Abstract

The seismic risk of cylindrical concrete tanks on the ground is investigated in this study. Seismic fragility curves are developed for the damage state of bending crack width of the tank wall at the base. Bending crack width is obtained by the nonlinear analysis of reinforcement concrete. The design of the tanks is based on ACI 350.3 and Iranian provisions. Fragility curves are obtained using nonlinear incremental dynamic analysis. The fragility curves of the tanks developed in this study and the existing hazard curves for different regions of Iran were used to calculate the seismic risk. The most important result was the non-uniformity of the risk of the tanks in different zones in Iran. In some zones, the tanks’ failure probability is much higher than in other areas.
