Abstract
In the current study, the influence of beam and column dimensions on the seismic response of joints is numerically evaluated by changing beam and column dimensions in ABAQUS. Three wide column-beam joints were modeled and verified using the experimental studies available in the literature. Dimensions of verified models were then changed to evaluate the effect of element dimensions on the parameters including ultimate moment, ultimate shear and ultimate rotation. Variable parameters were the ratio of column width to beam width, Cw/Bw, the ratio of beam width to beam height, Bw/Bh, and ρ of column. It was concluded that by decreasing the ratio of Cw/Bw, both of ultimate moment and ultimate shear decreased. Additionally, by increasing the ratio of Bw/Bh, both of the ultimate moment and ultimate shear fluctuated. Moreover, by increasing ρcolumn, ultimate moment fluctuated, whilst ultimate shear increased. It was also indicated that by changing the variable parameters, ultimate curvature fluctuated.
