Concrete-filled steel tube bundle composite shear wall with internally-arranged composite confined concrete columns
The invention discloses a concrete-filled steel tube bundle composite shear wall with internally-arranged composite confined concrete columns. The concrete-filled steel tube bundle composite shear wall comprises a composite shear wall body formed by steel tube bundles, the steel tube bundles comprise a plurality of steel tubes, and fiber reinforced composite tubes are fixedly arranged in the steeltubes at the end parts of the composite shear wall body; and when the wall body of the composite shear wall is provided with at least two wall limbs, fiber reinforced composite material tubes are fixedly arranged in the steel tubes located at the intersections of the wall limbs, and each steel pipe and each fiber reinforced composite material tube are filled with concrete. Fiber reinforced composite material confined concrete has good deformation performance and ductility and has the characteristic of obvious later-period rigidity at the same time, the fiber reinforced composite material confined concrete is arranged at one or more positions, such as the wall end, the intersection of two wall limbs and the intersection of the multiple wall limbs, of a deformed or heavily stressed part inthe steel tube bundle composite shear wall; and the fiber reinforced composite material tube is filled with the concrete, so that the composite material tube has the characteristics of high bearing capacity and good ductility.
本发明公开了一种内置复材约束混凝土柱的钢管混凝土束组合剪力墙，包括由钢管束构成的组合剪力墙墙身，钢管束包括若干个钢管，位于组合剪力墙墙身的端部处的钢管内固定设置有纤维增强复合材料管，当组合剪力墙墙身有至少两个墙肢时，位于墙肢的交叉处的钢管内也固定设置有纤维增强复合材料管，每个钢管内和每个纤维增强复合材料管内均充填有混凝土。本发明基于纤维增强复合材料约束混凝土具有良好的变形性能和延性，同时具有明显后期刚度的特点，将其布置在钢管束组合剪力墙内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)的一处或者多处，并在纤维增强复合材料管内填充混凝土，具有承载能力高、延性好的特点。
