ABSTRACT: : Liquid Storage tanks are common and very important structures in industrial, commercial and lifeline sites. Because of their key function in industry and the importance of the liquids they contain; several studies have been conducted on the dynamic behavior of these thin shell structures. This study reports a series of shaking table tests carried out on precise-scaled models of a cylindrical flexible petrochemical liquid storage tank. These models were tested using a cylindrical laminated box. The experiments were repeated for different intensities of input motion. The results demonstrated that site conditions can considerably affect the seismic performance of these structures and their failure modes.

RÉSUMÉ: Tanques de almacenamiento liquido son estructuras comunes y muy importantes en los sitios industriales, commerciales, y lineas de vida. Dado a su funccion clave en la industria y la importancia de los liquidos que contienen, varios estudios han sido conducidos en el comportamiento dinamico de estas estructuras de armazón delgado. El estudio consiste de un serie de experimentos con mesas que agitan modelos de precisa escala de un tanque flexible petroquimico de almacen cilindrical. Estos modelos fueron probados en una caja de lamina cilíndrica. Los experimentos fueron repetidos con diferentes intensidades de aporte de movimiento. Los resultados demostraron que las condiciones del sitio pueden afectar considerablemente el desempeño sísmico y modos de falla de estas estructuras.
