Abstract: Thermal- and autogenous deformations are the primary causes of self-induced stresses in hardening concrete structures. Both types of deformations, and their interactions, are discussed and illustrated with examples from tests on different concrete compositions subjected to isothermal and realistic temperature developments.
For practical calculations of cracking risk in concrete structures, mathematical models for both types of deformations are needed. A strategy to develop such models is presented.
