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 A of the Guidelines outlines the scope and application, and provides a general overview of the seismic assessment process. It describes the linkage with the relevant requirements of the Building Act 2004, associated regulations and the EPB methodology. It also provides a brief overview and outline of the key principles of reducing the seismic risk of buildings – designing seismic ‘improvement’.
Part B of the Guidelines sets out the Initial Seismic Assessment (ISA), which provides a broad indication of the likely level of seismic performance of a building. potentially earthquake-prone buildings in some circumstances.
