This paper describes and proposes a model for the force vs. elongation behavior of asymmetrical steel connections liable to bolt failure when subjected to quasi-static axial loading. Fourteen (14) connections were assembled with one bolt, varying the distance from the bolt to the edge of the clamping zone, and 14 connections were assembled with two bolts, varying the distance between bolts. The experimental results show that the axial force vs. elongation behavior of the connection is approximately trilinear. And while the connection stiffness is not sensitive to the bolt location in the clamping zone, the plastic elongation of the connection is. The model shows that the stiffness of the asymmetrical connection can be predicted by assessing the stiffness of the connection components using spring and beam elements, and that the load capacity of the connection can be predicted based on Coulomb’s dry friction theory and the shear capacity of the bolts.
