PLoS ONE 17(3):Įditor: Ahad Javanmardi, Fuzhou University, CHINA This method can ensure the accuracy and reliability of hydrodynamic pressure calculation.Ĭitation: Gao L, Chen Z, Yang H, Wan X, Wang M (2022) Hydrodynamic pressure law of ground-rested circular RC tank under bi-directional horizontal seismic action. Total hydrodynamic pressure under bi-directional horizontal seismic action is obtained by the square root of the sum of X-direction hydrodynamic pressure squared and Y-direction hydrodynamic pressure squared. Hydrodynamic pressure under unidirectional horizontal seismic action in X or Y direction is obtained by square root of the sum of impulsive pressure squared and convective pressure squared. The results show that convective hydrodynamic pressure cannot be ignored when the tank is subjected to seismic action. The relationship between the sloshing wave height and hydrodynamic pressure is determined, the hydrodynamic pressure components and their combination are verified, calculation methods for hydrodynamic pressure are developed, and their distribution laws are presented.

The innovation is to reveal the hydrodynamic pressure law of ground-rested circular RC tanks under bi-directional horizontal seismic action. The research object is the ground-rested circular RC tank.
