Abstract:
Adhesive connections provide numerous advantages in the context of structural applications, particularly when applied to metal adherents like steel. A wide range of materials can be employed to establish structural bonds between steel components, thereby demonstrating diverse mechanical characteristics and structural performance. This study incorporates epoxy resin-based adhesives for connecting steel plates in order to experimentally examine the potential of employing these adhesives for shear connections, as well as in the presence of bolts in the connection. The findings indicate that the inclusion of up to four bolts in conjunction with glue at the connection does not significantly increase the ultimate stress. In fact, it has an adverse impact on certain specimens, and odd specimens are identified in comparison to their counterparts. This refers to the uneven distribution of tension that bolts generate. Thus, it is adequate to establish the connection using only adhesive. In contrast, the capacity is increased by 60% and doubled, respectively, when six and eight bolts are added, in comparison to the use of glue alone. In addition, a three-dimensional finite element analysis is performed on the three types of experimentally tested connections using ABAQUS/Explicit software. The glue interface between two steel plates is modeled using cohesive and damage criteria. The results demonstrated that they are consistent with experimental findings.
