Compared with the common angle steel tower, the narrow base steel pipe tower has the advantages of simple structure, beautiful appearance, small floor area and better coordination with the urban environment. In the construction of urban high pressure transmission line, the narrow base tower has its own unique advantages and wide application prospects. It has the advantages of ordinary iron tower processing, transportation, assembly, cost saving, small occupancy of single column steel pipe rod, small line corridor and beautiful beauty. In the optimization design of the narrow tower, how to take the wind vibration coefficient of the tower, how to consider the bending moment of the rod end, the design of the narrow base tower and the structure optimization of the narrow tower tower are all the problems to be solved urgently. In this paper, the modal analysis of a single tower is carried out to determine its vibration mode, and then the wind vibration coefficient of a narrow tower is analyzed. Finally, the influence of x and y direction vibration on the frequency of the tower is obtained.
