Development of Test Device for Response to Structural Behavior of Constrained that can Apply Zero-Span Tension Conditions

무절점 인장응력 조건의 적용이 가능한 구속형 구조물 균열 거동 대응 성능 시험 장치 개발

The existing evaluation method could not apply the effect of zero span tension generated in the waterproofing layer attached to the surface of the structure at the moment of cracking as the waterproofing layer was constructed in the state where the cracks were formed. The test apparatus developed through this study is expected to be able to conduct tests closer to the environment occurring in actual structures as it is possible to simultaneously create a pressurized (constrained) condition and an environment for zero span tension.
