Keywords:transmission steel tower, snow cap

In transmission towers can be damaged by snow cap. Therefore, authors conducted full-scale tests to confirm the relationship between the change in member inclination and the snow load. Furthermore, we developed an analytical model to simulate the test results and investigated countermeasures against snow loads on the analytical model.
