Abstract
Abstract In order to study the influence of restraint stiffness of main material on the compression stability bearing capacity of cross-bracing in transmission tower, in this paper, the load of cross-bracing under eccentric compression in transmission tower is simulated. The load test of 45 Q355 equilateral angle steel cross-bracing specimens with typical sections is completed, and an effective ANSYS finite element model is established for analysis. The effects of the restraint stiffness of main materials, slenderness ratio, material strength and the number of connecting bolts on the bearing capacity of cross-bracing are discussed, and the relevant laws are obtained, which provides a reference for engineering application.
