Study of inter story drift demands of multi-story frames with RBS connection

Amin Ghaznavi Osgoei, Mohsen Gerami


RBS connections are one of the most common deformable connections in the world. The plastic hinge will be placed in a conducted mode at a specific area in the beam using this type of connection. It is worth to mention that reducing the sectional area of the beam flange, in general, will cause a reduction in the strength and lateral stiffness of the structure. Hence, the effect of fabrication of the RBS connection, on the frame stiffness and lateral displacement of steel bending frames is analyzed. Regarding the high effect of drift on building’s damages, the effect of fabrication of RBS connections on increasing or decreasing of the frame drift are analyzed. In order to investigate the effect of fabrication of RBS connections, the results of RBS connection are compared with the results of cover plate connection.

Keywords: Steel rigid connection; RBS connection; Cover plate connection; Drift; Time History.
