### DESIGN FOR SHEAR2008

DESIGN FOR SHEAR Max Shear due to loads V u ≤ Design Shear Capacity ϕV n Where ϕ 0 75 Design Shear Capacity ϕV n Design Shear strength of concrete ϕV c Design Shear strength of reinforcement ϕV s ϕV n ϕV c ϕV s Therefore V u ≤ ϕV c ϕV s Shear force that concrete can resist without web reinforcement V c ACI Eq 11 3 V c 2 √f
