The purpose of this advice is to provide guidance for NZ design professionals when using NLRHA to validate the seismic performance of structures.
The guideline draws upon knowledge that has been gained since NZS 1170.5:2004 was developed and sets out a contemporary approach for establishing earthquake design actions in structures when using NLRHA.
The guideline provides:
Recommendations for the selection and scaling of ground motion records,
Recommendations for modelling structural elements
Detailed criteria for evaluating seismic performance, and
Guidance for determining horizontal design actions for parts of structures and non-structural components.
