Establishing the Performance Point
•No building can be
pushed to eternity without failure.
•Performance point is
where the Seismic Capacity and the Seismic
Demand curves meet.
•if it exists, it may
be established by
–The Explicit R Factor
Method (Reinhorn and others)
–The Displacement
Coefficient Method (FEMA-273)
–The Capacity Spectrum
Method (ATC-40)
•If the performance
point exists and damage state at that point is
acceptable, we have a building that satisfies the
push-over criterion.
•If not, we
have to fix the building.
