Doubt about the missing studs in the endurance surface material? <Concept in seismic isolation devices>

Is there a standard regarding the omission of intermediate columns in the Building Standards Act? I will report on the investigation regarding the omission of intermediate columns for seismic control devices, etc.

There are no regulations regarding the omission of studs in panel shear walls in the Building Standards Act, but caution is necessary when using panel products that have obtained ministerial certification, as there are specific regulations. To use a panel as a shear wall, it must be constructed with stud dimensions equal to or greater than those specified in the certification document; if it is less than the specified dimensions, it will be excluded from the wall strength calculation. If using the α Damper ExII, it can be installed without omitting studs due to its small size. [Example of required stud widths listed in the certification documents for each type of panel] ■ Novopan STP II: 60mm or more ■ Tiger EX Hyper: 105mm or more ■ Dailight: 45mm or more ■ Moiss: 50mm or more ■ Anshin: 60mm or more *For more details, please download the PDF or feel free to contact us.
