| Summary: | The mechanical property of steel reinforced PP ECC columns under reverse cyclic load is investigated and results are presented in this paper. The influence of reinforcement ratio, curing age and volume fraction of PP fiber on load bearing capacity, energy dissipation and stiffness degradation is investigated. The results highlighted the positive contribution of PP ECC to enhance strength and energy dissipation capacity which is important to evaluate the performance of structures subjected to reverse cyclic loads. According to the experimental study on mechanical behavior of steel reinforced PP ECC columns under reverse cyclic loading, the formula of model parameters related to reinforcement ratio are proposed，it is founded that the restoring force model established is of a certain degree of adaptability. |
