Abstract:
The next generation seismic design and assessment procedures for buildings within the performancebased
framework are a radical departure from traditional seismic design practice and performance assessment. The
uncertainty and randomness in the building performance and seismic hazard will be captured and quantified in each
steps in design and assessment procedure, finally the performance will be measured in terms of direct and indirect
economic losses and casualties. The quantification and propagation of uncertainty in every step in the procedure
requires robust probabilistic methods that have been developed over the last two decades. This paper summarises
the research undertaken to develop the probabilistic performance-based seismic design and assessment procedures
for buildings. The analysis methods, fragility functions and seismic hazard qualification, which are key elements in
procedures, are defined and discussed.
