Reinforcement yield strength
(OP)
what is the effect of having two different yield strengths of bars in the same concrete section , what to do when designing the section ... if the smallest yield strenth to be considered, what about the elastic modulus






RE: Reinforcement yield strength
Just use the summation of FyAs for the different bars and use that value as your tension force in the design/analysis equations.

The difference with the PT steel is that it is initially stressed to about 180-200ksi so there is still only about 50 - 70ksi increase available, and that is to fracture.
Everything said above is true as long as the modulus of the reinforcement and the ductility of the reinforcement is similar!
