Abstract:
For a connection of a column and pile made of concrete-filled steel pipes with different diameters, a simple overlap joint in which a smaller diameter pipe is inserted by the specific length to a larger diameter pipe with concrete filled between them has been proposed as an economical and effective joint system. In the present paper, the load- carrying capacities and failure mechanisms of the present joint system are experimentally investigated. The experiments indicate that the ultimate and yield loads increase proportionally with the increase of the overlap length and the wall thickness of pile pipes. In addition, a method to predict ultimate loads of the present joints has been proposed.
