Abstract:

For the safety and stability of the 500 kV transmission line, SSZT1 angle tower which is widely used in the transmission project has been chosen for the prototype model test. In No.7 and No.18 load cases, bending occurs showing force differences between the real structure and the computational model. Aiming at the problems, the reasons for bending and solutions are introduced which could also be used as references for other tower design and tests.
