摘　　要：为了解决框架结构过柔以及框架剪力墙结构中剪力墙过刚、轴压比受限的问题,在区域约束混凝土理论基础上提出了新型的索-区域约束混凝土框架结构。基于ABAQUS对一个区域约束混凝土框架RCC和两种索-区域约束混凝土框架YSRCC,YSRCCS(2)进行数值模拟分析。分析结果表明:设置索能有效提高框架的抗侧刚度、承载力、耗能能力和延性,可大幅度提高建筑的抗震性能并有效的节约建筑材料。In order to solve the problems that the frame structure is too soft and the shear wall is too rigid and the axial compression ratio is limited in the frame shear wall structure. In this paper, a new type of cable-area constrained concrete frame structure is proposed based on the area constrained concrete theory. In this paper, based on ABAQUS, the numerical simulation analysis of an area-constrained concrete frame RCC and two cable-area-constrained concrete frames YSRCC and YSRCCS(2) is carried out. The analysis results show that the installation of cables can effectively improve the lateral stiffness, bearing capacity, energy dissipation capacity and ductility of the frame, greatly improve the seismic performance of the building and effectively save building materials.
