Evaluation of existing structures under earthquake loads has an important place in the field of performance-based earthquake engineering. In this respect, linear and non-linear analysis methods can be used in the evaluation of existing structures. Analysis procedures and condition assessment methods for existing structures are thoroughly explained in the Turkish Building Earthquake Code (TBEC-2018). The linear elastic method, which is unique to TBEC-2018, is based on demand parameters of structural elements such as chord rotations and section curvatures. Plastic rotation demands can be calculated using the linear elastic force–deformation relationships and the seismic performance of the structure can be evaluated on the basis of these computed demands. In the scope of this study, the parameters which are used in the application of the linear elastic assessment method are studied. Seismic performance evaluation of an existing school building is carried out using the TBEC-2018 linear elastic assessment procedure. A retrofit project is prepared for the school building and its seismic performance is assessed, as well. Obtained results are then compared with those compiled from the nonlinear dynamic analyses. The comparative investigation reveals that the TBEC-2018 linear elastic assessment procedure is generally successful in estimating the global seismic response as well as individual member plastic rotation demands of the inspected school building.
