I have designed many railings of this style utilizing a 3D frame analysis program. Designing one post like a flag pole is asking for problems. The entire railing should be considered a unit. Keep the posts 5'-0"+/- c/c. If there is a 4" high toe guard, use it in the anchoring design...
I've been searching for a Software Program that will analyse/design using Alum. Sections e.g. Tubing, pipes, extruded shapes, needed to design Guard Railings, catwalk, mezzanines etc. Eagle Point I have been using is "old technology" Any ideas greatly appreciated.
