Estimation of Thermal Crack Resistance for Mass Concrete Structures with Uncertain Material properties

摘要

This paper presents an analytical method to predict the probability of thermal cracking for mass concrete structures. This method takes into account variations in materials, such as differences in thermal or mechanical properties, or changes in environmental conditions, such as the ambient temperature. Variations in the thermal stresses for structures with uncertain material properties were approximated using data from a sensitivity analysis and the first-order approxima- tion theory based on Taylor expansion.
