In the aspect of structural connection, the main material of steel pipe tower is connected by flange or through connection, the inclined material and main material are connected by inserting plate or through connection, the main material of angle steel tower is connected by internal and external, and other members are connected by connecting plate and bolt. The flange and gusset plate connection structure of steel tube tower is relatively simple. Although the welding workload is increased, the adverse impact of eccentricity of angle steel members on the structural bearing capacity is reduced, and the stiffness and compactness of the connection joints are enhanced, which is helpful to improve the overall stiffness and stability of the structure and the ability to resist wind-induced dynamic load.
