An introduction to performance-based seismic design using advanced software packages

Performance-based seismic design (PBSD) can be applied to the design of any structure, regardless of its importance. Nevertheless, this article will mainly be of interest to structural engineers designing new buildings or working on retrofit interventions to high-profile projects falling outside the range of applicability of prescriptive procedures for seismic design of buildings contained in standards such as ASCE 7 and the International Building Code (IBC). In particular, the article will be of interest to engineers involved in the seismic design of buildings where specific performance-in-use expectations are set by the client. It is assumed that readers of the article have a good understanding of non-linear structural mechanics, earthquake engineering and structural dynamics.

The aim of this article is to help structural engineers follow the paradigm shift in seismic engineering from the definition of prescriptive procedures to procedures based on achieving predictable performance levels. The shift will be from the overall load-reduction approach, on which the experience of many structural engineers is based, to the damage-versus-deformation approach, reflected in current approaches to PBSD.
