Structural provisions

Article 38, which stipulates special materials and construction methods, was deleted by the 2000 revision of the Building Standard Law.
The "Technical Standard for Small and Medium-Sized Membrane Structural Buildings" and "Technical Standard for Specific Membrane Structural Buildings," which were previously approved under this article, are no longer in effect, and the treatment of membrane structural buildings under the Building Standard Law has changed. Membrane buildings must be designed in compliance with the following provisions of the current law.

Scope of application of the Ministry of Land, Infrastructure, Transport and Tourism Notification No. 666 of 2000

	framework-membrane structure		Suspension Membrane Structure Building
terms	Scale and shape other than those listed on the right	The area of the membrane surface enclosed by the framework is less than 300 square meters. Support pitch of membrane surface is less than 4 meters Roof shape: gable, single-slope, and arc roofs	No conditions
scale	Less than 1,000 square meters	unlimited	Less than 1,000 square meters

*Partial planning of movable membranes is now possible under the regulations. Please contact us for details.

*The above area restrictions can be relaxed for temporary buildings (e.g., for disasters, short-term entertainment, etc.), provided that they are removed during high winds.

*Scales and structures other than those listed above (e.g., air membranes) are outside the scope of application of the Notification.

Fire Prevention Regulations

Membrane buildings must also comply with the fire protection provisions of the Building Code.
Please use the Fire Prevention Regulations Checker for the application of membrane materials, etc.
Easily find membrane materials that comply with fire codes. For the membrane building you are trying to determine, please select the applicable details in order.
For more information, please feel free to contact us.

precautions

Basically, the judgment is based on fire prevention regulations only (structural regulations are not taken into account). (Structural provisions are not taken into consideration.)
No consideration is given to laws and regulations other than the Building Standard Law.
Establishment of Compliance Code (2006)
The results are indicated as "Membrane materials A to C" as the most legible indication, but there is no provision for such a name under the current law.
Tent warehouses and wooden buildings are not supported.

Checker for fire regulations for membrane buildings

A fire code checker is in preparation that will make it easy to find membrane materials that comply with fire codes.
Please feel free to contact us for more information on fire prevention regulations.

Material Regulations

Membrane materials used for membrane structural buildings must be materials approved by the Minister as "designated building materials" in accordance with Article 37, Item 2 of the Building Standard Law. (The quality standards for membrane materials are stipulated in the Ministry of Construction Notification No. 1446 of 2000, Appended Table 2, No. 18.) Membrane materials certified by the Minister are issued with a "Certificate of Approval" and a "Certificate of Designation" specifying the standard strength required for structural calculations. When designing a membrane building, please confirm the company name and content of these documents.

In accordance with the Ministry of Land, Infrastructure, Transport and Tourism Notification No. 666 of 2000, the membrane materials that can be used for membrane structural buildings are determined. Please be aware of this.
