Abstract

Eccentrically Braced Frame (EBF) is one of seismic resistance of steel structures. Dissipation of seismic energies is designed by allowing plastic hinges to form in link element. Design of link elements allow plastic hinge to form due to shear or flexural failure. Structural analysis using finite element software require shear plastic hinges to be modelled. It is found that hinge properties proposed by two references, FEMA 356 and Richards & Uang are different. Study of effect of hinge properties on non-linier analysis of EBF was performed. The research is limited to hinge properties of shear link of EBFs. Numerical study was conducted on one and three storey of EBFs in two and three dimensional geometric of EBFs. Two different hinge properties from FEMA 356 and Richard-Uang were compared each other. Results show that hinge properties affect the structural response. It is found that EBFs modelled by hinge properties according to Richards-Uang has close result to experimental result than modelled built by FEMA 356. The difference between FEMA 356 and Richard-Uang to experiment are 34,54% and 15,55%, respectively.
