Seismic vulnerability assessment of school buildings in Tehran city based on AHP and GIS

Abstract. The objective of the current study is to evaluate the seismic vulnerability of school buildings in Tehran city based on the analytic hierarchy process (AHP) and geographical information system (GIS). To this end, the peak ground acceleration, slope, and soil liquefaction layers were utilized for developing a geotechnical map. Also, the construction materials of structures, age of construction, the quality, and the seismic resonance coefficient layers were defined as major factors affecting the structural vulnerability of school buildings. Then, the AHP method was applied to assess the priority rank and weight of criteria (layers) and alternatives (classes) of each criterion via pairwise comparison in all levels. Finally, the geotechnical and structural spatial layers were overlaid to develop the seismic vulnerability map of school buildings in Tehran. The results indicated that only in 72 (about 3%) out of 2125 school buildings of the study area will the destruction rate be very high and therefore their reconstruction should seriously be considered.
