Abstract

<jats:p>The formation of cracks in concrete structures occurs due to a multitude of causes ranging from shrinkage to external loading and environmental exposure. This phenomenon can significantly affect the lifecycle of concrete structures. Self-healing concrete (SHC) is considered a promoted innovation capable of overcoming this inevitable occurrence. In accordance with current SHC development processes, this paper utilizes the numerical simulation approach to test the performance of reinforced SHC beam specimens modeled using the commercial software ABAQUS 6.14 (Vélizy-Villacoublay, France). This paper aims to contribute to the scarce literature on SHC models by utilizing the overlooked dicyclopentadiene (DCPD) agent and ambiguous variability of crystalline admixtures. The SHC is introduced to the beam models at various depths and analyzed using load against displacement curves compared with a reference model of ordinary concrete. The effects of SHC on the mechanical properties of structural elements were determined. The results show a distinct improvement of the load-carrying capacity of SHC beams, indicating an efficient contribution of SHC in structural applications.</jats:p>
