Abstract:
Parametric Studies aiming to investigate the failure mechanism of conventional plate connections have been under the influence of interaction between bending anchor and shear. This study uses ABAQUS finite element software and considers both non-linear material behavior and non-linear geometric behavior. According to the results, for enhancing lateral stiffness, the appropriate solution would be to increase the thickness of angles instead of increasing the thickness of the bottom of the column. The reason can be the control of column scaling up at the connection of angle to the column and its bottom. In addition, lateral behavior of construction inelastic range is controlled mostly by the behavior of angle. However, inelastic behavior of structures is controlled by the interaction between angle and base plate. According to the investigation, it is recommended that lumped element models should consider the corner weld defects in the way of connecting angle to the column and its bottom.
