Seismic Behavior and Design of Gusset Plates

This report presents information and tips on seismic behavior and design of gusset plates used in steel
concentrically braced frames. Gusset plates are used in steel building structures to connect the bracing
members to the beams or columns. Gusset plates are also used in connections of steel trusses. In this
report, first a summary of behavior of steel gusset plates is presented. This summary is based on the
information obtained from laboratory tests, investigation of performance during actual earthquakes and
analytical studies. After presenting the summary of behavior, a chapter is devoted to discussion of
provisions in the current design codes that are relevant to seismic design of gusset plates. Then, seismic
design of gusset plates is presented.
