摘　　要：目前建筑行业大力推广高层、超高层建筑,对具有更优的抗震性能结构体系研发工作显得更为迫切和重要,为此,提出了组合框架双开孔钢板约束混凝土墙结构的高效新型双重抗震防线抗侧力结构体系,考虑组合剪力墙不同连接方式、轴压比两个设计参数,采用ABAQUS对该结构体系的抗震性能进行研究分析。研究结果显示:①四边连接试件相较两边连接试件周边整体约束强、整体性好,钢板拉力带的发展更为均匀且充分,四边连接试件的承载力、抗侧刚度、耗能能力均高于两边连接试件;②随着轴压比的增大,承载力、抗侧刚度略微增强,但耗能发展减缓。Based on the current construction industry vigorously promote high-level,high-rise buildings,with better seismic performance of structure system research and development work is more urgent and important,therefore,this paper proposes a combination framework double efficient of the perforated plate wall structure of confined concrete new dual seismic line structure system to resist lateral force,consider different ways of connection between composite shear wall,axial compression ratio,two design parameters,the seismic performance of the structure system was studied by using ABAQUS.The results show that:①compared with the specimens with two sides,the four-side connection specimens have strong overall constraints and good integrity,and the development of tensile bands of steel plates is more uniform and full.The bearing capacity,lateral stiffness and energy dissipation capacity of four-side connection specimens are higher than those with two sides.②With the increase of axial compression ratio,the bearing capacity and initial lateral stiffness increase slightly,but the energy consumption slows down.
