How do you calculate bolt bearing stress?

However, the average stress can be calculated as the applied force divided by the projected area of contact . Average bearing stress fp = P /( / ( db t), where P is the force applied to the fastener.

What is bearing stress formula?

To calculate bearing stress, divide the force over the contact area between the fastener and hole. Theoretically, it is often the simple area of the bearing surface. δb=P/Ab.

What is the minimum pitch distance of bolted connection?

6. What is the minimum pitch distance? Explanation: Pitch is centre to centre spacing of bolts in a row, measured along direction of load. Distance between centre to centre of fasteners shall not be more than 2.5 times nominal diameter of fasteners.

When do bearing stresses occur in single bolt connections?

This stress situation occurs also in friction-type joints when the frictional resistance is exceeded and major slip between the connected elements occurs. The paper focuses on the bearing stresses in single bolt connections. Such connections with bolt in bearing present a basic connection component of a multi-bolt connection.

What is the lug yield bearing stress ( Bry )?

The lug yield bearing stress (F bry.L) is (9-2a) (9-2b) The allowable lug ultimate bearing load (P bru.L) for lug failure in bearing, shear-out, or hoop tension is

How is the bearing strength of a lug determined?

The bearing strength of a lug loaded in tension, as shown in Figure 9-1, depends largely on the interaction between bearing, shear-out, and hoop-tension stresses in the part of the lug ahead of the pin. The net-section of the lug through the pin must be checked against net-tension failure.

What is the allowable bearing yield stress for bushings?

L The allowable bearing yield stress for bushings ( F bry.B) is restricted to the compressive yield stress ( F cy.B) of the bushing material, unless higher values are substantiated by tests. The allowable bearing ultimate stress for bushings ( F bru.B) is
