Effect of Type of Earthquake Seismic Analysis of Concrete cube shaped Tanks Buried According to the Interaction of Soil Structure

Tanks are generally buried structures to store and maintain large amounts of fluids are used. Therefore play an important role in systems engineering and should play a vital arteries. Failure and failure of such structures after the earthquake, Various losses such as loss of economic, environmental, etc. This search has led the design and analysis of important reservoirs are buried. In this paper, the influence of earthquake time history as the seismic behavior of buried tanks are considered. Thus the three dimensional reservoir modeling concrete cube to the software Abaqus، Effect of the Northridge earthquake, and Elcentro, Chi Chi Considering the interaction of soil and structure has been studied. The process for modeling the effect of soil structure interaction and wave propagation phenomena in the soil around the tank, and direct method of solving viscous absorbing boundary is used. Finally, draw diagrams tank wall deformation and stress, the effect of the earthquake record has been evaluated.
