Ever since I purchased the 3D printer I wanted to do castellated beams. A castellated beam is a beam style where an I-beam is subjected to a longitudinal cut along its web following a specific pattern in order to divide it, and reassemble the beam with a deeper web by taking advantage of the cutting pattern.
What I have done before the printer was drill HOLES in Girders to capture the idea of a castellated beam. So here I am needing a two 7" track support beams to support track in the middle of a lake. The track is straight for about six inches then curves off on a 072" curve.
Using Rhino 5, in the top view, I created the straight beam section and then copied the straight beam. Using the "Bend" command in Rhino I created a spine to carry out my curvature and bent the straight beam.
Here it is in prospective view. Note the side beams that are castellated; note too the weld line, yes I added a weld line.
the support columns are curing now. as I said the bridge is in the middle of a lake.
The bridge has a railing as well,the support rails attach to the girders upper flange. the rail support was angled as well to come out on a 30 degree angle and midway the Bend command was used to straighten the supports vertical.
