Experimental Study On Reinforced Concrete 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 reinforced concrete frame structure use the merits of link beam brace and the research of reinforced concrete 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.Through the comparative study of the one reinforced concrete frames and the two reinforced concrete frames with Y-eccentrically brace,which have the same shapes,materials,dimension,several parameters of these frame behavior,such as side stiffness,limit load and energy consume ability,were studied.At the same time, the nonlinear analysis of reinforced concrete frames with Y-eccentrically brace are analysized by ANSYS 10.0 finite element.Through the lowly circular and repeates loading,the load bearing,deformation,and ducrility of the reinforced concrete frames and the reinforced concrete frames with Y-eccentrically brace were measured.Based on the results,several conclusions were obtained.It provided the references for relevant researchers and designers.Through the ansysis by ANSYS 10.0 finite element,it is proved that it is feasible.
