This study is aimed to present the development of Finite Element (FE) Model to predict the elastic and inelastic response of the interior steel beam-column connections of the moment-resisting frame. First, the finite element (FE) model of welded unreinforced flanges-bolted web beam-column connection (FEM1) was developed and analyzed. The inelastic analysis results of FEM1 model included material nonlinearity and cyclic loading scheme were verified with an available full-scale connection tested at the University of Michigan. Guided by FEM1, fifteen FE models representing interior connections of the moment-resisting frame were developed. The FE analysis of this connection was aimed to investigate behavior and potential of such a type of the beam-column connection subjected to an earthquake.
Since from other studies show that the panel zone portion of columns can dominate the inelastic response of a moment frames. Therefore, the analytical results were focused on the behavior of panel zone.
The analytical results from first part (FEM1) showed such excellent agreements with the experiment, globally and locally. The high von-Mises stress regions exceptionally matched yielding areas of the tested specimen. Based on FE analysis, the loading resistance and panel zone rotation of fifteen connections show well capture behaviors of the panel zones. The connections with a weak panel zone strength can rotate more compared with strong one resulting in severe yielding of the panel zone. On the other hand, the beams of connections with the strong panel zone result in severe damage in the connection area between beam flanges and column flanges including the shear tab and the beam web bolted to it. In conclusion, the FEM developed from this study can use to analyze the steel moment connection with the details of as shown. |
