Research Topics
We are developing numerical analysis models that integrate multi-scale (space: μm to km, time: milliseconds to several decades) and multi-physics (combined problems of mechanics, physics, and chemistry) phenomena, aiming to establish various performance evaluation methods for concrete structures that take into account the material-structure linkage and the time axis from both analytical and experimental perspectives.
Using the 3D-RBSM (Rigid Body Spring Model), a discrete mechanical analysis that is being developed independently in our laboratory, we are elucidating various phenomena involving cracks in concrete.
We are also taking on new challenges in many other fields, so please feel free to contact us!

We conduct research using discrete analysis and structural experiments with the goal of providing society with rational and safe concrete structures. In order to increase safety against excessive forces such as earthquakes, we are clarifying the fracture mechanism and considering the use of new materials such as fiber reinforced concrete. We are also conducting research that will lead to improved productivity and performance by innovating structural details that have been considered tacit knowledge. On the other hand, to prevent safety from decreasing due to aging, we are evaluating the performance of concrete structures that deteriorate due to time-dependent deterioration such as rebar corrosion, and inspection, diagnosis, repair and reinforcement methods. As a result, inspection and diagnosis methods using laser technologies and electromagnetic radar, which were developed through collaborative research with companies and research institutes, are being implemented in society.
If you would like to contribute to society by constructing and maintaining concrete structures, which are major infrastructure facilities, please contact us.

Taito Miura
Using discrete analysis and microstructural analysis, we evaluate the internal swelling reaction of cement-based materials and their behavior in severe environments in the nm to mm range. By mutually evaluating the relationship between meso-level cracks and cement hydrates below the microscale, we are conducting research to elucidate phenomena in which mechanical, physical, and chemical phenomena are intricately intertwined, discover phenomena that have not been visualized until now, and develop new living spaces such as the deep sea.
In addition to these research projects, we are also conducting international collaborative research with France and the UK, so if you are interested in mechanism-based research linking materials and mechanics and expanding overseas, please contact us.
