Design force capacity per bolt per shear F 1h = nef ■ — plane parallel to the grain taking bolt nb spacing effect into account, F1h:

kmod.short

KM.connection

Design force component per bolt per FH,a = shear plane parallel to the grain in each of the bolts in the row, FH,a

Actual design force component in each bolt parallel to the grain is less than the design capacity per bolt per shear plane; therefore OK

10. Shear strength of the timber

The design shear force on the timber:

Summation of 'x' distances of bolts in Sx = 3 ■ x shear zone, Sx

Maximum design shear force - based on the forces in two shear planes in the line of bolts to the extreme left of the connection, F1V, vd: (equation (12.18))
