Effect of Hook Angle and Spacing of Transverse Ties of Rc Column in Axial Capacity

Abstract

Effect of different hook angle ties and the spacing of ties is investigated on axial load carrying capacity of RC columns. Axial capacities of sixteen small column and four medium columns are experimentally obtained. The progressions of damage and failure modes are found to depend upon the hook angle of ties and the spacing of transverse reinforcement. The columns with 135° ties bear the more axial load than the columns with 90° ties. Column with 90° ties opened and the longitudinal bars started buckled even in small spacing of ties. Column with 135° ties are found to be more grip to longitudinal reinforcement and they are not opened. Small ties spacing column show the high axial load carrying capacity than the column with large spacing of transverse ties.
