Formulas: Shear Strength of End Web Panels with $a / h \leq 3$ Considering Tension Field Action

Formula 1

a / h \leq 3

V_{n}=0.6 F_{y w} A_{w}\left|C_{v 2}+\beta_{v} \frac{1-C_{v 2}}{1.15 \sqrt{1+(a / h)^{2}}}\right|

\beta_{v}=\frac{2.8\left(\sqrt{M_{p f}+M_{p m}}+\sqrt{M_{p s t}+M_{p m}}\right)}{h \sqrt{F_{y w t_{w}}\left(1-C_{v 2}\right)}} \leq 1.0

(i) When $C_{v 2} \leq 0.8$

C_{v 2} \leq 0.8

d_{e}=35 t_{w}\left(0.8-C_{v 2}\right)^{2}

(ii) When $C_{v 2}>0.8$

C_{v 2}>0.8
