Prestressing Application Method of Guyed Wind Tower with Ice-coated Cable
The guyed wind measuring tower was a high-rise structure composed of an upright truss structure and several layers of steel strands arranged diagonally along the height direction.The proportion of structural failure occurring under normal design and construction was high in civil construction.Many of them,there were some structural failures caused by the combined action of wind load and ice load.Nowadays,the analysis of the overall stability of the wind tower under the combined action of ice loads and wind loads in China was not mature.,so it was necessary to carry out the follow research.ANSYS finite element software was used to establish the guyed wind tower model,according to the code to impose the wind load and the ice load,by changing the intensity of the prestress of the steel strand,we observed the displacement of the tow-er node,summarized the rule of the cable wind tower displacement under the condition of ice covered,and finally determined the most reasonable method of prestress of the steel strand.
