Rubberised Engineered Cementitious Composite (R-ECC) As Retrofitting Material for Reinforced Concrete Beam-Column Joint Subjected to Cyclic Loading

Year: 2025

Type: article

Abstract: Earthquakes present significant risks to infrastructure and human safety, highlighting the need for effective disaster mitigation strategies. This study explores the utilization of scrap rubber tires as a partial replacement for aggregate in concrete. The primary objective is to analyze the load-displacement behavior and structural performance of RC beams before and after retrofitting with Rubberized Engineered Cementitious Composite (R-ECC) under fatigue loading. The testing procedure included static and fatigue load assessments using a four-point bending test. The retrofitting process incorporated 5% R-ECC. Findings indicate that R-ECC retrofitting improves concrete's ductility, load-displacement response, and flexural fatigue strength, resulting in greater displacement capacity and increased deformation before failure.
