摘　　要：外包钢板混凝土组合剪力墙是在混凝土剪力墙的外部外包钢板,沿墙长方向设置加劲肋板或隔板,形成多个腔体,在腔体内浇筑混凝土,并采用栓钉、加劲肋、隔板等次要构件来加强混凝土与外包钢板的黏接,防止钢板平面外屈曲。以1180 m高的中国建筑千米级摩天大楼为载体,研究外包钢板混凝土组合剪力墙的构造特点、在设计软件中简化措施、设计方法,并进行了试验研究。研究表明,外包钢板混凝土组合剪力墙强度高、延性好、施工简单等特点,具有良好的抗震性能。The concrete-filled steel plate composite shear wall is a kind of concrete shear wall with outer steel plate,stiffening ribs or partitions are arranged along the long direction of the wall to form multiple cavities.Concrete is poured into the cavity.Secondary components such as bolts,stiffening ribs and partitions are used to strengthen the bonding between concrete and outer steel plate,so as to prevent the steel plate from outside the plane buckling.Based on the 1180 meters high skyscraper of CSCEC,experimental study was carried on the structural characteristics,simplify and design methods used in design software,research shows that the concrete-filled steel plate composite shear wall has characteristics of high strength and stiffness,good ductility,construction convenience,good seismic performance.
