Performance-Based Earthquake Engineering with Application to a Bridge Structure
Performance-based earthquake engineering (PBEE) is emerging as the next-generation design and
evaluation framework under which new and existing structures will be analyzed for seismic adequacy.
This webinar presents the application of the PBEE methodology developed at the Pacific Earthquake
Engineering Research (PEER) Center to the Humboldt Bay Middle Channel (HBMC) Bridge modeled and analyzed
as a nonlinear soil-foundation-structure interaction (SFSI) system. The HBMCB, with precast and
prestressed concrete I-girders and cast-in-place concrete slabs, is fairly representative of older
AASHTO-Caltrans girder bridges. It is supported on pie groups in soils potentially vulnerable to
liquefaction during an earthquake, which could induce lateral spreading and permanent soil deformations.
This webinar present the nonlinear finite element model of the bridge-foundation-ground (BFG) system
used and then focuses on the several analytical steps of the PEER PBEE methodology as applied to this bridge.
This methodology integrates in a probabilistic framework seismic hazard analysis, seismic demand analysis,
capacity analysis reliability/damage analysis and loss analysis. Several potential failure mechanisms of
the HMBC Bridge are considered: flexural failure of bridge piers, failure of shear key(s), and unseating.
Fore each failure mechanism, several limit/damage-states measuring the stage of formation of the mechanism
are defined. The seismic reliability against these limit-states is evaluated in terms of mean annual
rate/frequency of exceedance or, alternatively, return period. As outcome of the seismic loss analysis,
the seismic loss hazard curve expresses the mean annual frequency of exceeding any total annual seismic
repair/replacement cost. Selective results will be presented which illustrate the various steps of the
PEER PBEE methodology as applied to the HBMC Bridge.
This course will award 1.5 hours of continuing education.
The times will be 10:00 Pacific, 11:00 Mountain, 12:00 Central, and 1:00 Eastern
