STUDY ON SEISMIC BEHAVIOR OF STEEL BEAM-TO-COLUMN PANEL ZONES
Beam-to-column panel zone behavior in a steel moment-frame is characterized by the surrounding acting
forces and its rotating deformation. When subjected to lateral forces, panel zones are deformed in a
parallelogram pattern that one side of its diagonal direction is in tension whereas the other side is in
compression. Moreover, right angles at the joints between the beam, column ends and the panel remains right
angles. Shear strain causes the panel to rotate at a finite angle characterizing its rotating deformation. Based
on experimental results from a full scale steel building collapse test, this paper discusses the elastic and
elasto-plastic behavior of some typical panel zones.
