[en] Nuclear power plants and other structures, when subjected to temperature variations and restrained against free movement, develop stresses. In some cases, members in a structure develop temperature stresses due to mutual restraint, i.e., interaction. In other cases, the affected members can be assumed to act independently of other members. Unlike gravity and some other loadings, for which the use of relative stiffness is adequate, dynamic and thermal loadings are directly related to the actual structural stiffness. A characteristic of thermal forces in concrete structures, unlike steel structures, is that these forces can tend to be self-limiting. High tensile stresses cause cracking of the concrete, and thus lower the temperature loads. Thus an iterative approach to the problem is generally called for. A method of analysis, based on the limit strength concept, is presented for concrete structures, subjected to temperature changes. This method shortens iterative efforts. The recommendations are general, and as such useful in thd case of members with uniform or non-uniform sections, and subjected to uniform or differential (different at two faces) temperature changes. The method is applicable in the case of frames, shells and other structures
