Abstract:
The high-neck flanges used in steel tube structures which were from Liantang to Sijing 500 kV transmission line in the power transmission towers were taken as the test objects. The static load test and finite element parametric analysis of 12 full-scale models of high-neck flange which included 4 different sizes were carried out. Based on the test and finite element parametric analysis results, the corresponding construction proposals were put forward. The result shows that the ultimate carrying capacity of the high-neck flange is above 1.6 times of the design load and has an adequate safety reserve. The thickness of flange plate and the height of flange neck carry greater impact on the flange bearing capacity, the overall stiffness is increased by increasing the thickness of flange plate and the height of flange neck, which will reduce the stress of flange neck and flange plate. The high-neck flange during the test process has a higher carrying capacity and clear signs before damaging. The high-neck flange has high safety reserve, and can be widely applied in engineering.
