Strengthening of Composite Beam-to-Column Joints: Static and Seismic Behavior

Loho, G. / Lachal, A. / Aribert, J. M.

This paper deals with the strengthening of beam-to-column end-plate bolted joints. Two strengthening dispositions have been developed and studied. The first one consists in adding a haunch welded on the beam bottom flange in the vicinity of the column. The second one consists in strengthening the column web panel (in presence or not of haunches) with double steel plates. This strengthening arrangement is studied in this paper from both experimental and numerical approaches. Based on these studies, two new static design models are proposed. The first model deals with the composite haunched joints. The second model provides a design method for the column panel zone strengthened by double steel plates.
