Nonlinear Time History Analysis Of High-rise RC Frames With Y-eccentrically Brace

At present, the research of the steel brace mainly concentrated in the steel braced frame construction. The link beam was used to improve the rigidity and carrying capacity of structure, through shear-yield of link beam ,the brace realize to dissipate energy and improve the seismic performance of structures. In recent years, the transformation of RC frame structure use the merits of link beam brace and the research of RC frames with Y-eccentrically brace was extremely limited at home and abroad. So the research of RC frames with Y-eccentrically brace is particularly important and necessary.In this paper, the nonlinear time history analysis of RC Frames with Y-eccentrically brace are analysized by SAP2000V14 finite element, Through the earthquake loading, Some influencies were measured,Such as,floor displacement of structure,floor shearforce, shear-carrying capacity ratio on link beam and the change of columus shearforce. According to the data compared by analysis, several conclusions were obtained.It provided the references for relevant researchers and designers.
