摘要	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. © Maxwell Scientific Organization, 2012.
