Research on the Seismic Behaviors of Link Beam for Eccentrically Braced Low Yield Point Steel Frames
It was performed nonlinear finite element analysis for K-shape eccentrically braced steel frames on link beam. Analysis indicates that the strength, rigidity, ductility and energy-dissipation performance of K shape eccentrically braced steel frames deteriorate differently with the length increase of link beam. The shorter the link beam is, the larger plastic deformation of it, so it makes plastic collapse easily, while a long link beam has a poor cyclic behavior. At the end of this paper, compared with the experimental results show that the finite element method is feasible, the results can provide a reference for the engineering design and related research.
