INFLUENCE OF WALL FLEXIBILITY OF LIQUID STORAGE TANKS ON HYDRODYNAMIC PRESSURES INDUCED DURING SEISMIC ACTIVITY
Abstract eng: The paper deals with the seismic analysis of the circular vertical ground-supported tanks containing liquid with the aim to determine the distribution of hydrodynamic pressures along the tank height during seismic excitation. Circular tanks are used for storage of liquids in various industrial sectors. Hence, it is a request for satisfactory performance during dynamic loadings. In general, these tanks are usually made of reinforced concrete or steel. For determination of distribution of hydrodynamic pressures there must be distinguished between rigid and flexible tanks due to different responses of tank-liquid systems. In cases of flexible tanks, the wall flexibility is taken into account. The paper is also dedicated to compare results of distribution of hydrodynamic pressure for both cases assuming models with identical geometric proportions. For computation and subsequent comparison Eurocode 8 standard and other procedures are used.
