Design concrete bridge slab for tension and bending
Design concrete bridge slab for tension and bending
(OP)
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 (cl 5.7.6) and check that (M/Mr)+(P/Pr) < 1.
Any hints much appreciated.

This would be similar to analyzing a column, except you have tension instead of compression. The interaction chart and procedure is the same, though.
If you don't feel like creating an interaction diagram, PCAColumn does it rather quickly.
