Stress–Strain Behavior of Helically Confined RPC Columns Reinforced with Steel Fibers under Concentric Loading
Publication: Journal of Materials in Civil Engineering
Volume 32, Issue 6
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.
