Indonesia is located in an area with a fairly high earthquake intensity, so buildings need to be designed to withstand earthquakes by following existing rules and regulations. However, in the case of non-engineered school buildings, construction is usually carried out without following these rules. So to anticipate casualties due to the earthquake, it is necessary to strengthen non-engineered buildings. This final project is structured to determine the criteria for school buildings that need to be strengthened first. The criteria are determined by looking at the failure mechanism obtained using the pushover method with the help of SAP2000 software. The work stage will start from calculating the P-? relationship of diagonal strut elements and element modeling to determine the moment-curvature relationship of beam and column elements. Then validate the model by comparing the results of the analysis of the wall structure which is modeled as a diagonal strut using SAP2000 with the results of experimental tests. After the modeling of elements and brick walls is validated, it is continued with school modeling. The results obtained are the capacity curve, demand spectrum, distribution of plastic hinges, and the axial force of the compression strut. The results show that the 1-story review school building with the x-axis and y-axis loading directions experienced column failure first on the walls that were given out-of-plane loading. Meanwhile, the 2-storey review school building with the x-axis and y-axis loading directions experienced wall cracks first and there were no failures in the beam and column elements until the end of the analysis.
