End connections of all beams and girders shall have a minimum nominal axial tensile strength equal to the required vertical shear strength for allowable stress design (ASD) or two-thirds of the required shear strength for load and resistance factor design (LRFD) but not less than 10 kips (45 kN). For the purpose of this section, the shear force and the axial tensile force need not be considered to act simultaneously.
Where beams, girders, open web joist and joist girders support a concrete
slab or concrete
slab on metal deck that is attached to the beam or girder with not less than 3
-inch-diameter (9.5 mm) headed shear studs, at a spacing of not more than 12 inches (305 mm) on center, averaged over the length of the member, or other attachment having equivalent shear strength
, and the slab contains continuous distributed reinforcement in each of two orthogonal
directions with an area not less than 0.0015 times the concrete
area, the nominal
axial tension strength
of the end connection shall be permitted to be taken as half the required vertical shear strength
for ASD or one-third of the required shear strength
for LRFD, but not less than 10 kips (45 kN).
