1.0.1 This standard was formulated to implement the guideline on prevention first in seismic operation, lighten the seismic destructiveness of the prestressed concrete building structures after the seismic protection, avoid the casualties and reduce the economic loss.
1.0.2 This standard is applicable to the seismic design of such building structures as the cast-in-situ post-tensioned prestressed concrete frame and slab-column in the areas with seismic protection intensity of 6~8 magnitude; however, the seismic design of the prestressed concrete structures in the areas with seismic protection intensity of 9 magnitude shall be with full references and adopted with reliable measures.
1.0.3 The seismic design of the prestressed concrete building structure shall not only comply with this standard, but also shall comply with those specified in the current relevant national compulsory standards.
