The purpose of this study is a development of a simple design method of stress analysis of bolted joint applicable to the general case. The T-flange joint is modeled using spring-beam elements and analyzed with finite element method. A new spring-beam model of T-flange is made taking the part of thread engagement into consideration. Using this new model the relationship between the applied load and the stress in the bolt is analyzed. The axial stress and the bending stress on the bolt are measured by strain gages to verify the results from the analysis of the T-flange of various geometry. The obtained results are as follows : (1) A simple and useful method to analyze the stress in the bolt in the T-flange joint is proposed. (2) The analytical results show good agreement with the experimental results.
