As a result of the unexpectedly poor performance a comprehensive study has been initiated to assess and rehabilitate existing school buildings in many parts of the country. A special emphasis was given to the buildings located in İstanbul due to the perceived high probability of a severe earthquake there. Within this framework, a large number of school buildings in İstanbul have been selected for detailed assessment to determine whether there is a need for their rehabilitation to improve their performance. The study under the World Bank program ISMEP has been directed by a unit under the Governorship of İstanbul. Each school building was thoroughly surveyed to obtain its as-built structural layout, member sizes, geometrical features and material properties. The assessment was based on the recently promulgated Turkish rehabilitation code that suggests linear as well as nonlinear procedures for the assessment and rehabilitation purposes. In addition to code specified seismic forces, site specific seismic hazard analyses were carried out considering an M7.2 earthquake occurring in the Marmara sea segment of North Anatolian Fault. This study presents the results of seismic assessment carried out for approximately 50 reinforced concrete school buildings. Details of the building statistics containing their material quality, structural and architectural features are provided. All of the schools were investigated using linear analysis procedure whereas three selected schools were also assessed using nonlinear procedures based on pushover analysis. Due to lack of adequate calibration and validation of the procedures the code recommendations were found to be too conservative in the linear and nonlinear analyses.
