How does load transfer take place in telecom towers?
Both, the wind and the dead loads act on a telecom tower. How does the load transfer take place from superstructure to the foundation?
If it is a truss structure, it is transferred from the diagonal elements to the vertical elements and via tension to the bottom with compression added on the downwind side and tension added on the upwind.
If it cable stayed the truss of the tower is primarily for stiffness and taking the weight (dead load) straight down in compression while the guy cables take the tension of the wind force, which also transfers some force to the truss.
If it is a tubular structure, then all the forces are taken in the skin and transferred down with compression added to the dead load on the down wind side and tension subtracted on the up wind side.

Through the connecting bolts that hold it to the foundation.

The height of tower is one of the factor to determine the range of transmitter. The size of tower depends on the size of antenna and the shape of antenna which can be affected by the wind blowing factor.
