摘要：
The static performance of transmission line span tower space steel network structure is relatively well studied, but the dynamic performance research lags behind, which has become an important factor limiting its general promotion. In this paper, a combination of numerical and analytical methods is used to carry out a modal analysis of the spatial steel network structure of transmission line towers. The vibration patterns and self-oscillation frequencies of two types of tower structures, spanning towers and ordinary towers, are analysed. The dynamic characteristics of the spatial steel mesh structure of the spanning tower are obtained, laying the foundation for the subsequent analysis of the dynamic performance of the transmission line spanning tower.
