Construction Engineer/Manager Keramettin Gençtürk from Yapı Güç Mühendislik made a statement regarding the reinforcement to be done in moderately damaged buildings after the earthquake. Civil Engineer/Manager Keramettin Gençtürk stated, “Our country is an earthquake zone. Earthquakes are a law of nature. To avoid being affected by earthquakes, we must make all our structures earthquake-resistant. Our current agenda is to make our structures, which we could not make earthquake-resistant and which were affected by the earthquake, earthquake-resistant. In this process, we must present a unique examination and solution for each structure. Namely, the structure should be examined and analyzed in every aspect, and the conclusion should be: 1- The structure is solid; no action is required, 2- The structure is risky; reinforcement should be made, 3- The structure is not solid; it should be demolished. Today, we want to discuss the evaluation of existing structural systems under the impact of earthquakes and recommendations on strengthening. This includes the rules that must be applied not only to structures classified as moderately damaged, as in Elazığ, but to all existing structures. First, we can classify structures into three categories: A-) Masonry Structures, B-) Steel Structures, C-) Reinforced Concrete Structures. We must determine the capacity of the existing structure's load-bearing system elements. Details and dimensions of the structural element, the geometry and material properties of the load-bearing system, experimental data, determination of the foundation system and soil properties, determination of damage (in structures classified as moderate and light damage), checking its suitability for the project, if any, and determining the level of knowledge of the structure as a result of these data; in other words, determining the limited or comprehensive level of knowledge. Reinforced concrete structures; -Geometry (relief) -Element details -Detection of reinforcement in columns and walls (5% stripping - 20% detection with a device) -Concrete material properties; (at least 3 concrete samples from columns and walls from each floor with core drilling and not less than 3 on the ground floor and 2 from other floors, totaling not less than 9, with 1 core drilling per 400 m2.) -Detections are made in steel structures as in reinforced concrete structures. In addition, 20% of the element details are dimensional checked and welded or Tests are performed by taking samples from bolts. In the determination of masonry structures, survey; element details, slab type, wall connections, beam, and wall material types are determined along with survey rules for reinforced concrete and steel structures. Following all these, damage limits and damage areas of structural elements are determined. As follows; -Limited damage (SH): limited inelastic behavior in the section, -Controlled damage (KH): safe inelastic behavior of the section strength, -Pre-collapse damage (GÖ): shows advanced inelastic behavior in the section. After these determinations, the strengthening criteria of the structure are designed according to the minimum performance targets stipulated in the Turkish Building Earthquake Code for the targeted earthquake performance in existing or to be strengthened structures, and the calculation phase is moved on. Thus, in the strengthening phase of structures; -Remediation of defects that may be caused by earthquake damage -Ensuring continuity by adding new elements to increase earthquake safety are examined. Strengthening Types: -Ensuring the element strength to withstand the earthquake load of column, beam, shear wall joints (Element strengthening) -Increasing the load-bearing system strength and deformation capacity of the structure. Adding new elements to the structure, strengthening the joints, reducing the mass of the structure in order to reduce the effect of an earthquake (System strengthening) 1-) Strengthening of columns; -Reinforc
