Finite element modeling is employed to study the behavior and characteristics of flush end plate, bolted connections. To investigate the failure mechanism and non-linear behavior of the connections a 3D model is created and analyzed using non-linear material models and contacts between components of the connection. The paper shows the good agreement between the experimental and numerical results.

One of the most usual choices for the connection between the different structural members in steel structures is the bolted connection. The later provide a high level of deformation capacity for the whole structure and a level of stiffness comparable to that of fully welded connections. Top and seated angle with double web angle bolted connections are primarily used for beam-to-column joints. The most important factor for the structural response of beam-tocolumn connections is the rotational stiffness because it affects the behavior of the overall structural steel frame. For this purpose, many experimental tests have been recently conducted to obtain moment-rotation curves. Considering the moment-rotation curves obtained from experimental tests, a simplified analytical model has been suggested to predict the behavior of the connection by fitting techniques. The aim of the present paper is, from one side, the development of a moment-rotation curve for bolted top and seat angle connection with double web angle by means of a proposed theoretical model whose validity checked by comparison with experimental data, and from the other side, the determination of the appearing prying forces in the bolts by means of a simplified and reliable model.

According to the different designs of steel frames the connections can be characterized by different elastic, plastic and ductile behaviors. The most well-known connection type is the end-plate, bolted connection when a beam connected to the strong axis of a column. The design and analysis of this type of connection is discussed in detail in the EC3 Standard (1.8). On the other hand in the case of steel frames it is a common solution to connect a beam to the weak axis of a column or 3D connections and unfortunately current design standards do not contain solutions for these cases.During the current research project the elastic, plastic and ductile behaviour of beams connected to the strong and weak axis of columns have been investigated. The experimental program have investigated three connections: Type A is a connection without column web stiffeners, Type B is a connection with column web stiffeners and Type C is a connection using U beams to connect beams to the column.
