The basic check for bearing is that the bearing capacity of the leg of
the angle cleat per bolt (Pbs) must be greater than half the resultant
force on the outermost bolt (Fs /2).
P
bs
For bearing the following checks should be made:
• bearing capacity of bolt
• bearing capacity of the angle
Bearing capacity of bolt
The bearing capacity of a bolt is given by:
Pbb = dtppbb
where d is the nominal diameter of the bolt
pbb is the bearing strength of the bolt = 1000 N/mm 2
tp is the thickness of the angle cleat
= 160 kN
160 kN > 29.6 kN
The bearing capacity of the bolt is adequate.
Bearing capacity of the angle
The bearing capacity of the angle is given by the following
expression:
Pbs = kbs d tp pbs
