Steel-steel tube confined concrete combined cable bent tower

The embodiment of the invention provides a steel-steel tube confined concrete combined cable bent tower which comprises a box body and a steel tube confined concrete column body, wherein the steel tube confined concrete column body is arranged in the box body, and the steel tube confined concrete column body is fixedly connected with the inner wall of the box body through a first web plate. According to steel-steel tube confined concrete combined cable bent tower provided by the embodiment of the invention, the confining effect of steel tubes of steel tube concrete on concrete is fully utilized, and the compressive bearing capacity of the cable bent tower is remarkably improved; meanwhile, an external box body mainly bears bending loads, and the wind resistance of an ultrahigh cable bent tower can be greatly improved; according to the stress characteristics of an ultra-high cable bent tower of an ultra-large-span suspension bridge, the material characteristics of the steel tube confined concrete column body a
