Analytical Study on Side Plate Moment Connections AffectingCyclic Behavior

The common method of connecting I-beam to box column in the case of moment connections has a main problem, that is brittle fracture of full penetration groove welds of beam flanges to the column. To modify the connection, we have proposed a new detail. In the new geometry of connection, there is a gap between beam end and column face. The moment transfers from beam to the column by two full depth side plates. The tensile force is not directly applied to the column face. Therefore the problems of the brittle fracture of full penetration groove welds are completely eliminated. The finite element method was used for investigating the cyclic behavior of two-way moment connections with side plates. Results show that these connections have high strength and stiffness and cause the ductile behavior of structure with formation of plastic hinges in the beams
