C2 – Assessment Procedures and Analysis Techniques

Assessment
Part C sets out a methodology for engineers to conduct a Detailed Seismic Assessment (DSA) to assess the structural load paths of the building, the capacities of the structural elements, the likely inelastic mechanisms, the global building response to earthquake shaking and the earthquake rating for the building.

A limited revision of Section C2 has been undertaken. The motivation for this revision was to correct inconsistencies with updated versions of Section C5: Concrete Buildings. Errors identified in Version 1 have also been corrected, and updated references provided.

This document should NOT be used for an assessment that a territorial authority will use to decide is a building is earthquake-prone. Seismic Assessment Guidelines for potentially earthquake-prone buildings can be found on MBIE’s website.
