Abstract：The dynamic mechanical behaviors of reinforced concrete (RC) columns under multi-dimensional dynamic loadings are investigated in this paper. The conclusions can be drawn that, the bearing capacity of RC columns can enhance with the increase of loading rate. The stiffness degradation, strength degradation and damage are significantly higher in the RC columns subjected to rapidly loading. The effect of loading rate on RC columns under bi-directional loading and varying axial loading is more obvious. With the increase of loading rate, the damage region distribute more localized. The ductility and deformation capacity of RC columns decrease obviously with the increase of loading rate, especially in the bi-directional loading with varying axial load.
