EXPERIMENTAL STUDY OF TENON CONNECTION FOR PRECAST MONOLITHIC R.C.FRAME COLUMN
-
摘要: 对以往的装配整体式钢筋混凝土框架柱的榫式接头进行了改进,即把钢筋混凝土榫头改用钢管混凝土榫头,柱纵筋的焊接或冷挤压套筒连接改用滚轧直螺纹套筒连接。低周反复水平荷载作用下的6根框架柱的试验结果以及施工工艺的试验表明,这种榫式柱的受力是可靠的,施工是方便的,可以用于实际工程。最后提出了一些设计和施工建议。Abstract: The traditional tenon connection of precast monolithic R.C.frame columns is improved.In which the concrete-filled steel tubular tenon instead of the R.C.tenon and the longitudinal steel bars connected by rolled parallel thread sleeve instead of welding or sleeve-cold-extruding connection technologies.The test results of 6 frame column specimens subjected to low-cycle reversed horizontal load and the test results of construction technologies show that the suggested tenon connection of frame columns is reliable and convenient,and it can be used in the practical engineering.Some suggestions on design and construction are also proposed.
