eiffel tower is a frame structure.
its a frame
the Eiffel tower is a definite frame. if the tower had something over the frame it would be a mass so the Eiffel tower would never be a shell if it had the framing still inside of it.
The observation platform/restraunt at the top would be a frame structure. The concrete middle would be a shell structure because of the elevators running through it. The base would be a mass structure, no question why there. So i guess it's a mixture of all 3 structure types!! U
