Concrete structures wear out due to factors such as earthquakes, strong winds, bearing loads, and fatigue, and they must be strengthened so that they are not damaged or destroyed. One of the best ways to strengthen a concrete building is to use a concrete coating or concrete jacket around structural elements such as columns, beams, and shear walls. Concrete coatings increase the shear and bending resistance of the column and make the column more ductile. The use of concrete coating depends on the conditions and can be implemented all around the column or in one part of the column. The most common use of concrete jackets is their use in strengthening shear walls and building foundations. In the method of strengthening the building with a concrete jacket, weak elements such as beams, columns, shear walls and even the foundation of the building will be strengthened by adding main bars and re-concreting. One of the most important and best advantages of reinforcement with concrete jackets is that this method requires completely homogeneous reinforcement; that is, at the end of the strengthening operation of an element in the building, the new element is also a concrete element. In this research, the strengthening of concrete elements by concrete jackets will be investigated
