Application and Research of Reinforced Concrete Frame Braced Structures in Multi-building Design/Zeng Fansheng,Wang Hongqun,Yang Yongzhe(China Northwest Building Design Research Institute，Xi"an 710003,China)

Abstract:On the basis of experimental and research result on reinforced concrete frame and considering different properties of reinforced concrete frame braced structures, the conclusion that the torsion and displacement stiffness can be improved and the bias of irregular plane structures can be regulated effectively using braces in the multi-frame is proposed by analyzing and comparing the mechanic performances of frame structures, frame braced structures and frame shear wall structures. Some advises of braced system applicattion in frame structures design are given.
