I'm inputing data into a SolidWorks material profile, but i'm having difficulty determining the value of the elastic modulus(adsbygoogle = window.adsbygoogle || []).push({}); of steel reinforced concrete(psi)

i'm looking at the following source for material properties:

http://www.fhwa.dot.gov/pavement/pccp/pubs/05081/chapt3.cfm [for elastic modulus of concrete and steel rebar]

Here it gives young's modulus of concrete and the value for the rebar.

"Young's modulus of concrete at 28 d, Ec,28 (GPa (x 106 lbf/in2)) 33.10 (4.80)1 and 34.48 (5.0)2

Young's modulus of steel rebar (GPa (x 106 lbf/in2)) 200.00 (29.00)"

I'm confused because steel reinforced concrete combines both steel and concrete, which value or at what proportions do I use? Of course the whole point of adding steel is to make the concrete less elastic, so obviously I cant use concrete, but I obviously cant use just steel either. See my dilemma?

Also I don't understand how to obtain psi from "(GPa (x 106 lbf/in2)) 33.10 (4.80)1 and 34.48 (5.0)2" either.

Thanks for your help,
