Dear Abhi,


Will you elaborate; which type of structure you are designing?
In plate modeling you have to be very careful about the orientation of plate model.
It will be always better to have static check to validate your model.
After analyzing the section you will get the stress contour which will help you to design your section.
You can also design the plates using the moment values from STAAD which has to be converted in to Wood-Armer moments for the further design.

hi,
For yogendra rathi
well i will try my best to elaborate this reformer structure. basically it is a vertically circular stack like reformer.i am attaching a JPEG pic with this mail.more over the loads of refractory is applied on plates as element load and wind load is also applied on plates as wind pressure in X and Z direction(-/+ ) both direction.
Now as per API this type of structure plates should be checked for longitudinal stress, membrane stress and bending stress.combined longitudinal and bending check is also be done.
can u explain in details how to design the plates using the moment values from STAAD which has to be converted in to Wood-Armer moments for the further design??

For Kunal,
kunal u said that the stresses are in KN/sqm/m but when i checked it in post processing it shows in KN/sqm.
and in technical reference it says that stresses are in force/unit length/thk. this means it is KN/m/m. can u explain it...in detail.
and moment is in force X length/length which means KN.m/m should be the unit.
please clearify.
with regards,
abhi
