Recent progress on data-driven concrete material-structure integrated design
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.
