Structural Analysis of Tension Tower Subjected to Exceptional Loads During Installation of Line Conductors

The paper presents results of study dealing with verification of the impact of different installation options (defined by the distance and tilt of anchoring cables from the tower axis and the distance and tilt of winch from the tower axis) to meet the limit state conditions for the tension tower subjected to exceptional loads during installation of overheads lines. 36 optional positions of anchor and winch have been considered. In current practice both the winch and the anchor are mounted at the distance from the axis of tower equal to 2 times H (where H - the distance above ground level on which an anchor or cable are fixed to the tower). It has been shown that the anchor as well as the winch can be fixed to the temporary foundations at the distance equal to H without any hazard to the safety of the structure.
