Zusammenfassung |
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. |
