This paper deals with distributions of the contact stresses when a T-flange is fastened with tap bolts to a base which is large enough compared with the T-flange. In an analysis, by replacing a T-flange and a base with two finite strips respectively, the distribution of contact stresses is analyzed as a two body contact problem using two dimensional theory of elasticity. In order to know the distribution of contact stresses near a bolt hole, the contact stress between two hollow cylinders is analyzed using three dimensional theory of elasticity. In addition. the force ratio, that is the ratio of an increment of a bolt axial force to a load when the load is applied, is analyzed. Moreover, taking a bending moment caused in a bolt into consideration the maximum stress is also analyzed. For verification of analyses, experiments are carried out and it is shown that analytical results are in a fairly good agreement with experimental ones.
