Seismic Behaviour of RBS and AW-RBS Moment Resistant Connections in Double I-Beams

Abstract:

Moment resistant steel connections are widely used in steel structures and play a significant role in reliability of structures, especially in earthquake-prone regions. After the Northridge earthquake, the invention of Reduced Beam Section (RBS) connections was a turning point in the design of the moment-resistant steel connections. In the present study, the seismic behavior of the RBS connections with reduced flange width as well as the AW-RBS connections with reduced web section in the double section beams are investigated. The results of a numerical study conducted using ABQUS finite element modeling software to investigate the ductility, energy absorption and plastic behavior of the RBS joints under cyclic loads are presented. Results showed promising performance with regards to energy absorbance and ductility for the AW-RBS connections.
