Resumo

This paper presents recent advances in numerical modeling of massive concrete structures resulting
from the conclusions of the Technical Committees of RILEM TC 254-CMS "Thermal cracking of massive
concrete structures" and RILEM TC 287-CCS ‘‘Early-age and long-term crack width analysis in RC structures’’,
committees chaired by the authors. The TC 254-CMS Committee met for 7 years (2013-2019) and involved the
participation of approximately 30 researchers and professionals from different continents. In addition to several
meetings, symposia and participation in Conferences, the Committee has published a book on the state-of-the-art
and also some articles in specialized journals that indicate procedures pertinent to the construction of massive
structures that are of fundamental importance for designers and constructors. Therefore, in the present paper,
several conclusions about the best practices in numerical modeling of the problems related to the hydration of
early-age concrete will be addressed. The concept of massivity index will also be discussed which determines the
need to analyse a structure considering the hydration effects at the early ages.
