Thanks for your reply
I've gone through the technical manual but I couldn't find any definition for the STRESS or STRENGTH envelopes.
The SERVICEABILITY and COLUMN envelopes are a little bit clear but I failed to understand the difference between the STRESS and STRENGTH envelopes.
I will appreciate it if you give me a clear explanation.
