HERNANDEZ BARRIOS, Hugo. Seismic response of inverted pendulum-type elevated tanks. Ing. sísm [online]. 2018, n.99, pp.1-22. ISSN 0185-092X.

The majority of elevated tanks are regarded as essential facilities, and therefore, they must be functional even after a major earthquake. Elevated liquid storage tanks have a vital role for storage of water and other liquids for use in military bases, industrial companies, nuclear reactor installations and water supply facilities. Elevated tanks are different from ground-based tanks because they consist of two main parts: the tower and the stiffness vessel. In the past few decades, numerous incidents of earthquake damage sustained by elevated tanks have been reported. In this paper an analytical mechanical model for tanks is developed taking into consideration the effect of both rocking motion and lateral translation. The results showed the importance of considerate on the movement equation three convective modes of liquid, principally in Mexico City zone, also the importance of considerate the rocking contribution of the vessel base on the moment foundation.

Palabras llave : elevated tanks; inverted pendulum; rocking motion.
