Evaluation of Thermal Cracking Index in Slab-Concrete Under Uncertain Parameters

Abstract

In order to perform a highly reliable thermal stress analysis, it is important to consider analysis parameters as random variables which depend on materials in use, their mixture, environmental conditions, etc., and to evaluate their effects on thermal stress as well as on strength of concrete. Focusing on a slab-concrete, this paper investigates a sensitivity of thermal cracking index with respect to a variation of the parameters by using Monte Carlo simulation. Furthermore it is examined how a coefficient of variation of the parameters affects the relationship between a thermal cracking index and a probability of cracking.
