The existing nonlinear response history analysis (NLRHA) provisions in NZS 1170.5 were developed 20 years ago and significant developments in the selection and scaling of ground motion records have occurred since this standard was originally drafted. As a consequence the NLRHA provisions in NZS 1170.5 are out of date. To help address this issue, the collaborating technical societies of NZSEE, SESOC and NZGS are developing guidelines which can be used by 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 was published and sets out a contemporary approach for establishing earthquake design actions in structures when using NLRHA.
