Experimental study of hysteretic energy absorption and load capacity of reinforced concrete columns subjected to different cyclic loading rates
Full-scale cyclic tests on five reinforced concrete slender column elements were carried out at 0.002 and 0.2 Hz at displacement amplitudes sufficient to cause considerable damage. The effect of the loading rate was studied with reference to the envelope of the load carrying capacity, and the distribution of the rotation along the column length. The equivalent viscous damping associated with the hysteretic behaviour was found to be rate independent in the range studied. The structural degradation was represented as a function of the cyclic stiffness normalised by the elastic stiffness.
