About public announcements such as earthquake-resistant diagnosis results of building obliged to carry out earthquake-resistant diagnosis

Last update date July 28, 2020

Based on "law (1995 law No. 123) about promotion of earthquake-resistant repair of building", we announce contents of result of earthquake proofing diagnosis and order for unreported person about building obliged to carry out report of conduct of earthquake-resistant diagnosis and the result.

1.Target building

(1) Emergency security confirmation large-scale construction thing required
 Large-scale thing which construction started with buildings that needing used the unspecified number of people and in evacuation particularly consideration on before May 31, 1981

"Scale requirements of large-scale building obliged to carry out earthquake-resistant diagnosis" (PDF: 68KB)

(2) Security confirmation plan mention building required
 Things (※ 2) constant height that construction started with building facing particularly important road (※ 1) which should secure traffic at the time of earthquake disaster before May 31, 1981 or more

(※ 1) "Should secure traffic among roads particularly important road at the time of earthquake disaster" (PDF: 740KB)
(※ 2) "... with constant height or more things" (PDF: 22KB)

2.Public announcement contents

  • Name, position, use of building, road name (limited to security confirmation plan mention building required.)
  • Safe evaluation result for earthquake of part main in structure proof stress with name of method of earthquake-resistant diagnosis and the building concerned
  • When have plan of earthquake-resistant repair, rebuilding or removing, the contents and effective time

3.About evaluation of earthquake-resistant diagnosis

Evaluated safe evaluation division becomes I - III of list shown below by earthquake-resistant diagnosis.

Safe evaluation for earthquake of part main in structure proof stress
IWe collapse for vibration of earthquake and shock or are at increased risk for collapsingQuake resistance is short
IIThere is the risk collapses for vibration of earthquake and shock or to collapse
IIIIt is at low risk of we collapse for vibration of earthquake and shock or collapsingQuake resistance is secured

 We evaluate the risk earthquake-resistant diagnosis collapses for around seven large-scale earthquake vibration from intensity 6 upper or to collapse.
There is little fear that the damage occurs unless thing and deterioration built illegally are left things, and, for earthquake vibration that is scale out of one of intensity 5 upper degree, as for the fear to collapse, there are none.

4.Public announcement of result of earthquake-resistant diagnosis

 (when change occurred in equal public announcement contents when quake resistance is secured by earthquake-resistant repair, we update at any time.)
(1) Emergency security confirmation large-scale construction thing required

(2) Security confirmation plan mention building required

※About safe evaluation for earthquake every building, we can confirm by safe evaluation (PDF: 75KB) and above "list of earthquake proofing diagnosis results" for earthquake of main part in evaluation and structure proof stress of appended chart earthquake proofing diagnosis according to earthquake-resistant confirmation method (PDF: 345KB).

5.Report order of earthquake-resistant diagnosis result

 As we ordered based on regulations of law Article 8 Paragraph 1 for person who does not report result of earthquake-resistant diagnosis, we announce the contents based on regulations of article Paragraph 2.

6.Support to facility where quake resistance is short
