Abstract

The aim of this study is to present a new and suitable connection for I-shaped beams and box columns that is both constructionally convenient to implement and reliable in terms of its performance. Six full-scale experimental samples were constructed and subjected to cyclic Quasi-static loading. The first sample included an I-shaped beam which was directly connected to a box column, the second sample incorporated a channel link, and stiffened channel links were used in the remaining four samples. The results show that compared to the direct connection, using the stiffened channel link significantly improves the performance of the connection and increases its ultimate strength and ductility by 58% and 70%, respectively. Also, these connections satisfy the code-specified criteria for special moment resisting frames. They are therefore a suitable detail for rigid I-shaped-beam-to-box-column connections in seismically active regions.
