摘要: Airports are one of the critical infrastructures that play an essential role in managing natural disasters through receiving or sending aid and supplies. Air traffic control (ATC) towers inseparable part each airport as performance airports depends on functionality their ATC towers. Many have been designed constructed based older versions modern seismic codes which design has followed a force-based approach. This study addresses vulnerability three in-service according to concept. The height ranges from 24 52 m. Fragility curves used for these For derivation fragility curves, 45 earthquake records were selected classified into low, medium high classes ratio peak ground acceleration (PGA) velocity (PGV). It was observed with low PGA/PGV imposed highest level damage However, when subjected ratio, intensity not significant. Results indicated seismic-induced tallest tower significantly more than shortest tower. concluded only could satisfy expected objectives.
