Although different methods of design of beam to column rigid connections are introduced in codes of practice, yet these methods are not accurate specially in calculating bolt force and end plate capacity. A brief review of previous studies in the field of flushed bolted rigid connections is introduced. A nonlinear finite element model accounting for both geometric and material nonlinearities is presented. Four full scale specimens for flushed rigid connections were prepared to verify the numerical model. The material properties of the steel plates and bolts were investigated. A parametric study is carried out using the verified model for different flushed connections with one and two bolt rows in tension side. Interaction curves for the studied connection configurations have been presented. The effects of the different investigated parameters on the forces, prying forces and moment capacity of the connections as well as their modes of failure have been discussed. A comparative study between the finite element results and those obtained by adopting the AISC guide No. 16 is performed and design charts for the connections are also plotted. Equations to calculate the moment capacity of the flushed connections have been proposed using regression analyses. A comparison between connection moment capacities calculated using the proposed equations and those calculated using the finite element model has been carried out revealing good agreement between them.
