Recent work in understanding bolted interfaces in dynamic loading has led to a coordinated effort of structural dynamic model validation of the connections using experimental responses. Two phases of experiments were performed on a bolted connection with stiffness and energy dissipation properties which were isolated from the rest of the experiment. Early experiments were used to calibrate analytical models and later experiments were used to provide responses for model validation. Both modal-type experiments and electrodynamic shaker driven experiments were used to exercise the joint over the range of its intended interface load levels. Performing clean and simple experiments that isolated behavior of the joints from the stiffness, damping and boundary conditions of the rest of the experiment is a challenge. Techniques that yield data to provide a sound basis for bolted joint model calibration and validation are described.
