The Influence of Column-to-Beam Strength Ratio on Seismic Performance of Concrete Filled Tube Moment-Resistant Frames
The seismic responses of 6-storey frame structures which are designed by means of beam yield mechanism (BYM) and column yield mechanism (CYM) are compared by using pushover analysis and dynamic analysis. This paper discusses the influence of column- to- beam strength ratio on seismic performance of concrete filled tube moment-resistant frames and analyzes the probability of the column yield mechanism. The results indicate that the strength ratios between columns and beams in a layer are effective parameters and of great significance to form yield mechanism.
