Yokohama City has established three types of seismic diagnosis methods used for seismic retrofitting design of wooden houses. For businesses registered in the design category, the availability of each seismic diagnosis method is described. The characteristics of each seismic diagnosis method are as follows.

[Precision diagnosis type] ・・ ・ It is possible to accurately grasp the current situation and carry out appropriate reinforcement work according to the actual situation.

[General diagnosis type] ・・ ・ Although the burden of the survey is small, the effect of suppressing construction costs is low because the estimated value is used.

[Wall volume satisfactory type] ・・ ・ We can carry out the minimum necessary reinforcement work to reduce the amount of money and prevent collapse.

※[Precision diagnosis type] [General diagnosis type] [Wall volume satisfactory type] The name of Yokohama was originally defined by the City of Yokohama.
