WEB CLEAT CONNECTION<br />

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

BS 5950 Checked by BD<br />

The connection is between a 356 ¥ 171 ¥ 45 UB (S275) beam and a<br />

254 ¥ 254 ¥ 73 UC (S275) column.<br />

The end reaction of the simply supported beam due to factored loads<br />

is 185 kN.<br />

Refer to Table 26.3 for design checks.<br />

Check 2 – Shear capacity of bolt group connecting cleats to web of<br />

supported beam<br />

Basic check is:<br />

Ps ≥ Fs/2<br />

The resulting shear force on the outermost bolt due to direct shear and moment<br />

is given by the following expression:<br />

F = ( F + F )<br />

2 2 1/ 2<br />

s sv sm<br />

where Fsv is the force on the bolt due to direct shear<br />

Fsm is the force on the outermost bolt due to moment<br />
