%X Seismic instrumentation in a building is used to accurately capture its response during an  earthquake. This is helpful for building owners in their post-earthquake decision-making process  as, according to the Performance-based Earthquake Engineering Framework, the response data  measured should lead to enhanced predictions of the event’s consequences for the building.  This instrumentation can be costly however, so it is useful to know the extent to which varying  levels of its implementation within a building affect the accuracy of these predictions. The  purpose of this study is to develop a methodology for quantifying the errors in damage and loss  consequence predictions from the FEMA P-58 Seismic Performance Assessment procedure,  when different numbers of building instruments are used to capture the response of a building in  a given event. We use responses measured on an instrumented building during the 1994  Northridge earthquake, and obtain consequence predictions via Performance-based Earthquake  Engineering analyses using the FEMA P-58 methodology. The density of instrumentation  examined ranges from the case in which all floors are instrumented to that in which no  instrumentation is present and FEMA P-58 simplified procedures are used to predict response  and corresponding consequences.
