摘　　要：材料-结构一体化设计是指在结构设计中综合考虑材料的性能,而在材料设计中则以结构的需求为出发点,形成材料到结构跨多尺度的设计模式,近年来已成为现代混凝土工程领域的研究重点。基于数据及人工智能算法的混凝土材料、结构设计方法可颠覆传统设计依赖经验且需重复试配的范式,实现高效节材及结构创新。梳理了国内外混凝土材料智能设计及材料-结构一体化设计的研究现状,总结了材料层面数据驱动的正向预测及逆向设计的研究范畴和关键问题,梳理了考虑温-湿-约束复杂交互的材料-结构一体化抗裂设计途径与效果,以氯盐侵蚀环境为例分析了混凝土材料-结构耐久性设计方案及提升手段,并以超高性能混凝土为例阐述了混凝土材料-结构高性能设计的方法,提出未来数据驱动的混凝土材料-结构一体化设计框架及生产、设计、制备及结构应用全综合的研究思路,并建议未来应在数据库建设、数据与理论融合及多尺度关联的协同算法等方面开展研究。Material-structure integrated design is to consider the material performance in structural design and to originate the material design from the requirements of the structure,forming a multi-scale design from materials to structures,which is a research focus in concrete constructions in recent years.The design of concrete materials and structures based on data and artificial intelligence algorithms subverts the traditional paradigm of relying on experience and requiring repeated trials,improving effeiciency in material design and structural innovation.This study reviewed the current research on the intelligent design of concrete materials and integrated design of material and structure.The research scope and key issues of data-driven properties prediction and design at the material level was summarized first.The strategies and effects of crack resistance material-structure integrated design considering complex interactions of temperature,humidity and constraint was discussed.The method for durability design and the improving measures using chloride diffusion as an example were described.The method of high-performance design using ultra-high performance concrete as an example was also explained.Finally,the framework for future data-driven material-structure integrated design as well as a comprehensive research concept including material production,design,preparation and structural application were proposed.The further studies should focus on database construction,knowledge-informed machine learning algorithms and multi-scale correlation.
