In fact, when the temperature load increase to 250 degrees. Reaction at point B is larger than at point A too. I can't figure out the theory behind it.
I set up a 2D analysis to study the effect of thermal load on 2D frame.
Case 1 - with short column and 10 degree of uniform temperature
Case 2 - with long column and 10 degree of uniform temperature
My question is, why for case 1 horizontal reaction at point B is larger than point A?
I did...
