Dynamic Characteristics Analysis of Two Adjacent Transmission Towers

Dynamic analysis models of two adjacent transmission towers, two adjacent corner towers and the correspond single-tower are established, its dynamic characteristics are analyzed and compared. The results showed that: Dynamic characteristics of two adjacent transmission towers are close, but the towers connected with the corner tower changes much. Compared with the single-tower, its dynamic characteristics have changed regardless of corner tower or straight line transmission towers. It is also shown that suspended cables not only have mass effects, but have coupled stiffness effects applied to towers on transverse direction and longitudinal direction.
