Eccentrically Loaded Bolted Connections

Although present methods of investigating eccentrically loaded fastener groups have produced safe designs, the factor of safety is, in general, unknown. A rational theoretical method of predicting the ultimate load on eccentrically loaded fastener groups is developed. The method is based on a recognition of the true load-deformation response of the fasteners. The validity of the theoretical approach has been verified by a testing program using eight full-size specimens. The test results agreed favorably with the theoretical predictions. By making use of the more accurate predictions presented, the factor of safety can be brought in line with that of other structural components and can be established at a constant value for all connections of this type.
