Ground-supported open top circular concrete tanks are critical and strategic structures. There tanks are used in the commercial and industrial applications to store a variety of liquids as water or other products such as liquid chemicals and hazardous substance. Damages or collapse of containers may be due to the influence of surrounding aggressive environments or an earthquake. This paper provides numerical model on seismic response of fluid - structure - soil interaction. The article also will be described impact aggressive environment in terms of standards and its impact on the quality of the concrete tank.

The slope stability of a water construction in four cross-profiles is analyzed in the article and the factors of safety reviewed. The GEO 5 software package for slope stability calculations is an essential component of work. The computer software was employed to simulate and calculate the stability in the particular profiles of the downstream and upstream slopes of the Domaša Dam. Bishop, Petterson and Sarma methods were applied to determine the critical factors of safety.
