I want to introduce Buckling Analysis based on ASME SEC. VIII Div.2 by using ANSYS.

Refer to attached pdf file.  

1. For Thermal analysis:

    - Steady state during Holding time was considered.

    - Two different conditions of convection loads are considered (Case-1 and Case-2).

2. For Structural analysis:

   - Half model was used (symmetrical BC applied)

   - 100% of Empty Weight is considered conservatively, applied on the Shell-Top Head junction.

3. For Evaluation:

   - Linear Buckling analysis in ASME Sec.VIII Div.2 Code (Par.5.4.1.3) was used.

   - Required Buckling Factor for cylinder under axial compression: 2.84
