for SEISMIC DESIGN OF

for seismic design of tanks,there are many limitations in the provisions of IS 1893:1984,some of which have been discussed by Jain and Medhekar (1993,1994).Thus,one finds that at present in India there is no proper Code/Standard for seismic design of liquid storage tanks.In[DOC]12 - American Petroleum Institute flat bottom tanks seismic use group iii#0183;Web viewPredicted global tilt,measured in inches,of a flat bottom tank shell should be limited to 5 times the tank diameter divided by the height.iii) Differential Center-to-Edge Settlement Liquefied gas tanks are constructed with self supporting roofs.Differential settlement between theWelded Carbon Steel Tanks for Water Storageiii Committee Personnel The Standards Committee on Steel Elevated Tanks,Standpipes,and Reservoirs,which reviewed and approved this standard,had
