The dynamic response of a preloaded bolted joint is investigated when subjected to
harmonic excitation. The equations of motion of the joint are derived on the basis of a
realistic linear mathematical model, by using simple spring-mass system analysis. Solutions
for the joint response are obtained in the frequency domain in terms of the force and motion
transmissibility ratios between joint plates. Although the main emphasis of this study is
focused on the dynamic response of preloaded bolted joint as a criterion of design, the
