Question

Consider a bolted plate of thickness 8 mm to a gusset plate of thickness 12 mm of plate. Block shear strength of plate in tension yield and shear rupture will be____ kN. (Use Fe410 grade of steel)

Answer 1

For tension yield and shear fracture,

$Strength=\frac{A_{tg}{f}_y}{{\gamma }_{m0}}+0.9\frac{A_{vn}{f}_u}{\sqrt{3}{\gamma }_{m1}}$


$A_{tg}=80\times 8=640m{m}^2$

$A_{vn}=\left[\right(4\times 40)-(4-\frac{1}{2})\times 16]\times 8=832m{m}^2$

$f_u=410MPa,f_y=250MPa$

$\therefore T=[\frac{640\times 250}{1.1}+\frac{0.9\times 832\times 410}{\sqrt{3}\times 1.25}]\times {10}^{-3}$

$=287.26kN$
