A Finite Element Analysis on Behavior of a T-stub Type Gusset Plate in Different Bolted Connection Configurations

Configurations play a crucial role in the mechanical behaviors of bolted connections in steel structures. This study provides a visual characterization of the influence of different configurations on the bolted connection by introducing three configurations, namely the collinear, rectangular, and circular bolt configurations. A popular T-stub type steel gusset plate is introduced, and three types of loading conditions are implemented. A three-dimensional numerical analysis is comprehensively developed in a linear elastic framework, followed by a mathematical derivation to interpret the results. Instead of a one-rules-all condition, the results imply that different configurations excel under different loading conditions. The study provides an instructive guidance in choosing the most effective bolted connection configuration in the practical field of resisting the corresponding primary loading condition for connecting different structural components.
