Compressive Stress-Strain Relation of Concrete Encased Steel Tube Considering the Confining Effect

초록

Concrete encased steel tube has confining effect of concrete and reinforced effect of local bulking. This paper is analyzed compressive stress-strain relation with plain concrete, reinforced concrete, hollow reinforced concrete, concrete encased steel tube and concrete filled steel tube in uniaxial compression load by preceding study. This paper was performed by comparing compressive stress-strain relation in maximum compressive stress and confining effect in each case and considered effect in design
