Investigate the effect of foundation and tank concrete hardness on the seismic response of high tanks using probabilistic analysis

Water tanks are among the main components of water supply networks for storing, maintaining and supplying pressure, and these structures should have the ability to exploit and supply pressure in the water supply network after the earthquake. In this paper, the effect of foundation concrete hardness...

description	Water tanks are among the main components of water supply networks for storing, maintaining and supplying pressure, and these structures should have the ability to exploit and supply pressure in the water supply network after the earthquake. In this paper, the effect of foundation concrete hardness to tank concrete hardness on seismic analysis of air tanks has been investigated. In the current seismic analysis, the relationship between the concrete hardness of the foundation and the concrete of the tank body is expressed by the definition of the constant coefficient K. By changing this coefficient, its effect on each of the tensile/compressive stress, and displacement parameters using a probabilistic analysis is examined. The tank is modeled using a three-dimensional finite element method based on ANSYS software. In this model, the interaction between the tank body, fluid and foundation are considered and the accelerogram of Manjil earthquake in the intended model is used to apply the earthquake. The probabilistic analysis used in this study is Monte Carlo simulator using the Latin hypercube sampling method and K coefficient is used as an input variable. The maximum horizontal displacement of the structure, the maximum 1st principle stress and the maximum 3rd principle stress are selected as critical responses and output variables. The results of analyzing models and comparing responses such as maximum principle stresses and maximum displacement show that with regard to economic considerations and the appropriate reliability coefficient for the system, the most efficient and optimal value for the coefficient K is approximately 0.7.
