The structures subjected to the following loads/actions are concerned by the research group: (1) earthquake loads; (2) long period cyclic loads; (3)  environmental impacts. The structures include RC structures, steel-concrete composite structures containing high-performance or eco-materials such as HPC, ultra-high-strength steel, volcanic ash concrete, etc. 

On the other hand, the demountable structures also are being concerned in the group.

Research methods/equipment:

Structural quasi-static test;

FEM/DEM simulation;

Multi-physic fracture mechanics (phase field models, continuum damage models)

DIC analysis;

AI tech. for Civil Eng. (Deep Learning in Computational Mechanics)
