Abstract

This paper presents a testing technique to evaluate the effect of loading frequency on the behaviour of structural elements. By subjecting single specimens to alternate frequency loading cycles, the rate effect may be observed more clearly than by comparing the behaviour of different specimens, each loaded at one of the prescribed frequencies. Reinforced concrete (R/C) columns were subjected to uniaxial bending cycles in the range 0.002 to 1 Hz. It was found that the rate effect, as manifested in the measured load and energy absorption, is about 5 % higher when tested at 1 Hz than at 0.002 Hz. The results appear to be little affected by the displacement amplitude.
