Design Engineering Laboratory
To maintain social infrastructure facilities, it is necessary to establish a rational design method that effectively utilizes the properties of materials such as steel and concrete and efficiently combines their structural elements. Accordingly, it is crucial to elucidate the static and dynamic mechanical properties of structures. In this field of education, to acquire basic skills in structural engineering, earthquake resistance engineering, and structural design engineering, students will learn the static and dynamic behavior of structures, as well as their evaluation methods, via basic theory and experiments. Regarding the research, we are conducting theoretical and experimental studies with the objective of establishing protective design methods for structures that are exposed to impact loads, such as explosion and collision loads.

Research on the impact resistance of reinforced concrete
We are currently studying the reinforcing effect of short-fiber reinforced concrete and its mechanism.
Research on the impact-resistant design method for steel members
We are currently studying the impact behavior and fracture mechanism of steel materials.
Research on the protective design of the structures subjected to explosion
Research on the nature of blast pressure and the destruction of structures
We are currently studying the intensity, distribution, and temporal characteristics of blast pressure, as well as the mechanism of the destruction of structures by blast waves.
We are currently studying the characteristics of earth pressure, blast waves spouting out of the ground, and vibrations, when an explosion occurs underground.
Research on explosion-load buffer system
We attempt to develop an explosion buffer system.
Collection of technical data
We collect technical data on the impact resistance of metals, fibers, resins, concrete, etc.
