represents the effective angle of internal friction of the soil.
Culvert walls and slabs often require shear reinforcement, particularly near the corners where shear forces are highest. If the concrete shear capacity ( VRd,ccap V sub cap R d comma c end-sub ) is insufficient, shear reinforcement ( VRd,scap V sub cap R d comma s end-sub ) must be provided. : Used for irreversible limit states
