Abstract
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.
