Deficiencies Summary

Deficiencies for Transition #1Transition calculations cannot be completed until a component is attached to the small end of the cone (or thediscontinuity is eliminated).The half apex angle is greater than 30 degrees. This results in UW-3 Category B weld joints being UW-12 type 8. Auser defined joint efficiency should be used.

Leg Calculations (AISC manual ninth edition)

Axial end load, P1 (Based on vessel total bending moment acting at leg attachment elevation)

P1 = W / N + 48*Mt / (N*D)= 1 277,11 / 4 + 48*0 / ( 4*28,125)= 319,28 lbf

Allowable axial compressive stress, Fa (AISC chapter E)

Cc = Sqr(2*π2*E / Fy)= Sqr(2*π2*29 000 000 / 36 000)= 126,0993

K*l / r = 1,2*35 / 1,1637 = 36,0909

Fa = 1 * (1 - (K*l / r)2 / (2*Cc2))*Fy / (5 / 3 + 3*(K*l / r) / (8*Cc)-(K*l / r)3 / (8*Cc

Allowable axial compression and bending (AISC chapter H)

F'ex = 1*12*π2*E / (23*(K*l / r)2)

F'ey = 1*12*π2*E / (23*(K*l / r)2)

= 1*12*π2*29 000 000 / (23*(36,0909)2)= 114 645 psi

fby= F*sin(α)*L / (Iy / Cy)= 0*sin(0)*35 / (3,02 / 1,75)= 0 psi

AISC equation H1-1

H1-1 = fa / Fa + Cmx*fbx / ((1 - fa / F'ex)*Fbx) + Cmy*fby / ((1 - fa / F'

AISC equation H1-2

H1-2 = fa / (0,6*1*Fy) + fbx / Fbx + fby / Fby= 143 / (0,6*1*36 000) + 0 / 23 760 + 0 / 23 760= 0,0066
