CEOS.fr Project Presentation
The overall objective of the CEOS.fr project is to take a significant step towards improving the engineering capabilities for assessing concrete structure crack patterns and predicting the patterns expected under anticipated design conditions. The CEOS.fr program includes three work areas that are relevant for the control of cracking monotonic loads, thermo‐hydro‐mechanical (THM), seismic and cyclic loads. Digital image correlation (DIC) was specifically used to measure crack widths on the whole surface of the test specimens. The resultant DIC surface measurements were correlated with internal measurements of the temperature evolution inside the specimen blocks overall and local strain evolution and rebar stress. Cracks were detected by the measurement system strain gauges, linear variable differential transformer (LVDT) and fiber sensors. The probabilistic scale effect can be simulated by using the Weibull theory, and the weak value of the tensile strength can be mainly explained by the use of a simplified approach based on this theory.
