ISO DIS 3010

Description / Abstract: This International Standard specifies principles of evaluating seismic actions for the seismic design of buildings (including both the super structure and foundation), and other structures. Certain structures such as bridges, dams, geotechnical works, tunnels, are beyond the scope of this Standard, even though some of the principles herein can be referred to for the seismic design of those structures.

The principles specified in this International Standard do not cover nuclear power plants, since these are dealt with separately in other International Standards.

In regions where the seismic hazard is low, methods of design for structural integrity may be used in lieu of methods based on a consideration of seismic actions.

This International Standard is not a legally binding and enforceable code. It can be viewed as a source document that is utilized in the development of codes of practice by the competent authority responsible for issuing structural design regulations.

NOTE 1 This International Standard has been prepared mainly for new engineered structures. The pr inciples are , how ever, applicable to developing appropr iate prescriptive rules for non-engineered structures. (See Annex N) The principles could also be applied to evaluating seismic actions on existing structures.

NOTE 2 Other structures include self-supporting structures other than buildings that carry gravity loads and ar e required to resist seis mic actions. These structures include seis mic force resisting systems similar to those in buildings, such as a trussed tow er or a pipe rack, or systems very different from those in buildings, such as a liquid storage tank or a chimney. Additional examples include structures found at chemical plants, mines, pow er plants, harbours, amusement parks, and civil infrastructure facilities.

NOTE 3 The level of seis mic hazard that w ould be considered low depends on not only the seis micity of the region but other factors, including types of construction, traditional practices, etc. Methods of des ign for structural integr ity includ e nominal design horizontal forces w hich provide a measure of protection against seismic actions.
