Abstract:At present, buckling restrained braces are widely used in new and strengthened reinforced concrete frame structures, which becomes the reinforced concrete frame structure with buckling restrained braces. In view of the fact that the design method of this kind of structure is not clearly specified in the code. Some design recommendations on the basis of experimental research and design practice was proposed, which includes different design methods should be adopted according to the performance of buckling restrained braces, applicable height of structure, arrangement method and requirements of buckling restrained braces, calculation assumption of buckling restrained braces under small earthquake, limit value of floor displacement angle, different inspection requirements of buckling restrained braces according to different performance, connection design between braces and structure, seismic measures of reinforced concrete frame.

Keywords:buckling restrained brace;reinforced concrete frame structure;seismic reinforcement;energy dissipation
