Abstract

Abstract: The results of a experimental study on the effect of the drum height on the bearing capacity of composite multi-drum column under axial compression force and lateral horizontal force were presented. Small scale columns with two, four, six and twelve drums were tested. It was concluded that an increased number of drums reduces bearing capacity, flexural and shear stiffness, and increases horizontal and vertical deformability of columns. The reason is the simultaneous increase of the joints number, which are the weakest point in column. The column loaded by axial force only had a brittle failure, and by combined axial force and lateral force more ductile failure. Highlights: The effect of drum height of composite multi-drum stone column was investigated. Columns were exposed to centric pressure and bending. The drum height (number of joints) has a large effect on the bearing capacity and deformability of a stone column.
