SHAKE TABLE TESTS ON THE STEEL FLUİD STORAGE TANK MODELS

Dynamic behaviors of storage tanks under seismic loads are generally complex, which has been studied by many researchers. This issue was first introduced by Housner for cylindrical rigid Tanks. He assumed that the answer to Seismic rigid containers is divided into two impulsive and convective components. Impulsive pressure according to the coordinated movement is part of the generated rigid tanks walls. Convective pressure is also the other part of created fluid at the free surface of the tank contents. In this paper, dynamic behavior of steel cylindrical tank model withdiameter of 1.2 meter and height of 1.25 meters and with fixed roof condition have been tested on the international institute of Earthquake Engineering and Seismology (IIEES) shaking table.In this research, experimental tank model with three different level of liquid height subjected to three different earthquake records.Experimental results including frequency contents, damping values, and sloshing amplitudes have been compared with API650-2008 and ASCE regulations.
