I am to provide the foundation design to a 60 foot communications tower. This is not a tower I have been involved in the design of and know little other than it is 60 feet tall, 3 2 1/2" dia pipe legs, and angle braces. Each side is 24" forming a triangle. Pretty standard stuff near as I can tell. Without redesigning the entire structure is there a way to obtain the base moment of the tower? All I am looking for is the Base Moment as the force to each leg could be obtained from the base moment. I do not have a manufacture or any design documents for the tower itself. Any Suggestions?
