Abstract: 

Eccentrically braced frames have high stiffness and suitable energy damping against the lateral forces like the earthquake. In this bracing system, the required stiffness and formability of the frame is provided by the link beam, and are dependent on the details and characteristics of the link beam. In recent years, Eccentrically Braced Frames (EBF) has been utilized as a resistant system against the earthquake lateral forces. In this paper, using non-linear static analysis, the behavior factors of MRF, CBF, and EBF frames in some models are investigated. These studies are carried on three-storey, six-storey, and ten-storey models, statically linear and non-linear. The results indicate that the EBF behavior factor is largely affected by the link beam. It is also concluded by the investigating of relative and overall displacements of the mentioned models that these parameters are dependent greatly on the length of the link beam.
