Investigation on story shear ratio resisted by BRBs for RC-BRBF structures

摘要：

　　An integration seismic design method of buckling-restrained braced reinforced concrete frame(RC-BRBF)structures is developed by decomposing the total structural system into BRB system and RC frame system using a pre-designated story shear ratio.Using a 5-story story structure as a prototype,14 frames with different story shear ratios were designed,and the design base shears,BRB section areas and reinforcements of RC columns and beams were compared.By performing the nonlinear dynamic analyses under 22 ground motions,the maximum interstory drift ratio,yield mechanism,story shear ratio,the maximum and cumulative displacement ductility of BRBs and the residual drift ratio were systematically investigated for structures with different story shear ratios.Finally,the optimum design story shear ratio was suggested.
