Abstract In seismic risk assessment, the fragility curves are commonly used to express the probability of exceedance of the predetermined damage states as the function of the earthquake ground motion parameter for structures. In this paper, the seismic vulnerability of single story precast reinforced concrete industrial buildings located in the organized industrial zones in Turkey were studied. The 273 existing buildings located in the different regions of Turkey were surveyed to get their geometry and structural parameters and 80 model types were identified. The effects of the structural parameters on the structural damage were studied via the fragility curves. The damage index parameter was used in the analytically obtained fragility curves for the four damage states as a function of spectral acceleration. Two sets of ground motion records were used representing the soft and stiff site conditions in the incremental dynamic analysis. The aim of this study is to obtain mean fragility curves for the three main classes of industrial precast reinforced concrete building structures, namely the Poor, Typical and the Superior. The structural parameters of stiffness, ductility and strength were used in the classification of the buildings. The study has focused on the probable maximum loss estimation for the above three building classes. The results indicate a good compatibility with the observed damages in the past earthquakes. It is believed that the proposed study can be used for seismic risk assessment based on the spectral acceleration levels experienced by these single story precast reinforced concrete industrial buildings.
Highlights The seismic vulnerability of the precast RC industrial buildings in Turkey was studied. The geometrical and structural parameters of 273 buildings were gathered from different regions of Turkey. The incremental dynamic analysis was carried out on 80 model types at two site conditions. Damage index parameter was considered and the fragility curves were obtained as a function of the spectral acceleration. The mean fragility curves were derived for the three main classes namely the Poor, Typical and Superior.
