Composite Truss 1

[slickdeals]

Guys,
Have anyone of you modeled a composite truss where the top chord is composite? Do you have any suggestions on how to model it in say ETABS or SAP?

The truss is 100' long and carries a roof top garden about 300 psf SDL.

Thanks

There are a couple of comapanies (Florida I think) that do this with bar joists. They build a prefabbed floor system
with bar joists - upside down - then pour in say 4'' of concrete which encases the top chords of the joists. Let it harden and ship to the site.

Sorry - cannot remember the names.. maybe Google??

I know Vulcraft has composite joists
