Composite Beam Design
Composite Beam Design
(OP)
Good Afternoon everyone:
Whats the quickest way to design composite steel beams? I am doing hand calculations and it is taking a while to do just one. Is there a free software anywhere to experdite this process? Any help would be appreciated.
Thank You

I've also seen a composite beam design module in Enercalc but my personal preference is RAMSBeam.

The effective slab thickness is the lesser of .25*span, 16*the slab thickness + width of the beam, and 1/2 the span to the adjacent beam for beams with slabs on both sides.
There are also requirements for slab and deck and steel studs often requiring that the composite deck be used in an inverted manner to achieve sufficient concrete for studs.
As far as the point loads, there are requirements for distributing the shear connectors along the beam to roughly correspond to the shear force diagram. It is possible, for example, to have a composite beam with a single large point load, say, at third span.

Why would the manner of determining the slab with for the girder be less than that for the purlins as long as the shear can be transferred to the slab either through the stud or through the slab? There is also a requirement for providing trnasverse rfg. CSA requires 0.5% of the effective concrete area and the deck ribs provide stability. Consider it is a steel beam with a concrete T beam secured to the top where the stem of the T is only a matter of a few inches high. If this doesn't explain it, I may be missing your question completely...

For the most part the composite design mimics a limit states approach and is fairly straight forward. I used to have programs for the old TI-59 (I think that's the model) as well as the old HP??. I've not had the need to write one for the TI-89 that I currently use...

Even one beam design can take longer than a few hours by hand. I have no affiliation with RAM International but for me, RAMSBeam is the best program for simple composite beam design.

Also available in the UK is free software from cellular beam fabricators (Westok and Fabsec) which can do composite design of cellular beams with and without openings in the web. I dont think these have US design code options.
Do the equivalent US companies not provide similar free software?
