A Study on the Structural Behavior in Mass Concrete Box Rahmen due to Hydration Heat

수화열에 의한 매스콘크리트 박스 라멘 구조물의 구조거동 연구

Concrete cracks due to hydration heat are a serious problem, particularly in mass concrete structures such as box rahmen, dam or footing of pier, etc.. As a result of the temperature rise and restriction condition of foundation, the thermal stress which may induce the cracks can occur. In this, study, ABAQUS program package was used to calculate the temperature distributions generated by hydration heat and the thermal stress in box rahmen structure which have thickness of 1.7~2.2m, and applied for various equations of adiabatic temperature rise such as korean code, japanese code, convection coefficient and low heat cement code.
