摘要
在钢筋混凝土剪力墙中两端设置型钢暗柱、中部设置钢板,形成钢-混凝土组合剪力墙结构,能充分发挥钢-混凝土组合结构优势,提高剪力墙承载力,减小截面厚度,改善结构抗震性能。采用有限元软件ABAQUS对平安金融中心核心筒区域钢-混凝土组合剪力墙进行了计算分析。结果表明,对于钢-混凝土组合剪力墙,只要构造设计合理,内埋的型钢、钢板与钢筋混凝土在达到极限承载力前是协同工作的。
With embedded steel columns in two ends and steel plate in the middle plane of shear wall,steel-concrete composite shear wall structure can exploit the advantages of steel-concrete composite structure,including increase of the bearing capacity of shear wall,decrease of the thickness and improvement of the seismic performance of the structure.Calculation and analysis were conducted on steel-concrete composite shear wall in the core wall area of Ping' an Financal Center using finite element software ABAQUS. The results show that with reasonable seismic measures,the embedded steel columns,plates and reinforced concrete can work together before reaching ultimate bearing capacity.
