Seismic Hoop combined Stress Calculation for Shell Course:

Impulsive Hoop Membrane Force per E.6.1.4-2b [Ni]:
= (2.77 * Ai * G * D^2)
* ((Y / D * 0.75) - (0.5 (Y / D * 0.75)^2))
= (2.77 * 0.375 * 1.100 * 49.213^2)
* ((6.562 / 49.213 * 0.75) - (0.5 (6.562 / 49.213 * 0.75)^2))
= 448.234 lb. [1993.744 N.]

Convective Hoop Membrane Force per E.6.1.4-4b [Nc]:
= cosh ( 3.68 ( H - Y ) / D )
/ cosh ( 3.68 * H / D )
* 0.98 * Ac * G * D^2
= cosh ( 3.68 ( 72.178 - 6.562 ) / 49.213 )
/ cosh ( 3.68 * 72.178 / 49.213 )
* 0.98 * 0.093 * 1.100 * 49.213^2
= 148.879 lb. [662.214 N.]

Product Hydrostatic Membrane Force [Nh]:
= 0.0361 * G * Y * 12.0 * D * 12.0 / 2.0
= 0.0361 * 1.100 * 6.562 * 12.0 * 49.213 * 12.0 / 2.0
= 923.258 lb. [4106.653 N.]

Total Combined Hoop Stress per E.6.1.4-6:
= (sqrt( Ni^2 + Nc^2 + (AV * Nh)^2 ) + Nh) / Thk
= (sqrt( 0.000^2 + 0.000^2 + (0.168 * 0.000 )^2 ) + 0.000 ) / 0.197
= 7215.565 psi [49748.438 KPa]

please check the report

the values are not matching in this calculation
and the units are not matching as per API 650 STD

and please clarify TH Nh value calculation

when i had provide the anchor bolt dia in input - 42mm
but the generated out put report shows 82.0mm instead of 42mm

please clarify
