b_w = web width or diameter of circular section, in.
d = distance from extreme compression fiber to centroid of longitudinal tension reinforcement, in.
d_b = nominal diameter of bar, wire, or prestressing strand, in
√f_c‘ = square root of specified compressive strength of concrete, psi
f_y = specified yield strength of nonprestressed reinforcement, psi
f_yt = specified yield strength of transverse reinforcement, psi
h = overall thickness, height, or depth of member, in.
h_sx = story height for story x, in.
h_w = height of entire wall from base to top, or clear height of wall segment or wall pier considered, in.
l_d = development length in tension of deformed bar, deformed wire, plain and deformed welded wire reinforcement, or pretensioned strand, in.
l_w = length of entire wall, or length of wall segment or wall pier considered in direction of shear force, in.
M_u = factored moment at section, in.-lb
s = center-to-center spacing of items, such as longitudinal reinforcement, transverse reinforcement, tendons, or anchors, in.
V_u = factored shear force at section, lb
ϕ = strength reduction factor
