FE models incorporating pretension of fasteners, full contact interactions and nonlinear material and geometric characteristics of extended endplates are developed and validated against experimental results available in the literature. Moreover, eight models on extended endplate (four having circular bolt configuration, and four having rectangular bolt configuration) are tested under monotonic loading. A parametric study is conducted varying column flange thickness and bolt configuration (circular and rectangular) to investigate their effect on the induced prying forces, bolt force, and force total-deformation responses. Contributions from endplate deformation (inducing primary prying forces) and column flange deformation (inducing secondary prying forces) are quantified for both extended endplate connections with circular and rectangular bolt configurations. The results show that extended endplates with circular bolts configuration have more ductile behavior and exhibit lower secondary prying forces when compared to their counterparts with rectangular bolt configurations. This study sheds the light on the behavior and strength of eight bolted unstiffened extended endplate with circular bolt configuration. Future experimental research work will be conducted to collect data that will lead to the prequalification of this connection typology for use in moment resisting frames.
