This paper presents the performance assessment of a mechanically stabilized earth (MSE) wall in highly seismic region in Türkiye. Wall performance under static and seismic conditions was searched with finite element and limit equilibrium analysis. Performance results of static case were compared with the lateral displacement limitations stipulated by some standards and specifications. On the other hand, lateral movement of wall after extreme seismic event was evaluated depending on post-earthquake investigation and shaking table testing due to the lack of deformation analysis-based regulations. The analyzed wall section in 23.95 m height is expected to experience no damage to moderate damage level without collapse with 2.1 cm for static case and 50.9 cm for an earthquake with the peak ground acceleration value of 0.533g. This case study shows that the performance of high single-tiered MSE walls is satisfactory even under high seismic actions.
