FIN PLATE CONNECTION<br />

Design code Made by DBM Sheet no.<br />

BS 5950 Checked by BD<br />

The basic requirement is that the moment capacity of the fin plate<br />

must be greater than the applied moment<br />

Mc ≥ Fva<br />

For low shear<br />

Fv £ 0.6Pv<br />

P v = 462 kN (from previous page)<br />

0.6P v = 277.2 kN<br />

110kN < 277.2kN<br />

\ Section is subject to low shear<br />

Mc = [ 2¥ 40+ ( 4-1) ¥ 80] / 10 kNm<br />

= 46. 9 kNm<br />

110 ¥ 50<br />

Fva = kNm<br />

= 55 . kNm<br />

46.9 kNm > 5.5 kNm<br />

Therefore the fin plate is adequate in bending.<br />
