A Method of Restoring a Reinforced Concrete Beam with Local Damage During Combat Impacts

The rehabilitation and repairing of reinforced concrete elements is an old term that was carried out in a lot of research. As a result of a long time of research, many books and literature have turned out with different methods of repairing damaged elements that resolve various cases. Rehabilitation and repairing of the structure could be needed in the reconstruction of old and outcast buildings or sometime as a result of urgent cases such as big fires, gas explosions, combat forces….Urgent situation as explosions (combat, gas, or in one or another case), a reinforced concrete element can lose part of itself, preserving the bearing capacity in the remaining part of him. Rehabilitation of such cases has rarely been mentioned in reference therefore in our research we worked on an approach based on the repairing method by changing the design scheme of the element/structure. Based on our proposed approach we ran a series of experiments on reinforced concrete beams with a cross-section size (70x120) mm and a length of 2800mm. The experiments included different cases of damage and different percentages. Laboratory experiments justified the theoretical expectations of the proposed method with different percent of effective between the different cases of damage.
