You need to ask your supplier to ensure that you use the correct yield strength, as not all grades of steel are equal e.g. S275, S355, S420 etc where 275 is the yield strength in MPa or N/mm2

Nice script. You might get a bit more response on places like eng-tips if you want more feedback. I'd say the ability to add point loads would be nice, you probably don't see too many of those in residential properties though.

If you have an open section (e.g. I-beam, parallel flanged changed, equal angle i.e. with a closed flow of shear flows within the walls of a section) this formula will give you a good enough approximation: J = bt^3/3 where b is the always the longer side. e.g. for a rectanngle J = breadth *...

Just model the resistance as a pressure, it will have a favourable effect against the applied wind forces. Water should not be treated as a support, it has no shear strength unlike soils say which are typically modeled as springs

What you have is a mechanism (i.e. the number of degrees of freedom is less than the number of equations . As the only two supported sides are simply supported only (i.e. have no fixity). If the supports are truly supported and have no fixity the beam will simply be allowed to rotate at its free...

Thanks guys for the help! : )
