Structural expertise

CESAR is equipped with standard features for structural analysis: beams and shell elements, springs and other links, various types of loads, static and dynamic analysis algorithms….

CESAR proposes several constitutive models dedicated to the modelling of concrete (parabolic criterion, Willam-Warnke…) or masonry (homogenization of Zucchini…). In particular, damage models are integrated for the evaluation of durability of structures: Mazars, Faria, Oliver…

In addition, CESAR is suited to analyse the concrete behaviour in service or ultimate conditions. Specific modules, named TEXO & MEXO, have also been developed to enable modelling of the early age concrete behaviour. TEXO serves to compute both the temperature and degree of hydration fields, used to express the material’s state of hardening. These results are then input in the MEXO module in order to determine the displacement and stress fields, in the aim of predicting the risk of cracking at early age.

As such, CESAR can contribute to the understanding of the overall behaviour of a project and to the expertise of failure mechanisms.
