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.
