摘要：Today Steel moment resistance connections are the most common type of connections that are widely used in steel structures and certainly play a significant role in retrofitting, reliability and economic benefits.It is used also for improvement of the quality and useful life cycle of buildings. Considering the motions importance and after the Northridge earthquake, the invention of RBS connection was a turning point inresistant steel moment connections. This research observes the seismic behavior of the RBS connection with reduced section of flange and a new AW- RBS with reduced section of web in a double section beams that are applicable in Iran. These observations are performed using ABQUS finite elements software. Many models are implemented under cycle loads and ductility. Energy absorption and plastic behavior in the reduced section were observed. Among the studied connections, AW- RBS with the least resistance and stiffness decrement had bearded 8% off the rotation of the story. These models have acceptable behavior in cyclic loads.
