TEST METHOD ON TORQUE COEFFICIENT AND ANTISLIDE COEFFICIENT FOR HIGH STRENGTH CONNECTING BOLT

The torque coefficient and antislide coefficient is important evaluation parameter of the performance class of high strength bolt. The interference factors of torque coefficient were discussed,and the influence rule of main parameters were analyzed by theoretical and experimental method. It was explored that the quality control during the process of testing antislide coefficient of high-strength bolt faying surface of steel structures ,and some problems in the test were also solved.
