Abstract. In Turkey, after two big earthquakes centered on Kahramanmaraş on February 6, 2023, a catastrophic damage occurred and more than fifty thousand people passed away, and a lot of people lost their comfort of life even though they were rescued from the rubble. It has been emphasized by scientists that this great destruction, in almost all types of structures such as concrete, steel, stacking and prefabricated, is usually caused by design errors, poor material quality and workmanship. In this study, design errors and damage modes of reinforced concrete structures in Malatya were examined with a field study. During the fieldwork, it was determined that reinforced concrete structures were generally damaged or collapsed due to inadequate longitudinal reinforcement and stirrup, poor reinforcement and concrete quality, design errors in the column-beam joint region (strong beam-weak column and lack of stirrup spacing), torsional irregularity, ignoring the soil-structure interaction and soft storey.
