Stress–Strain Behavior of Helically Confined RPC Columns Reinforced with Steel Fibers under Concentric Loading

Journal Article


Abstract


  • In this paper, an analytical stress–strain model is proposed that emphasizes the influence of steel fibers of different geometry and

    volume content on the behavior of the confined reactive powder concrete (RPC) columns. The proposed model takes into account the influence

    of the geometry and volume content of steel fiber on the behavior of the confined RPC column in terms of peak load, corresponding

    deformation, and post peak behavior. The behavior of the confined RPC columns reinforced with different types of steel fiber subjected to

    concentric loading is represented analytically. The analytical behavior of the fibrous RPC columns is verified with the results obtained

    experimentally from the literature. The outcomes show that the proposed analytical model to present the behavior of confined fibrous

    RPC columns is in very good agreement with the results obtained experimentally.
