In this study, a new connection joint of cover-plate-haunch connection was brought forward on the
basis of improving haunch connection and cover plate connection. This kind of connection joint not only
overcomes the shortcomings that bilateral haunch connections affect the flatness of floor and the interior
appearance, but also strengthens the connection performance. ABAQUS finite element software is used to study
node stress, plastic zone distribution, ultimate bearing capacity and hysteretic behavior. The result of new
model is compared with past model. The results indicate that the new connection can effectively reduce stress
concentration on butt weld of the joint, make the plastic hinge away from the connection and lower the
possibility of brittle fracture. The ultimate bearing capacity of new connection can be increased 23% than
normal connection, equivalent viscous damping coefficient and ductility factor is respectively 0.321 and 4.06,
therefore the new connection is theoretically feasible and practical in application as well as excellent
performance in earthquakes and the ideal energy dissipation.
Key words: Cover-plate-haunch connection, ductility factor, energy dissipation, equivalent viscous damping coefficient, haunch connection, hysteretic behavior, plastic hinge
