Effect of Rubberised Engineered Cementitious Composite (R-ECC) Application as Retrofitting Material on the Structural of Reinforced Concrete Beam-Column Joint Subjected to Static and Cyclic Loading

The beam-column junction in reinforced concrete structures was crucial for structural integrity due to extreme shear stress, and failure can potentially destroy a building. This study aims to determine the crack behavior, load versus displacement, ductility, and equivalent viscous damping of beam-column joints before and after retrofitting with Rubberised Engineered Cementitious Composite (R-ECC) under cyclic load test. The study examines the use of scrap rubber tyres as a partial aggregate substitute. Preparation retrofitting work used 5% of R-ECC by using the R-ECC jacketing and patching method. Research shows that R-ECC retrofitting work enhances reinforced concrete structure's crack behavior and structural performances to higher displacement. Additionally, the cyclic resistance of beam-column joints is greatly increased.
