【 摘 要 】

A-shaped and steel tube structures have been widely applied when designing 500kV substation frame in China. While, compared with steel tube, angle steels have an advantage of easy-transporting, especially in oversea projects. However, researches on substation frame with angle steel were not enough. In order to find out the best root span of 500kV substation frame under similar engineering conditions, using the overseas project substation frame as an example, the substation frames with different root span have been detailed calculated, to find the best root span according to the cost of it. When the height of column is about 30m, the root suggestion value is 6.1m3.1m. And then, the buckling analysis of the overall structure has been carried out by ANSYS, to find out that the weak part of the structure is in the middle of it. The structural adjustment is carried out for the weak part, including adjusting the web members and the chord members, to obtain a higher bearing capacity of the structure.
