【Abstract】 Studying the static and dynamic characteristics of a 500 kV double circuit intermediate tower consisted of steel tubes and angel steels is very necessary.Some conclusions are shown as follows: results show that ultimate load capacity of different parts of the tower is nearly the same,calculated by using finite element software ANSYS,modal analysis shows that designing on the changing slope of the tower should be paid more attention to.更多还原
