Abstract
This paper reports about experimental results carried out in order to obtain data about the failure behavior of concrete column reinforced with strands which have higher tensile strength and lower bond strength with concrete than usual deformed bars. The following things about failure behavior was made clear, 1) cracking locally, 2) distance from neutral axis and strain in the cross section are not in proportion, 3) residual displacement in small, 4) energy Absorption per each hysteresis loop is small, 5) yield displacement is large. And if both ends of each strand were anchored firmly, ultimate bending strength can be calculated by the way of calculating it which distance from neutral axis and strain in a cross section are in proportion is suppposed.
