Hi all. I have a question about Reinf crack for prestressed concrete as follows: If you calculator stress bot of section beam in MinMz_Service exceeding allowable stress tension limit is 0,5 x sqrt(f'c), you can calculator reinf area to control crack…

Our firm noticed, during the design of a hollow box bridge with inclined top slab (curved bridge with 7% transversal slope), that elastic stress calculation performed by RM bridge is not correct. In fact, even if it's possible to model generic cross sections…
