THE SEISMIC PERFORMANCE EVALUATION OF AN ECCENTRICALLY BRACED STEEL FRAME BY NON-LINEAR DYNAMIC ANALYSIS

The goal of this paper is to investigate the non-linear response and to assess the seismic performance of a six story eccentrically braced steel frame (ebf). for this, split-k-braced ebf with high ductility level designed according to the turkish earthquake code-2007 (tec-07) is analyzed under seven selected earthquake records. the performance of the ebf is assessed considering drift, story and base shear demands, brace and column axial forces and bending moment demands, link beam shear force and rotation demands. mean values of the demands are used in the performance assessment. the provisions based on capacity design approach specified in tec-07 for ebfs with high ductility level are discussed by employing the findings..
