Concrete-filled steel tube bundle composite shear wall with internally-arranged composite tube confined combined steel and concrete columns
The invention discloses a concrete-filled steel tube bundle composite shear wall with internally-arranged composite tube confined combined steel and concrete columns. The concrete-filled steel tube bundle composite shear wall comprises a steel tube bundle composite shear wall body, fiber reinforced composite material tubes internally arranged in the wall body and steel ribs. One or more fiber reinforced composite material tubes are arranged at one or more of the deformed or heavily stressed parts of the concrete-filled steel tube bundle composite shear wall, such as the wall end, the intersection of two wall limbs and the intersection of the multiple wall limbs, and profile steel is arranged in the fiber reinforced composite material tubes; and the bearing capacity and the ductility of thecomposite wall are enhanced by utilizing the characteristics of good strength and ductility of the composite confined concrete, and the bearing capacity, the ductility, the bending resistance and theaxial rigidity of the composite wall are further enhanced by utilizing the profile steel arranged in the fiber reinforced composite tube confined concrete column. The composite confined concrete hasthe characteristic of stress-strain strengthening, and the composite wall further has the self-resetting function during a large earthquake.
本发明公开了内置复材管约束钢骨混凝土柱的钢管混凝土束组合剪力墙，包括钢管束组合剪力墙墙身、内置于墙身的纤维增强复合材料管和钢骨。本发明通过在钢管混凝土束组合剪力墙变形或者受力较大部位，如墙端、两个墙肢交叉处、多个墙肢交叉处位置中的一处或者多处布置一个或多个纤维增强复合材料管，并在纤维增强复合材料管内布置型钢，利用复材约束混凝土强度、延性好的特点来增强组合墙的承载力和延性，并利用置于纤维增强复合材料管约束混凝土柱内的型钢来进一步增强其承载力、延性、抗弯及轴向刚度。由于复材约束混凝土具有的应力‑应变强化特点，本发明提出的组合墙还具有大震时的自复位功能。
