| Zusammenfassung: | For several years, hybrid structures such as CFT and RCS have been studied and their good performance has been proved. By applying the benefits of concrete and steel together in hybrid systems, a connection with good performance is achieved. Composite structures have been widely used in the construction of buildings due to their excellent static and earthquake resistant properties, such as high strength, high ductility, and large energy dissipation capacity. In this paper, an experimental investigation of the perimeter diaphragm and internal plate effects on a hybrid connection of steel beam to concrete column has been conducted. So, a concrete connection and three composite connections were constructed and tested under cyclic loading. A concrete connection was the standard reference connection and the following three connections were proposed as composite connections of steel beam to concrete column: perimeter diaphragm and internal plates, perimeter diaphragm and inner shearheads, and post tensioned composite. In all these composite connections, the concrete column in the panel zone has been confined with a steel sheath. The perimeter diaphragm makes the plastic hinge form at a distance from the connection bay and column edge, and the connection elements remain in an elastic state. The results indicated that composing the connection created an increase in loading capacity and energy dissipation. An increase in the ductility of composite connections with th |
