The Analysis by finite element method on the model which is constructed by spring-beam element has been performed to obtain stress behavior of the bolt on tee flange. Some experiments are simultaneously carried out under the same condition of the above model. The following results are obtained : (1) On the axial stress of the bolt on the flange recived external force the calculated stress are consistent with the experimental results. (2) The bending stress parallel to the bolt axis decrease with the increase of distance from its under-head. (3) When external force are acting on the flange, the rate of increase for axial stress and bending stress of the bolt become lower in the following case ; i) the flange is applied with large tightening force and ii) the flange thickness become larger and iii) the distance from the application point of external force on the flange to the nutral axis of bolt is shorter.
