New health assessment of structures and buildings - Measurement of strain tensor
Keywords: strain tensor, structure, tunnel, rock mass, concrete
Japan is located on a plate boundary, which results in a very high frequency of earthquakes globally, and consequently, there is a significant amount of damage to buildings. When an earthquake occurs, you may feel the "shaking." Earthquakes generate waves, causing the ground to shake and move in a repetitive manner. During this time, structures such as buildings and elevated structures experience complex movements, making it extremely difficult to accurately assess the internal deformations of these structures. Our research group has developed a technique to capture the detailed deformation (strain tensor) of small cylindrical rock samples with natural sedimentary structures in order to investigate the deformation of bedrock in detail, thereby improving accuracy. This method can be applied to buildings as long as the application points are creatively designed, regardless of the shape. In the future, we aim to utilize this technique for assessing the health of buildings and concrete structures during complex deformations, such as those occurring during earthquakes.
