Diverse Embedment Model for Steel Fiber-Reinforced Concrete in Tension: Model Development

In this paper an analysis model is presented for calculating the response of steel fiber-reinforced concrete (SFRC) members subjected to tension. To predict the tensile stress of fibers across a crack, the pullout behavior of a single fiber with both sides embedded in cracked concrete is analytically investigated, considering both frictional bond behavior and mechanical anchorage effects. Thus, the proposed Diverse Embedment Model (DEM) can be applied to end-hooked and straight fibers. The model is derived with consideration given to all possible fiber orientations and embedment lengths and as influenced by the member’s finite dimensions. The details of the experimental verification for the proposed analysis model, including the proposed fiber orientation factors, are presented and discussed in an accompanying paper.
