Question

The length of bolts joint made from $16$ $mm$ bolts is $300$ $mm$. The reduction factor used for calculation of shear strength of bolts is

• A. 0.929
• B. 0.967
• C. 0.981
• D. No reduction factor for given data

Answer 1

The correct option is C 0.981

Length of joint, $l_j=300mm>15d(15\times 16=240mm)$
$\therefore$ Reduction factor, ${\beta }_{ij}<1.075-\frac{l_j}{200d}$
$=1.075-\frac{300}{200\times 16}=0.981$
