| As the important station in the power transmission, in the power transmission, the investment of towers is about 40 percent of the whole investment. The safety and dependability of the power transmission tower count for much with the safety and economy of the power system. The tower's losing stability under the wind force and earthquake force is the main reason in the tower's collapse incident. So base of the tower's static stability, holding the dynamic respond under the wind force and earthquake force is very important. At the process of building high tension tower, the aerosol-like holding poles have already been known as the chief appliance, the poles are influenced by wind force chiefly.Based on the finite element software ANSYS, five different cross-section aerosol-like holding poles are analysised under wind load and lifting heavy objects function in the paper, and obtain main member axial strength stress and diagonal member axial strength stress. While the paper derives the regression linear equation for the strength stress of the diagonal members by means of the regression analysis, demonstrate the safety and reliability of selection of the diagonal members. Aerosol-like holding poles are analysised for wind-induced vibration response, check the difference of poles'response between having wind fluttering factor and having no.At the process of building high tension tower, based on static analysis, the tower on the impact of holding pole will be got in the paper. Based on modal analysis , the basic vibration mode and frequency are got, then going on spectrum analysis and transient analysis acting at seismic waves of Taft and El-Centro. Comparing the results of transient analysis with Spectrum Analysis, besides the method in analyzing the seismic response of tower structure under the horizontal and vertical earthquake function are discussed. While the effects of vertical earthquake action on the tower structural horizontal and vertical performances are studied. |
