A study has been undertaken to determine the shear behavior of reinforced concrete beams subjected to high temperatures at one side. A total of nine specimens was tested. The parameters of the tests were (1) heating temperature (65, 90 175°C) and (2) heating period (1, 3, 6 or 12 months). Different combinations of these parameters were employed, and the shear strength deterioration rate was evaluated. The test results were confirmed by a non-linear finite element analysis. The relationship between the concrete compressive strength, which varied from heating face to upper portion, and the shear strength in specimens was discussed. To propose the shear design of the massive members like the Nuclear Power Plant Building, the massive concrete core test were confirmed. It is practicable that the relationship between the core compressive strength and the temperature in the core tests is used on the shear design.
