Link beam web thickness of high strength steel combination Y-eccentrically braced frame mechanical properties of research

In order to study the effects of link beam web thickness to high strength steel combined one-story single-span Y-eccentrically braced frame mechanical properties,using the finite element software ABAQUS to analyse five Y-eccentrically braced frame with different link beam web thickness.The results indicated that the structure had good ductility and energy dissipation capacity,link beam can give fully play to the role of energy consumption and deformation;link beam web thickness have great influence on the strength,stiffness,ductility and energy dissipation performancel,if link beam web thickness is designed reasonably,it can meet the requirements of the action of structure deformation under a small earthquake or the shock,provide good deformation ability and the function of the seismic energy dissipation under a large earthquake.
