Can you please clarify how the phiVn/Vu ratio is calculated? When I had calculate this using the values provided in my output, it does not match the value shown. For example, in the output below, at 0.5L, phiVn/Vu = 1.216; however, calculating phiVn = 0.9*(Vc+Vs.reqd) = 0.9*(40.216kip + 15.388kip) = 50.04kip, and Vu = 51.663kip, therefore phiVn/Vu = 50.04kip/51.633kip = 0.98 - where Vc is the shear strength provided by the Concrete, and Vs.reqd is the shear strength provided by the stirrups (according to the variable definitions). I am trying to do a quick check on the shear load ratings using these values, and they are not matching.
