In the design and development stages of mechanical structures, one of the most challenging part is modeling joints, due to their complex dynamic behavior. In this study, a structural modification method is used to determine the linear dynamic characteristics of a mathematical model representing a bolted joint connecting two beams. A simple formulation, based on a structural modification method, is suggested to represent a bolted joint with a complex stiffness matrix. The method proposed is verified by using simulated experiments. As the method requires the measurement of only the assembled structure, not individual substructures connected with a bolted joint, it is observed that this approach is less sensitive to measurement errors, compared to identification methods using substructure decoupling.
