Design force component in each bolt parallel to the grain is less than the permitted design force per bolt; therefore OK

10. Shear strength of the timber

The design shear force on the timber:

Summation of 'x ' distances of the bolts in the shear zone, Sx

Maximum shear force - based on the forces in two shear planes in the line of bolts to the extreme left of the connection, F 1v d: (equation (12.18))

The design shear force at the end of the beam due to vertical loading:

Design shear stress within the connection area, Tc.s:

Shear stress in the beam at the connection, Tb.s:

Design shear strength, fv.d
