An analytical method is developed for predicting the ultimate strength of eccentrically loaded fillet weld connections not free to deform in the compression zone. The method uses the true load-deformation response of the welds rather than some idealized one. The validity of the approach has been verified by a testing program using 16 full-size specimens. Comparison of the ultimate strength obtained by this method with allowable loads calculated assuming elastic behavior shows that the resulting factor of safety is both high and inconsistent.
