Please note that i had modelling steam pipeline and Input parameters for high pressure steam pipeline are as below :
Design Code = ASME B31.1
Fluid = High Pressure Steam Pipe Size (Main Steam Header) = 219.1 mm
Design Thickness (Main Steam Header) = 23.01 mm
Pipe Size (Smaller Pipe – Limb) = 88.9 mm
Pipe Thickness (Smaller Pipe – Limb) = 11.13 mm
Design Pressure = 14366 KPa
Hydro Pressure = 21550 KPa
Design Temperature = 545°C
Mill Tolerance = 12.5%
Pipe Density = 0.00764 Kg/cm3
Fluid Density = 0.00004 Kg/cm3
Pipe Material = SA335 P91 (Alloy Steel)
Insulation Thickness = 100 mm
Insulation Density = Mineral Wool (0.00014)
Stress analysis performed at following load cases :
HYDRAULIC
OPERATING
SUSTAIN
EXPANSION
Now i have to analyse this model with WIND & SEISMIC load cases.
Please guide me brief steps for doing WIND & SEISMIC load cases.
Thanks in advance.

You need to seek guidance from your Lead Stress Engineer.
IMHO, this is a forum, not an educational website.

Dear,
You must define your load cases
properly as per project requirements
. See attachment "Load Case Definition in CAESAR II" for quick reference.
As mentioned, this is just a guide, and your lead stress engeneer will solve any doubt you could have.
Regards.
