DEAR GURUS,
Can somebody help? I am faced with the design of a 140m high guyed tower. What are the forces one has to consider in the design of the guy wires, the main legs, the horizontal and diagonal members of the angle steel sections?
The tower is square in plan and the guy wires (at the four corners) at 4 levels; 30m, 60m, 90m and 120m plus a 20m free end.
I have calculated the surface areas of all the antennae and the steel members. Is it just the matter of finding the component of the wind forces in the various wires and dividing by the strengths of the cables?
No moment at the base. Is foundation designed with only the axial load? We handle normally self supporting towers but do not have sufficient experience in handling guyed towers.
