hello guys,
i was going through TANK software report and found that it calculated annular plate thickness = 12.7mm
i have calculated the annular thickness myself stresses product and hydrostatic stresses comes out to be 191 and 192.7 MPa respectively . As per table 5.1a i think the required...
hello guys
i was going through calculations report (TANK hexagon) for storage tank having small internal pressure and found some discrepancy.
Mw (overturning moment about the shell-to-bottom joint from horizontal plus vertical wind pressure) mentioned in formulas of F4.2 and 5.11.2.1 are...

Hello guys
i have a question regarding compression area.

My question is if we calculate area as per 5.10.5 then we should not be calculating it using F.5.1 am i right?
suppose i have self...
can somone please clarify about the impact energy values mentioned in ug-84 (Figure 84.1) . These average values are for longitudinal direction or transverse direction. ?
