The lecture focusses on two procedures for performance-based seismic design of bridges, each following one of the previously described approaches.
In the first one, the ‘direct displacement based design approach’, pioneered by Priestley and Kowalsky and involving elastic analysis and over-damped elastic spectra, is extended with a view to making it applicable to a broad spectrum of bridge systems, including those affected by higher modes, and also introducing additional design criteria not previously used in this method.
The second method involves more advanced analysis tools, i.e. response-history analysis (for different levels of ground motion intensity) of bridge models wherein any regions that are expected to yield under the selected seismic actions are modelled as inelastic, whereas the rest of the bridge is modelled as elastic; the initial analysis (relevant to service conditions) is an elastic one.
