EVALUATION OF THERMAL CRACK OCCURRENCE IN MASSIVE CONCRETE STRUCYURES

EVALUATION OF THERMAL CRACK OCCURRENCE IN MASSIVE CONCRETE STRUCYURES

Authors propose a probabilistic approach for the evaluation of thermal crack occurrences, which introduces thermal crack index, random variable defined in terms of the ratio of the concrete tensile strength to the thermally induced tensile stresses due to external restraints. Furthermore, this repor...

Zusammenfassung:Authors propose a probabilistic approach for the evaluation of thermal crack occurrences, which introduces thermal crack index, random variable defined in terms of the ratio of the concrete tensile strength to the thermally induced tensile stresses due to external restraints. Furthermore, this report discusses some factors affecting the thermal crack ocurrence probability. It becomes clean that the degree of external restraint, tensile strength and calculation method of thermal crack index are the most contributing factors.
