| Abstract: | According to the force transmission characteristic of friction-type connection for the high-strength bolt,we analyzed the necessary conditions for the equal-strength connection of the whole section,and proposed the equal-strength coefficient for the friction-type connection node of high-strength bolt and the calculation method for the coefficient,and put forward the design principle that the net section coefficient should not be greater than the equal-strength coefficient to ensure the structural safety of the large-span truss in port engineering. |

| Keywords: | equal-strength connection equal-strength coefficient large round hole net section coefficient |
