This paper presents a three-dimensional Finite Element model for the analysis of bolted end-plate steel connections using a general purpose Finite Element Software ABAQUS. The proposed model takes into account material and geometrical nonlinearities, initial imperfection, contact between adjacent surfaces and the pretension force in the bolts. The numerical results by the proposed Finite Element model are calibrated with published experimental results ''briefly reviewed in this paper'' and verified that the numerical model can simulate and analyze the overall and detailed behavior of different types of bolted end-plate steel connections. Parametric study is then carried out to study the rotational behavior with variations in: bolt diameter, end-plate thickness, length of column stiffener, angle of rib stiffener. The results are examined with respect to the failure modes, the evolution of the resistance, the initial stiffness and the rotation capacity. The rotational behavior of the bolted end-plate steel connection is discussed in detail, and a recommendation for the design purpose is made.to discuss their dynamic behavior under two moving loads.
