This paper presents the methods of practical analysis of the thermal stresses. The analysis of there stresses is usually very complicated, as the axial ds formations of members must be considered in addition to the bending deformations. The author dev〓k method for practical purposes by use of stiffnesses of members and other assumptions. One of the characteristic points of this method is the definition of stiffness coefficient of column (column stiffness), which has the same meaning to the lateral force distribution coefficient for the seismic analysis. In case of thermal stresses, however, the distribution coefficient itself cannot be applied because of the different tendency of frame deformation. The author changed, therefore, the definition of column stiffness to fit it to the case of thermal stresses and succeeded in the simplification of equations with sufficient accuracy. Two methods are presented in this paper; one is comparatively accurate method, and the other is the modified method for rapid estimation of thermal stresses. Examples are added to illustrate how to compute, and limitations for the use of both methods are also discussed.
