Take your 3000 degree propane torch (LOL) and try to make a 60 foot steel girder into a 60 foot 6 inch girder... i'll wait!  |
this is the second time you've made gross exaggerations to the fact that metal expands, the first being the car engine.
Metal doesn't need to expand that much nor does any material need to in order to make it deviate from the tolerences it was designed for. Most of the times when it falls out of tolerance, it fails.
Steel bridges grow and shrink by inches but were designed to adjust to the loads and they do grow by inches in some cases, that's why there are gaps in them at specific locations. Again, it's about engineering the loads and tolerances in such a way that the object will do what it was designed to do.
Applying direct heat to ONE location does not create the same conditions that allow for bridge steel to grow and contract.
I have to agree with Dilbert that you may appear to know the practical methods for using the materials but not how the materials truly react to loads and conditions.
