In this paper, the auther studies on fire damages caused by thermal stresses at reinforced concrete frames and steel frames. It is assumed that the heating condition for the reinforced concrete beams is corresponding to the second class heating of JIS A 1304 and steel beams are heated at 300℃. The thermal stresses at the columns of the both sides of heated beams and at heated beams, in both cases, are much more over than the calculated stresses of these members by usual method.
