| Abstract: | Based on the basic principle of material mechanics, this paper analyzes the simplified model of frictional high-strength bolt for steel structure, and proposes an analytical formula for solving the stress concentration factor when considering the influence of the thread angle, and proposes a simplified formula by appropriately simplifying. In addition, the causes of stress concentration in frictional high-strength bolt are explained. Finally, by comparing the calculation results with the finite element results, the correctness of the analytical formula is proved, which has certain practical significance. |
