Is beam-mesh better than solid-mesh when doing structural simulation?

Beam meshes are much more computationally efficient. But they make many more assumptions. For most systems, you beam mesh will solve orders of magnitude faster, making it possible to solve certain systems that would be out of the question with solids (a broadcast tower leaps to mind). But beams are essentially automated hands calculations using (I think) Timoshenko beams.
