This study dealt with the change in the clamping force of bolt in the friction joint depending on the sectional damage of bolt. Based on the study of the clamping axial force of bolt and sectional damage, clamping force of bolt was affected by sectional damage of bolt head. Thus, relationship between clamping axial force of bolt and corrosion damage of bolt should be considered for maintenance of steel structures.
