Stress-Strain Relationships of Concrete Confined by Spiral Reinforcement

나선근으로 횡보강된 콘크리트의 응력-변형도 관계

Axial load-strain relationships of confined concrete with spiral reinforcement were investigated. The main variables were compressive strength of concrete, spacing of hoop reinforcement, and specimen height of plain concrete. The program included tests of eleven confined specimens, and twelve plain specimens, but for all specimens no longitudinal reinforcement was provided. Load-strain curves of confined and plain concrete specimens are reporeted.
