Seismic analysis For Pure Conical Elevated Tanks Including Fluid Structure Interaction

Abstract

A study on the seismic response of pure conical tank was conducted. Finite element method was used to investigate the seismic response of pure conical tanks. Three dimensional models using SAP 2000 V 15.1.0 analyses software were used to simulate the studied tanks. Seismic response of conical tank is different from cylindrical tanks due to the vertical resultant of the hydrodynamic pressure in conical tanks, accordingly in order to represent fluid structure interaction, added mass approach was utilized using mechanical analog developed by El Damatty and Sweedan (2006). A comparison of the seismic response of pure conical tanks between the finite element model results, American Water Works Association- D100 (2005), and Egyptian code-201 (ECP-201-2012) was performed.
