This study focuses on the variability of the dynamic response of jointed structures. It is well known that the dynamic response of joints is prone to variability issues when they are open and closed again. This paper will present one numerical example and two experimental ones on different type of structures used for studying this issue of variability. The numerical example will focus on parameters such as torque magnitude and contact area. The analysis, which is linear, will present the changes of natural frequency caused by the variation of these two parameters. The experimental examples will focus on parameters like torque magnitude, torque sequence and number of assembling. Both natural frequency and damping changes will be measured from a number of repeated sequences and analysed using statistical methods.
