| Abstract | ||||
| This article discusses the results of seven (7) fastener joints analyzed using the enhanced analysis approach proposed in Reference 2 as compared to the results of finite element models that were constructed to simulate the actual properties and behavior of these joints. These finite element models, unlike the idealized ones of Reference 2, permit flexural and shear deformations in the joint plates. Results of the proposed enhanced analysis approach differ significantly from the results of the realistic FEM models. The difference is approximately between +20% and -80%. Results of the realistic FEM models also indicate that the moment induced tensile load is carried mainly by the fasteners at the fitting’s free edges being pulled up by the out-of-plane bending moment. A probability distribution of fastener maximum load correction factors is established for use with the proposed enhanced analysis approach. | ||||
