These recommendations have been prepared by the corresponding working group within RILEM TC 287-CCS “Early-age and long-term crack width analysis in RC structures”, following work by the previously ceased RILEM TC 254-CMS “Thermal cracking of massive concrete structures”. This recommendations document is developed in complementarity to the state-of-the-art report of RILEM TC 254-CMS and aims to provide expert advice and suggestions to engineers and scientists interested in modelling the thermo-chemo-mechanical behaviour of massive concrete structures since concrete casting. Recommendations regarding geometrical characteristics and complexities, concrete properties and appropriate material models, boundary conditions and loads, and numerical model peculiarities with relevance to the simulation of the thermo-chemo-mechanical behaviour of massive concrete structures are given herein. The recommendations have been reviewed and approved by all members of the TC 287-CCS.

这些建议是由 RILEM TC 287-CCS“RC 结构的早期和长期裂缝宽度分析”内的相应工作组在先前停止的 RILEM TC 254-CMS“大体积混凝土结构的热开裂”的工作之后制定的”。本推荐文件是对 RILEM TC 254-CMS 最新报告的补充，旨在为对大体积混凝土结构的热化学力学行为建模感兴趣的工程师和科学家提供专家意见和建议，因为混凝土浇筑。关于几何特征和复杂性、混凝土特性和合适的材料模型、边界条件和载荷的建议，本文给出了与模拟大体积混凝土结构的热化学力学行为相关的数值模型特性。这些建议已经过 TC 287-CCS 的所有成员的审查和批准。
