Anti-fatigue pre-stress steel pipe column structure
The invention discloses an anti-fatigue pre-stress steel pipe column structure which comprises multiple sections of steel pipe columns, wherein all the sections of steel pipe columns are connected by flanges to constitute a tower pillar, and pre-stress cables are disposed inside the steel pipe columns from the tower pillar foot to the tower pillar top and respectively anchored on a lower end plate structure and an upper end plate which are located on the pillar foot and the pillar top. Under normal working conditions, as driven by wind loads and mechanical operation, pull force generated in the steel pipe column on one side of the tower pillar is smaller than pre-pull force applied inside the steel pipe column and the steel pipe pillar always keeps a stressed state, so that fatigue damages to the steel pipe column are avoided.
