EXPERIMENTAL LOAD-CARRYING CAPACITY AND DYNAMIC EFFECT COEFFICIENT OF RC SLAB AND RC BEAM UNDER RUNNING VIBRATION-LOAD

Abstract

The authors conducted running constant-load and vibration-load tests on RC beams and slabs to quantitatively evaluate the experimental load-carrying capacity and the dynamic effect. The load-carrying capacity of the beams and slabs under running vibration-load was nearly approximate to the maximum running constant-load and upper limit running vibration-load. The dynamic effect of running vibration-load was evaluated from the experimental impact coefficient based on deflections. The experimental impact coefficient of RC beams and slabs was approximately 0.24 to 0.49. Because it was larger than the amplitude of working load, the authors evaluated a dynamic effect coefficient as a function of load amplitude.
