many thanks.I downloaded the trial version of PCA but what is the code related to the AAshto LRFD? I can choose ACI 318-05, ACI 318-02, CSA A23.3-04, and CSA A23.3-94. Can I use also PCA slab? Does it do also crack analysis?
it's not a bow string arch bridge, it comprise 3 steel arches with the concrete slab on top, the slab is not prestressed and for its particular shape the deck is in tension, any hints for design the slab with tension and bending?
the slab is in a top of an arch thus it behave like a tie, bending is coming from the live loads. The slab thickness is 325mm, concrete 50MPa, rc steel 420MPa, cover 50mm and factored forces P=1980KN/m, M=293KNm/m, apologies for the SI units but the bridge is in the Emirates and they using SI.

Hello all, I have to design a reinforced concrete slab using the Aashto, what is the correct approach to design the reinforcement in the slab to take into account both tension and bending?
I was thinking find the flexural resistance Mr=0.9*Mn (cl 5.7.3.2) then the tension resistance Pr=0.9*Pn...
