Abstract

In this study, a novel retrofitting method are presented to enhance both the structural capacity and construction efficiency for reinforced concrete beams while reducing the use of heavy retrofitting materials and equipment, ultimately contributing to carbon emission reduction. The proposed retrofitting method involves the use of prefabricated components, quickly assembled on-site using bolts and chemical anchors. The structural tests were conducted on three concrete beams, comparing those non-retrofitted specimens. The proposed retrofitting method increased both the maximum load capacity and ductility of reinforced concrete beams. The maximum load capacity of the test specimens retrofitted with the proposed modularized steel plats was found to increased by up to four times compared to un-retrofitted beam. The flexural performance increased by about 1.17 times, depending on the presence of vertical grid. The ductility capacity increased by about 2.5 times.
