Abstract

Designing detachable joints between I-section beams and tubular section columns is not a straight-forward task. This arises from the fact that placing bolts inside the hollow section of the column can sometimes be challenging due to the inaccessibility of its interior. In response to this issue, the research community has put forth various types of connections, including bolted joints with welded studs. These are of particular interest due to their ease of execution on the construction site and their ability to be disassembled. This article presents an analytical model based on the components method to estimate the stiffness of beam to column joints and column to base plate joints with welded studs. These equations have been validated through a comparison with results obtained in full-scale experimental tests. The findings demonstrate that the stiffness can be estimated using the proposed equations with a reasonable level of accuracy.
