Hi,

I did design for diameter 17.8 m & 24.5 m ht tank.If i run the analysis , the output shows

WARNING #169 (General Tank Data)
API-650 Paragraph 5.5.3 warns that for tanks
in excess of 75 ft in height, an elastic analysis
must be used to determine the annular plate thickness.

How i can solve this Error.. which software can we use for elastic analysis?

Thanks
