Variation law of mechanical properties of concrete under different stress amplitudes. (a) Variation law of loading elastic modulus EF of concrete with the cycle number C under different stress amplitudes. (b) Variation law of unloading elastic modulus EC of concrete with the cycle number C under different stress amplitudes. (c) Variation law of peak strain of concrete with the cycle number C under different stress amplitudes. (d) Variation law of residual plastic deformation of concrete with the cycle number C under different stress amplitudes.
