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)

Performance-based earthquake engineering Design for the achievement of specified results rather than adherence to prescribed means. (after May 2004) This mission is derived from Helmut’s version, but is shortened to fit in two lines of normal font text.
