After brace is applied into the frame structure, its hysteretic curve has an essential change comparing with the traditional structure. For the influence of brace, the shape is full of energy. Furthermore, the capacity of energy consumption is improved to a large degree. The declined part of skeleton line of brace structure will not decline dramatically due to the increase of displacement like the common structure. Instead, the pace of decline slows down. The data show that it can be considered in design to adopt brace instead of shear wall in concrete structure system.Keywords: buckling-restrained brace; reinforced concrete frame structure; experimental study作者簡介：薛彥濤，博士，研究員，Email:yantaoxue@sina.com參考文獻［1］范蘇蓉. 鋼支撐加固鋼筋混凝土框架結構的試驗研究［D]. 南京：南京工業(yè)大學, 2002.
