In order to study internal force distribution and failure mode of key parts of high-voltage transmission tower under the action of ultimate load, the micro scale model for the key parts of the tower and the macro scale model for other members are established by the finite element software ABAQUS. And a uniform multi-scale numerical model is established by coupling two scale numerical models. Then apply the limit load on the multi-scale model under the extreme climate condition, and the failure mechanism and failure mode of the transmission tower is obtained under the limit load.
