To our knowledge, no single building has experienced three successive strong ground motions from major earthquakes that occurred nearby. In Turkey this happened in a roundabout way when three identical buildings designed to serve as the provincial directorate offices for the Ministry of Public Works and Resettlement (MPWR) underwent such an experience over a time span of 11 years in three different cities that were hit by major earthquakes. The provincial offices are designed and constructed according to template designs under the Ministry's own supervision. For ease of access and security, the Ministry's strong motion recording stations that are part of the national network are located adjacent to these buildings. This study examines the performance of three of these standard ground-plus-four-story reinforced concrete (RC) frame buildings that were subjected to strong ground motions in different cities of Turkey. Bidirectional nonlinear dynamic analyses of 3D analytical models are performed. The principal focus of these nonlinear analyses is to assess whether the analytical model of the buildings could indicate column-beam damage consistent with that observed at the sites after the earthquakes. Our results illustrate that nonlinear time history analyses are capable of indicating the occurrence of shear failure in captive columns, but they overestimate the global damage level for all buildings.
