comparision of 3 leg pipe tower or 4 leg angle tower

In fact installation cost, installation time take a large part of the whole cost. Only considering the material angle 4 leg tower typically requires 20 25% more steel than a comparable 3 leg pipe tower. This is partially due to the greater strength of pipe steel versus angle steel in

Communication Angle Steel Tower Communication tower

In addition, the angle coefficient of the angle steel is larger, and the auxiliary member without force increases the windage area of the tower, resulting in a much larger wind bending moment than the steel pipe tower, and the amount of steel used and the basic construction cost are also relatively large.

Experimental and numerical analysis of a bolted connection

In the prototype design, S355 grade steel (F y = 355 MPa) was used for the angle sections, and 20 mm diameter grade 8.8 bolts (F y = 640 MPa, F y = 800 MPa) were used for the connections. Each main leg in the prototype tower has two L150x16 angle sections positioned corner to corner below the investigated connection, while a single L160x17 angle section is used above this connection.
