Steady-state stresses in concrete structures subjected to sustained and cyclically varying temperatures
The state of stress in non-uniformly heated concrete structures is significantly influenced by creep. When temperatures are sustained or vary in a cyclic manner over long periods, the long term state of stress may be deduced by direct calculation and without knowledge of the previous history of stress. The long-term stress states which correspond to cyclic variations of temperature are termed steady-state-cyclic stresses to distinguish them from the steady-state stresses which relate to sustained temperatures. Theory and numerical examples are presented and it is concluded that a power dissipation formulation of the theory is appropriate for general analyses for which compatibility criteria cannot be specified in advance. Stress redistribution is less severe under cyclic conditions of temperature than when temperatures are long sustained.
