Analytical investigations on out-of-round shell deformation of cylindrical tanks are also presented.This experimental program was the second phase of a research project in which various scaled tank models were tested to assess the applicability of current seismic design practice to ground supported,thin-shell,cylindrical liquid storage tanks.Seismic analysis and design of liquid storage structures I am working on the seismic analysis and design of partially buried / ground-supported liquid storage tanks and I am looking for some guidance regarding the analysis and design approach. ASCE 7-05,Section 15.7.6 covers ground-supported storage tanks and provides equations for calculation of base shear (also considering hydrodynamic forces)Seismic Vulnerability Assessment of Liquid Storage Tanks Liquid-filled tanks are effective storage infrastructure for water,oil,and liquefied natural gas (LNG).Many such large-scale tanks are located in regions with high seismicity.Therefore,very frequently base isolation technology has to be adopted to reduce the dynamic distress of storage tanks,preventing the structure from typical modes of failure,such as elephant-foot buckling,diamond

Seismic Response of Liquid Storage Ground Supported Tanks

Seismic responses - base shears,the bending and overturning moments - are calculated by using the response spectra of the earthquake in Loma Prieta,California (18.10.1989).As the examples is analyzed the ground supported cylindrical concrete tanks,fluid filling is H = 2 m and R are depended from tank slenderness ratio = H/R.Seismic Response of Liquid Storage Ground Supported Tanks Seismic responses - base shears,the bending and overturning moments - are calculated by using the response spectra of the earthquake in Loma Prieta,California (18.10.1989).As the examples is analyzed the ground supported cylindrical concrete tanks,fluid filling is H = 2 m and R are depended from tank slenderness ratio = H/R.Seismic Isolation of Cylindrical Liquid Storage Tanks [3] Veletsos,A.S.Seismic effects in flexible liquid storage tanks,in Proceedings of the 5th World Conference on Earthquake Engineering; Vol.1,1974,Pages 630-639.Google Scholar [4]
