About publication such as earthquake-resistant diagnosis results of building where earthquake-resistant diagnosis was required

Based on the "Law Concerning the Promotion of Seismic Retrofitting of Buildings (Act No. 123 of 1995)" For buildings that are required to conduct seismic diagnosis and report the results, For those who have not yet reported We publish the contents of order.

（１） Emergency safety confirmation Large-scale buildings
　Buildings used by an unspecified number of people and those who need special consideration in evacuation, large-scale buildings that started construction before May 31, 1981

・"Scale requirements for large-scale buildings requiring earthquake-resistant diagnosis" (PDF: 68KB)

（２） Building with safety confirmation plan
　A building facing a particularly important road (* 1) that should be secured in the event of an earthquake disaster, and above a certain height that was started before May 31, 1981 (* 2)

（※１） "Especially important roads that should be secured during an earthquake disaster" (PDF: 740KB)
（※２） "What is more than a certain height ..." (PDF: 22KB)

• Name, location, use, road name of building (limited to buildings with safety confirmation plan required)
• Name of the method of seismic diagnosis and the evaluation result of the safety of major parts of the building against earthquakes in terms of structural strength
• If there is a plan for seismic retrofitting, rebuilding or removal, the content and timing of implementation

The safety evaluation categories evaluated by the seismic diagnosis are I to III in the table below.

　The seismic diagnosis evaluates the risk of collapse or collapse due to a large-scale seismic motion with a seismic intensity of 6 to 7 or more.
For medium-scale seismic motions with a seismic intensity of about 5 or more, there is little risk of damage and there is little risk of collapse unless it is illegally constructed or degraded.

　(If there is a change in the published content, such as when earthquake resistance is secured due to seismic retrofitting, etc., it will be updated as needed.)

• Subsidiary system
  We assist for earthquake-resistant repair design, earthquake-resistant repair work and removal work and support approach of earthquake resistance. For more information, please refer to the following website.
  • Condominium earthquake resistance support project
  • Assistance projects such as seismic retrofitting of specific buildings
• Seismic total support business (limited to buildings listed in the safety confirmation plan)
  For buildings whose seismic diagnosis has been completed, a person with specialized knowledge and experience will visit the building owner so that the design and construction can be started systematically in the future. I will do it. For more information, please refer to the following website.
