RE: Temperature load in STAAD (Thermal load of steel )

You have to know three temperatures :

1) the stress-free temperature, which is the temperature that the beam was at when it was constructed or installed. Call it A.

2) The temperature of the top fiber (the fiber that is farthest along the positive direction of the local Y axis). Call it B.

3) The temperature of the bottom fiber (the fiber that is farthest along the negative direction of the local Y axis). Call it C.


When you specify the temperature load, the command is


member-list TEMPERATURE f1 f2

where

f1 = (B+C)/2 - A

f2 = B-C
