SHAKING TABLE TESTING OF CYLINDRICAL STEEL LIQUID STORAGE TANKS
Abstract eng: This paper presents the experimental campaign carried out on cylindrical liquid storage steel tank specimens in CEA TAMARIS facility. Two geometries of tanks have been tested on a shaking table under seismic conditions. The broad tank specimen (diameter 3 m, height 0.9 m) was dedicated to the study of sloshing and potential uplifting during the seism. This specimen was unanchored on the table and free to lift or slide. The influence of a floating roof on sloshing has been studied. The slender specimen (diameter 2 m, height 5 m) was dedicated to the foot buckling of the cylindrical shell. The slender specimen was anchored to the table. All the specimens were water filled. All these specimens were strongly instrumented with inner pressure sensors and wave gauges and outer accelerometers and displacement sensors. In addition a new 3D scanner has been used to detect any residual deformation of the tanks by after / before tests comparisons. The purpose was to give to the calculating teams all the needed measurements and information to check their models. Results acquired on one broad tank and one slender tank are presented here.
