چکیده انگلیسی
Aboveground steel storage tanks are widely utilized in industrial areas such as oil refineries, petrochemical complexes, oil depots, and etc. Assurance of these infrastructure facilities in high seismic areas is a very important engineering consideration. High amplitude fluid sloshing is one of the widespread causes of steel oil storage tanks during strong earthquakes addressed as an important failure mode. This phenomenon generates additional forces impacting the wall and roof of the tanks. Annular baffles can be used as slosh damping devises to control liquid sloshing within a tank. The main objective of this paper is experimental study of annular baffle effects as anti-sloshing damping devices to reduce fluid wave sloshing height in steel storage tanks typically used in oil and petrochemical complexes during an earthquake. Shake table tests have been used on a reduced scale model steel storage tank in two cases of with and without annular baffles. Three real earthquake ground motion records are used as input base motion. Based on the experimental test results, dynamic characteristics of studied tank models with different filling levels and different baffle dimensions and arrangements have been obtained and summarized in this paper. Also, sloshing heights and convective mode damping values are determined from the test results and compared with API650 code recommendations and recommended equations by other researchers. Generally, the results of this study indicate significant effects of the annular baffles in reducing the fluid wave sloshing height as sloshing dependent variable dampers.
