommendations in Japan, column joints of steel building structure are required to remain elastic under severe earthquake, even ultimate state of the structure is reached. However, the rules for designing column joint are mainly based on experience, and there is no previous research that focuses on the behaviour of column joints within bidirectional steel moment frame under severe earthquake.
This paper conducted numerical analyses with steel moment-resisting frames subjected to bidirectional ground motions to investigate the behaviour and required bending strength of column joints. Firstly, from the analysis results, factors that affecting the maximum bending moment at column joint have been revealed; moreover, the shortages of current design recommendations in Japan have been figured out. Secondly, the effects of column joint yielding on the seismic response of steel moment-resisting frames under bidirectional ground motions are considered, and the required bending strength of column joint has been examined.
