Seismic Performance of Cylindrical Liquid Storage Tanks in the 2023 Kahramanmaras Earthquakes: A Case Study of a Self-Supported Oil Storage Tank

This paper covers the seismic performance of liquid tanks due to 2023 T & uuml;rkiye earthquakes and a case study of a moderately damaged self-supported tank is studied. Typical types of damage were sloshing induced upper tank wall deformations, sliding and uplift of the base, and rupture at tank-pipe connections. Besides, slip-prone tanks were less vulnerable to tank damage. The coupling between sliding and uplift responses of a self-supported tank is investigated considering different coefficients of friction. The results revealed that tank wall stresses can be significantly reduced due to sliding effect.
