Erfassung von Verformungs- und Spannungszuständen im jungen Beton infolge Temperatur
The young concrete is characterized by hygro-thermal effects as well as the development of the material properties and the relaxation of the restrained stress. The objective of this paper is to develop a strategy for the computation of stress due to temperature fields in young concrete construction elements, starting from the material behavior. The computation results were verified for the temperature with tests in the laboratory and in situ; for the stress the verification of the computation was accomplished by experiments in the laboratory. The influence of the concrete mix proportions and the construction technology on the temperature and stess was examined with example from a blast furnace foundation. Subsequently, the influence of the material fields on the cross section was evaluated. The paper contributes to the computational solution of thermal and mechnical problems of the young concrete.
