d is the nominal diameter of the bolt<br />

pbb is the bearing strength of the bolt = 1000 N/mm 2<br />

tp is the web thickness Table 31<br />

\ Pbb = 20 ¥ 6.9 ¥ 1000/103 kN<br />

= 138 kN<br />

138 kN > 59.2 kN<br />

The bearing capacity of the bolt is adequate.<br />

Bearing capacity of web<br />

The bearing capacity of the web is given by the following expression:<br />

but<br />

Pbs = kbs d tp pbs<br />

Pbs £ 0.5 kbs e tp pbs<br />

where e is the end distance in the direction of bearing and is conservatively<br />

taken as the horizontal end distance<br />

pbs is the bearing strength of the web = 460 N/mm 2 for S275<br />

steel<br />

kbs is the coefficient allowing for the type of hole = 1.0<br />
