GB/T 37267-2018 General specification of seismic bracing for building 1 Scope This standard specifies the general requirements, requirements, test methods, inspection rules, marking, packaging, transportation, and storage of the seismic bracing for buildings. This standard is applicable to the design, manufacturing, and inspection of seismic bracings for systems such as the building water supply and drainage systems, heating, ventilation, and air conditioning systems, electrical systems, gas systems, and fire protection systems in areas with seismic fortification intensity of 6 to 9 degrees. 2 Normative references The following referenced documents are indispensable for the application of this document.
