In order to investigate the seismic performance of the existing RC buildings more accurately, it is necessary to clarify the mechanical properties of concrete. In this paper, the mechanical properties of concrete from six existing buildings constructed in 1953-1974 before the execution of demolition are discussed. The compressive tests and the splitting tensile tests were performed with the obtained concrete cylinders. Modulus of elasticity, strain at the maximum strength, stress-strain curves and tensile strength are discussed in comparison with the estimated values.
