Abstract

The paper presents a few case studies on the seismic response behavior of liquid storage tanks (LSTs), for which not much literature is available. They include (i) the comparison between responses obtained by the 2D-FE analysis and analysis performed according to the procedure recommended by ACI 350.3 for different PGA levels of ground motions; (ii) the comparison between the variations of sloshing heights, base shear, and overturning moment with the PGA obtained by the 2D- and 3D-FE analyses; (iii) the effect of bi- and tri-directional earthquake interactions on different responses; and (iv) the effect of angle of incidence of the earthquake on those responses. The numerical study is conducted with a square tank of size 6 m

Key Words
