In order to determine the dynamic performance of rubber fiber reinforced concrete （RFRC） under compression， four kinds of rubber fiber reinforced concrete were prepared according to 0%， 30% rubber substitution rate and 0%， 0.6% polypropylene fiber content respectively under eight earthquake loading strain rates. According to the test results， the failure modes and stress-strain curves of rubber fiber reinforced concrete under different loading conditions are obtained. Through comparative analysis of the mechanical parameters of rubber fiber reinforced concrete under different loading conditions， the following conclusions are obtained： the integrity of rubber particle and polypropylene fiber reinforced concrete under static and dynamic pressure is relatively high， and the rubber particle can effectively improve the extension of concrete with the increase of loading strain rate， the peak stress of rubber fiber reinforced concrete increases gradually. The dynamic improvement coefficients of peak stress and elastic modulus of concrete with polypropylene fiber are significantly higher than those of other mixing conditions， whereas the situation for concrete with rubber particles is just the opposite. At the same time， the relationship equations between the loading strain rate and the dynamic improvement coefficients of peak stress and elastic modulus are put forward respectively， and the stress mechanism is discussed.
