Tension Stiffening Effect of High Strength Concrete

고강도 콘크리트의 인장강성효과에 대한 연구

This paper describes an experimental investigation on the effect of concrete strength on tension stiffening behavior. Total ten direct tension specimens were tested with concrete compressive strength range up to 900kg/$\textrm{cm}^2$. From the experimental program, it was observed that higher strength concrete specimens provides smaller crack spacings and less stiffening effect.
