# Computational Modelling of Concrete Structures Proceedings of the Conference on Computational Modelling of Concrete and Concrete Structures (EURO-C 2018), February 26 - March 1, 2018, Bad Hofgastein, Austria

The EURO-C conference series (Split 1984, Zell am See 1990, Innsbruck 1994, Badgastein 1998, St. Johann im Pongau 2003, Mayrhofen 2006, Schladming 2010, St. Anton am Arlberg 2014, and Bad Hofgastein 2018) brings together researchers and practising engineers concerned with theoretical, algorithmic and validation aspects associated with computational simulations of concrete and concrete structures. **Computational Modelling of Concrete Structures **reviews and discusses research advancements and the applicability and robustness of methods and models for reliable analysis of complex concrete, reinforced concrete and pre-stressed concrete structures in engineering practice.

The contributions cover both computational mechanics and computational modelling aspects of the analysis and design of concrete and concrete structures:

- Multi-scale cement and concrete research: experiments and modelling
- Aging concrete: from very early ages to decades-long durability
- Advances in material modelling of plain concrete
- Analysis of reinforced concrete structures
