Building loss Modeling and Benchmarking EDP to
DV—1222003
James Beck (Caltech/F), Keith Porter (Caltech/O), Judith Mitrani (Caltech/GS)
Objectives: benchmarking and packaging
To evaluate the seismic performance of benchmark buildings designed to current
code (IBC 200x) in terms of PEER’s decision variables (DVs: repair costs,
fatalities, and repair duration, or “dollars, deaths, and downtime”)
and to package for practitioner use relationships between structural response
(PEER’s engineering demand parameters, or EDPs) and DVs.

Regulatory System Implications of Performance-Based
Regulation—1232003
Peter May (UW/Faculty), Chris Koski (UW/GS)
This research seeks to identify implementation issues that have arisen for other

Decision Making for Earthquake Mitigation—1252003
Jacqueline Meszaros (UW/F), Ufuk Ince (UW/F)
- Extend analytic decision model so that it is more comprehensive and
better fits users’ needs.
- Extend case study and survey work to yield
more complete understanding of how model may be made useful and other
matters that can affect PBEE adoption.
- Develop validity and reliability
data supporting the model.
- Analyze the closed claims associated with
the Nisqually earthquake in order to examine (insofar as possible)
how insured repair costs,
business interruption
losses, revenue losses and non-structural losses are associated with
some categories of soil conditions, construction type and building
ages.
