Sectіon C10 – Secondary and Non-structural elements

The Seismic Assessment of Existing Buildings (the Guidelines) provides a technical basis for engineers to carry out seismic assessments of existing buildings within New Zealand.

Part C of the Guidelines describes the Detailed Seismic Assessment (DSA) process used to assess the seismic behaviour of a building. This is a more comprehensive assessment than the Initial Seismic Assessment process described in Part B. The DSA assesses the structural load paths within the building, the capacity of each structural element, the likely inelastic mechanisms, the global building response to earthquake shaking and the impact of secondary structural and critical non-structural building elements.

The DSA process is based on the Part A principles, which are an integral part of the seismic assessment process. Sections C1, C2, C3 and C4 provide an overview of the DSA process, the assessment procedures and analysis techniques, the earthquake demands and geotechnical considerations. Sections C5 to C9 provide recommendations for specific materials and Section C10 provides recommendations for secondary structural and non-structural elements. Each of these build on the common aspects within Sections C1 to C4 and Part A.

Summary and Download

Section C10 (download) gives specific recommendations for assessing secondary structural and non-structural building elements. The guidance in this section allows these elements be scored either independently or in conjunction with an overall building assessment.

Many existing buildings have elements and components of different construction materials that work together to provide resistance to seismic shaking. The material sections (C5 to C9) use the same approach to establishing element and component capacities to allow all capacities to be integrated, after making due allowance for deformation compatibility issues.

The recommendations within this section should be used in conjunction with those in Sections C1 to C4 and Part A.
