Finite Element Analysis of Recycled Coarse Aggregate in Concrete

<p><span lang="EN-US">This research investigates the structural performance of concrete incorporating recycled coarse aggregate (RCA) through finite element analysis (FEA) with increasing emphasis on sustainable construction practices, RCA presents an eco-friendly alternative to natural aggregates. A numerical model was developed using SAP2000 to simulate the behavior of RCA concrete under compressive loading. Experimental results were used to calibrate and validate the model. The analysis revealed that RCA concrete exhibits slightly lower stiffness but comparable load-bearing capacity to natural aggregate concrete. The findings support the feasibility of RCA in structural applications, contributing to sustainable development in the construction industry.</span></p>
