NZS 1170.5:2004 PDF Download

NZS 1170.5:2004 is a standard that provides procedures for determining earthquake actions on structures in New Zealand. It covers various aspects of earthquake-resistant design, including verification procedures, site hazard determination, evaluation of structural characteristics, structural analysis, deformation limits, and seismic design. The standard is meant to be used in conjunction with other relevant parts of NZS 1170, which deal with different design actions.

The standard also includes appendices that provide guidance on aspects such as ultimate limit state design and the use of material-specific structural design standards in conjunction with NZS 1170.5. The purpose of this standard is to assist structural engineers in assessing and calculating the forces and deformations caused by earthquakes on structures, ensuring that they comply with the earthquake resistance requirements of the New Zealand Building Code.
