Abstract
In this research, the experimental work is on strengthening the Reinforced Concrete (RC) structure by using steel plates in different configuration. Repair or strengthening the Reinforced Concrete (RC) beam had become very common in all country. The RC beams mostly repair by externally retrofit with Fibre Reinforced Polymer and plates. The flexural of the beams can be achieved by using different retrofitting materials. The crack RC beam can be strengthening after repair with FRP or plate. The FRP consist of Carbon Fibre Reinforced polymer (CFRP), Glass Fibre Reinforced Polymer (GFRP), Aramic Fibre Reinforced polymer (AFRP) and also steel plate. In this research, the steel plate was used to repair the cracked beams sample. The concrete grade of all beams is 30MPa. The size of the beams is 150mm x 250mm x2000mm. The beams are cure for 28 days by put the wet cloth on the beams and make sure the cloth is moisture to prevent dehydration. The beams were compress by Frame Testing Machine (FTM) until to get a first crack and stop the machine. The beams were taken out for repair by inject epoxy into cracking part and gun the steel plate on the beams. The steel plate with width 30mm is used. The ten pieces of steel plates were wrapped on each RC beam. There were arranging in two different sequences of U- jacket and L-j acket. The experimental results of this research can be used in the industry to strengthen the cracked beams rather than being demolish. However, further study is needed to carry out to get a better result which having higher strength of RC structure.
