This study investigates the mechanical behavior of jute/epoxy laminated composites when applied as external reinforcement to cylindrical concrete specimens subjected to splitting tensile stress. Natural fiber-reinforced composites, such as jute, have gained significant attention in recent years due to their environmental sustainability, low cost, and reasonable mechanical performance. The primary objective of this research is to evaluate the effectiveness of jute laminate sheathing in improving the tensile strength of cylindrical concrete structures using numerical simulation. A finite element method (FEM) approach was implemented in ANSYS Workbench 2022 to model and simulate various configurations, including specimens without laminates and with one, two, and three layers of jute/epoxy laminates. The model geometry was based on standard cylindrical specimens with a diameter of 50 mm and a height of 150 mm. Material properties were defined based on experimental data, and appropriate mesh and boundary conditions were applied. Results showed that the addition of jute laminates significantly enhanced the splitting tensile strength, with the highest increase of 241% observed in specimens with three layers. The simulation results were validated against experimental data using ANOVA, confirming a strong correlation (p = 0.5). This indicates that the ANSYS-based FEM simulation is a reliable tool for predicting the mechanical behavior of natural fiber-reinforced composites in structural applications.

The study demonstrated the crucial role of jute/epoxy laminate composites in enhancing the splitting tensile strength of cylindrical concrete specimens.Numerical simulations using ANSYS Workbench 2022 revealed significant increases in tensile strength with the addition of jute laminates, up to 241% with three layers.The research confirmed the reliability of the finite element method for predicting the behavior of these composites, establishing its potential as a valuable tool for structural engineering applications.

Penelitian lebih lanjut dapat dilakukan untuk menginvestigasi pengaruh variasi orientasi serat jute dalam laminat terhadap kekuatan tarik belah beton, dengan mempertimbangkan sudut serat yang berbeda untuk mengoptimalkan kinerja komposit. Selain itu, studi komparatif perlu dilakukan untuk mengevaluasi efektivitas jute sebagai pengganti serat sintetis seperti serat karbon atau serat kaca dalam aplikasi perkuatan beton, dengan fokus pada aspek biaya, keberlanjutan, dan kinerja jangka panjang. Terakhir, penelitian lanjutan dapat mengeksplorasi penggunaan teknik optimasi berbasis simulasi, seperti algoritma genetika, untuk merancang konfigurasi laminat jute/epoxy yang paling efisien dalam meningkatkan kekuatan tarik belah beton, dengan mempertimbangkan berbagai parameter desain seperti ketebalan lapisan, jenis resin epoksi, dan pola penataan serat, untuk menghasilkan solusi perkuatan yang disesuaikan dengan kebutuhan spesifik struktur beton.
