Simple Procedure for Seismic Analysis of Liquid-Storage Tanks

Simple Procedure for Seismic Analysis of Liquid-Storage Tanks This paper provides the theoretical background of a simplified seismic design procedure for cylindrical ground-supported tanks. The procedure takes into account impulsive and convective (sloshing) actions of the liquid in flexible steel or concrete tanks fixed to rigid foundations. Seismic responses - base shear, overturning moment, and sloshing wave height - are calculated by using the site response spectra and performing a few simple calculations. An example is presented to illustrate the procedure, and a comparison is made with the detailed modal analysis procedure. The simplified procedure has been adopted in Eurocode 8. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Structural Engineering International Taylor & Francis
