预制混凝土构件通常采用先拼接后灌浆的连接方式,一旦灌浆不密实,将存在严重安全隐患。为了解决装配式复式钢管混凝土结构的连接问题,探索更方便可靠的连接方式,将先灌浆后插筋的连接方式运用到装配式复式钢管混凝土柱的连接中,系统研究了该连接方式下装配式复式钢管混凝土柱中的钢筋锚固性能和锚固长度。并通过设计制作36个复式钢管混凝土柱的灌浆插筋锚固试件,采用拉拔试验方法研究了钢筋直径、位置、锚固长度、预制孔形式及直径、灌浆料强度、混凝土强度7个影响因素对浆锚钢筋在复式钢管混凝土柱中的锚固性能影响。研究结果表明:(1)试件的典型破坏形式包括钢筋未屈服拔出、钢筋受拉屈服拔出、钢筋拉断三种形式,主要发生钢筋屈服后试件破坏,锚固性能良好;(2)浆锚钢筋在灌浆料中的受力过程主要分为四个阶段:弹性阶段、屈服阶段、强化阶段和破坏阶段;(3)预制孔直径、混凝土强度、灌浆料强度越大,锚固钢筋锚固性能越好;(4)角部浆锚钢筋的极限承载力和极限黏结应力均比中部浆锚钢筋大;(5)复合钢管混凝土柱装配式连接的锚固长度建议根据《混凝土结构设计规范》进行计算确定,且预制孔直径不小于2

The traditional prefabricated RC structures were anchored by cement injection, but incomplete grouting posed significant safety risks. In order to solve the connection problem of the assembled composite-sectioned concrete-filled steel tubular (CS-CFST) structure and explore a more convenient and reliable connection mode, this paper applied the connection mode of grouting first and then inserting reinforcement to connect the assembled CS-CFST columns, and systematically studied the anchorage performance of the reinforcement in the assembled CS-CFST columns under this connection mode. By designing 36 groups of grouting before inserted rebar anchorage specimens of CS-CFST columns and using pull-out test method, the influence of seven factors on the anchorage performance of the grout anchored steel bars in the CS-CFST columns were systematically studied, including rebar diameter, position and rebar anchorage length, prefabricated hole form and diameter, grouting material strength and concrete strength. The results show that: (1) Three typical failure modes are identified, including the inserted rebar being pull out without yielding, the inserted rebar being pull out after yielding, and the tensile rupture of the inserted rebar. (2) The stress process of mortar anchor reinforcement in grouting material is mainly divided into four stages: elastic stage, yield stage, strengthening stage and failure stage. (3) The anchorage performance improves with larger prefabricated hole diameters and stronger grouting material and concrete. (4) The ultimate bearing capacity and ultimate bond stress of the anchored rebar in the corner are larger than those in the middle of the steel side; (5) The anchorage length of the fabricated connection of concrete filled steel tubular composite column is recommended to be determined according to GB50010-2010, and the dimeter of the prefabricated holes is more than 2 times of the inserted rebar diameter, and no less than 32mm.
