DURABILITY SCALING OF HIGH PERFORMANCE CONCRETE (HPC) STRUCTURES USING THE PROBABILISTIC CRACK APPROACH

The paper summarizes some results of a combined experimental-theoretical research program on the durability of cooling towers with minimum reinforcement made of normal and high strength concrete, when subject to hygral and thermal gradients (Ulm et. al., 1998). The study confirmed that the structural durability performance is governed by the evaporable water content of the concrete. It scales both the magnitude and the time scale of drying, and thus the crack opening and its long term propagation.
