Effect of Circular Bolt Pattern on Behavior of Extended End-Plate Connection
Publication: Journal of Structural Engineering
Volume 139, Issue 11
Abstract
The behavior of extended end-plate connections with a circular bolt pattern under static and cyclic loads is investigated. Twelve three-dimensional numerical models were developed and analyzed using the FEM, and the results of the connections with a circular bolt pattern were compared with those with a traditional square bolt pattern. The effects of various bolt diameters and end-plate thicknesses on the bolt-force distribution of each bolt pattern are investigated. The results of this study showed that the circular bolt pattern can enhance the moment capacity, reduce pinching, and ultimately increase the energy dissipation of the connections depending on their geometric parameters.
