An alternative to post-tension?

[jar546]

This does have an ICC-ES report and it looks rather interesting. I don't know about testing for seismic areas. Your thoughts?

DELTABEAM® is a superior composite beam enabling slim-floors for multi-story buildings of any type, whether low-rise or high-rise. Its composite action between steel and concrete allows for creative structures with large open spaces.

Underwriter laboratories (UL) fire tests have proven DELTABEAM® has excellent fire resistance without any additional protection. Its shallow design decreases a building’s floor-to-floor height while eliminating conflicts with HVAC systems.

Doesn't appear to be approved for California yet and requires more colums given 27" span limit,
Parking structures vs hotel uses or not?
Might bounce a lot.

given 27" span limit,

I didnt see that. Seems awfully short. I did see a comment on thd opening page that it can span 30 ft.

 

[ADAguy]

depends on thickness of beams.

ADAguy ... re-read what you typed. 27 inch span. Thats the same as a 5/4 deck board.

 

[ADAguy]

No no! 27' span!

50 PSF LL seems a bit light to support furniture and moving traffic as in humans and cars.

50 PSF LL seems a bit light to support furniture and moving traffic as in humans and cars.

Check out IBC T1607.1... 50psf is the specified LL for offices.

Definitely not intended for a garage application (i.e. supporting cars).

Offices also have a 15 PSF partition load on top of the 50 PSF live load (IBC 1607.5).
