Self-resetting long round steel pipe restrained reinforced concrete column base joint and construction method
The invention relates to a self-resetting long round steel pipe restrained reinforced concrete column base joint and a construction method. The self-resetting long round steel pipe restrained reinforced concrete column base joint comprises a foundation and a long round steel pipe column, wherein a column reinforcement cage is pre-embedded in the long round steel pipe column, a square steel pipe is arranged at the bottom in the long round steel pipe column, an annular area between the square steel pipe and the long round steel pipe column is filled with HPFRCC, column concrete is filled in the square steel pipe and the long circular steel pipe column in the area above the square steel pipe, the column reinforcement cage comprises a plurality of column longitudinal bars I, a plurality of column hoops and two column longitudinal bars II which are symmetrically distributed on the short edges of the two sides of the column reinforcement cage, foundation embedded longitudinal bars are embedded in the foundation, the lower end of each column longitudinal bar I is connected with an SMA bar through a sleeve, each SMA bar is sleeved with a debonding layer, the lower end of each SMA bar is connected with a corresponding foundation embedded longitudinal bar through a sleeve, and each column longitudinal bar II is connected with a corresponding foundation embedded longitudinal bar through a sleeve. The self-resetting long round steel pipe restrained reinforced concrete column base joint is safe, reliable, clear in force transmission, recoverable in deformation after an earthquake, good in bending resistance and tensile property, and good in economic benefit.
本发明涉及一种自复位长圆钢管约束钢筋混凝土柱脚节点及施工方法，包括基础和长圆钢管柱，长圆钢管柱内部预埋有柱钢筋笼，长圆钢管柱内底部设有方形钢管，方形钢管和长圆钢管柱之间的环形区域中填充有HPFRCC，方形钢管内部以及方形钢管上方区域的长圆钢管柱内部填充有柱混凝土；柱钢筋笼包括若干柱纵筋Ⅰ、若干柱箍和两根对称分布在柱钢筋笼两侧短边上的柱纵筋Ⅱ，所述基础内预埋有基础预埋纵筋，每根柱纵筋Ⅰ下端通过套筒与SMA棒材连接，每根SMA棒材上套设有去粘结层，每根SMA棒材下端通过套筒与对应基础预埋纵筋连接；每根柱纵筋Ⅱ通过套筒与对应基础预埋纵筋连接。安全可靠，传力明确，地震后变形可恢复，抗弯与抗拉性能好，具有良好的经济效益。
