Equation I8-1

The nominal shear strength of one steel headed stud anchor embedded in a solid concrete slab or in a composite slab with decking shall be determined as follows:

Qn=0.5AsafcEcRgRpAsaFuQ_{n}=0.5 A_{s a} \sqrt{f_{c}^{\prime} E_{c}} \leq R_{g} R_{p} A_{s a} F_{u}

where

  • Asa= cross-sectional area of steel headed stud anchor, in. 2( mm2)\begin{aligned} A_{s a} & =\text { cross-sectional area of steel headed stud anchor, in. }^{2}\left(\mathrm{~mm}^{2}\right)\end{aligned}
  • EcE_{c} = modulus of elasticity of concrete

wc1.5fcw_{c}^{1.5} \sqrt{f_{c}^{\prime}}, ksi (0.043wc1.5fc,MPa)\left(0.043 w_{c}^{1.5} \sqrt{f_{c}^{\prime}}, \mathrm{MPa}\right)

Formula 2

= 0.6 for steel headed stud anchors welded in a composite slab with deck oriented perpendicular to the beam and emid-ht <2e_{\text {mid-ht }}<2 in.

emid-ht <2e_{\text {mid-ht }}<2
