Abstract
In 11th March 2011, Great East Japan Earthquake that has Mw 9.0 attacked to East Japan, and it caused serious damage not only to human but also to industrial facilities and so on. In addition, lifelines, such as water, electric power and so on were broken and the quake-hit area was wide. Therefore the disaster had a harmful influence on the Japanese industry. In order to investigate factors of the seismic damage of mechanical structure and improve preparedness for the future earthquakes, The Japan Society of Mechanical Engineers (JSME) has set up an investigation committee. According to the investigation, the cause of damage is categorized into the strong ground motion, soil deformation and tsunami. The examples of damage caused by strong motion are deformation of braces of steel buildings, failure of tanks and deformation of pipe supports. The examples of damage caused by strong motion are deformation of braces of steel buildings, failure of tanks and deformation of pipe supports. The soil deformation by subsidence and liquefaction caused damage of anchor bolts and sinking of warehouses. The tsunami attacked to tanks, resulting in failure and slide. This paper describes the seismic damages of industrial facilities by the 2011 Great East Japan Earthquake.
