Asa = Cross-sectional area of shear stud, in.2 (mm2)
Ec = Modulus of elasticity of Concrete, ksi (MPa)
Fu = Specified minimum tensile strength of a shear stud, ksi (MPa)
As = Area of steel cross-section, in.2 (mm2)
d3 = Distance from the resultant steel tension force for full section tension yield to the top of the steel, in.
ILB ILB= Lower bound moment of inertia, in.4 (mm4)
Is = Moment of inertia for the structural steel section, in.4 (mm4)
ΣQn = Sum of the nominal strengths of shear studs between the point of the maximum positive moment and the point of zero moments to either side, kips (kN)
Ac = Area of concrete slab within effective width, in.2 (mm2)
Fy = Specified minimum yield stress of steel, ksi (MPa)
fc′ =Specified compressive strength of concrete, ksi (MPa)
d1 = Distance from the centroid of the compression force C in the concrete to the top of the steel section, in. (mm)
d2 = Distance from the centroid of the compression force in the steel section to the top of the steel section, in. (mm). For the case of no compression in the steel section, d2 = 0.
