A Study on the Behavior of Shear Link Beam Made of Easy-Going Steel in Eccentrically Braced Frames

Abstract eng:
The design of an eccentrically braced frame is based on creating a frame which will remain essentially elastic outside a well defined link. During extreme loading it is anticipated that the link beam will deform inelastically with significant ductility and energy dissipation. In this study, lower strength steel is used for the link beam according to the general concept of easy-going steel (EGS). The link beam made of easy-going steel yields in less displacement and so the energy dissipation capacity is significantly improved. Non-linear finite element models accounting for large displacements were developed according to the preceding experimental test specimens and the results are compared and good agreement was achieved between the measured and predicted behavior. After verifying the FE models, pushover and cyclic analysis was carried out for various link beam models made of ST37 steel and EGS. It was observed that the links made of easy-going steel had significantly better behavior. No local buckling was observed in the links and the hysteretic loops were stable.
