Benchmark on the cracking simulation of reinforced concrete ties

Abstract

International audienceThis contribution presents a part of the benchmark that was launched during the first year of the French na-tional project CEOS.FR. It consists in modeling the behavior of reinforced concrete ties and in simulating the evolution of the crack opening during loading. Different approaches are compared. The global mechani-cal behavior is generally well reproduced whereas the simulation of the crack evolution gives encouraging results (appropriate order of magnitude) but needs to be improve
