Cyclic Behavior of Reinforced Welded Flange Plate Moment Connections with Triangular stiffener Plates

Regarding the importance of seismic performance and also the problems of moment connections, representing an accurate and efficient scheme to reinforcing could be useful to eliminate these problems. Assuming that (CJP) welds between top flange plate and column face have poor quality or strengthened...
