3. PEER Mission
Advance performance-based earthquake engineering to meet the needs of various stakeholders.
This mission is derived from Helmut’s version, but is shortened to fit in two lines of normal font text.
Main elements:
Develop and disseminate technology (as opposed to reducing risk)
Engineered systems
Regions of high seismic hazard
PBEE (that is, design to meet needs and objectives of owners and society)

5. Performance-based earthquake engineering
Design for the achievement of specified results rather than adherence to prescribed means.

6. Prescriptive design approach
Linear analysis model
Prescribed strength
Prescriptive details
The outcome:
performance an undefined byproduct of design
limited role for engineer O P E N
