Equation I4-2

The nominal shear strength, VnV_{n}, shall account for the contributions of the structural steel section and concrete infill as follows:

Vn=Ks+Ksc2AswFyV_{n}=\frac{K_{s}+K_{s c}}{\sqrt{2}} A_{\mathrm{sw}} F_{y}

where

Asw= area of steel plates in the direction of in-plane shear, in. 2( mm2)A_{s w}=\text { area of steel plates in the direction of in-plane shear, in. }^{2}\left(\mathrm{~mm}^{2}\right)

Equation I4-3

Ks=GsAswK_{s}=G_{s} A_{s w}

Formula 3

Gs= shear modulus of steel =11,200ksi(77200MPa)Ksc=0.7(EcAc)(EsAsw)4EsAsw+EcAc\begin{aligned} G_{s} & =\text { shear modulus of steel } \\ & =11,200 \mathrm{ksi}(77200 \mathrm{MPa}) \\ K_{s c} & =\frac{0.7\left(E_{c} A_{c}\right)\left(E_{s} A_{s w}\right)}{4 E_{s} A_{s w}+E_{c} A_{c}}\end{aligned}

Formula 4

Ksc=0.7(EcAc)(EsAsw)4EsAsw+EcAcK_{s c}=\frac{0.7\left(E_{c} A_{c}\right)\left(E_{s} A_{s w}\right)}{4 E_{s} A_{s w}+E_{c} A_{c}}
