Behavior of seismic isolation device during excessively large earthquakes
This study deals with behavior of seismic isolation device during excessively large earthquakes such as nonlinear behavior of rubber bearings.
Seismic assesment focused on energy
This study develops a seismic assesment method using energy that can evaluate cumulative damage by earthquakes.
R&D of Tuned Mass Damper for excavators
In Japan, excavators are used for demolitions of buildings, and cause ground vibration duaring operation. Therefore we research and develop a Tuned Mass Damper to reduce uncomfortable vibration induced by excavators
Soundness assesment of wire rope using image processing
This study develops system using image processing that can measures diameter of wire ropes.
R&D of health monitoring system for pipe
Pipes in a factory or a chemical plant may be damaged by erosion and corrosion as a result of a long term operation, and these damages induce stops of operation or other severe damages. This study develops a system that detects damages inside pipes by processing vibration measured during operation.
