Seismic Loads for Liquid Containing Rectangular RC Tank According ACI
This sheet provides Seismic Loads for Liquid Containing Rectangular RC Tank According ACI.
Liquid storage tanks generally possess lower energy-dissipating capacity
than conventional buildings. During lateral seismic excitation, tanks are
subjected to hydrodynamic forces. These two aspects are recognized by most
seismic codes on liquid storage tanks and, accordingly, provisions specify
higher seismic forces than buildings and require modeling of hydrodynamic
forces in analysis. In this paper, provisions of ten seismic codes on tanks are
reviewed and compared. This review has revealed that there are significant
differences among these codes on design seismic forces for various types of
tanks. Reasons for these differences are critically examined and the need for a
unified approach for seismic design of tanks is highlighted.
