The expected seismic performance of existing buildings during future earthquakes is always a concern for public administrations in pre- and post-earthquake planning as well as for general public. Seismic risk of these buildings, whether they will fulfill different performance-based design objectives when subjected to earthquake ground motions of different intensities, has to be evaluated. Such an evaluation for an existing building requires an accurate finite element model of the building. This study focuses on the first instrumented building in Turkey, for which the ambient and forced vibration test results are available to validate its finite element model. This reinforced concrete building is in close proximity to the North Anatolian Fault in Gerede, Bolu. Having survived the 1999 Mw 7.1 Duzce earthquake, the building was retrofitted in 2009 after the implementation of the 2007 Turkish Earthquake Code. The finite element models that incorporate the infill walls were developed for both the as-built and post-refrofit states of the building, and updated to reproduce the in-situ dynamic properties. Using these models, seismic risk assessments for both states of the building were performed according to the past and current building codes in Turkey. The demonstrated inadequate performance of the as-built building verified the need for the retrofit of the building. However, the post-retrofit building did not satisfy the performance objectives stated in the current building codes
