Seismic performance of liquid storage tanks

Cylindrical steel tanks play a significant role in storing chemical products in process industries. Hence, their failure may lead to considerable economic loss due to the operation interruption. On the other hand, those tanks which contain hazardous liquids may encounter explosions and fire disasters as a result of inappropriate structural performance. Strong ground motions are known as potential threats to steel tanks. Catastrophic failures have happened in several tanks following the devastating earthquakes. Accordingly, estimating the seismic performance of such structures has attracted several researchers as well as practicing engineers in recent decades. This chapter focuses on the seismic performance of cylindrical steel tanks.
