HAZARD ASSESSMENT OF DUBAI, UNITED ARAB EMIRATES, FOR CLOSE AND DISTANT EARTHQUAKES

摘要

The paper presents an earthquake hazard study for Dubai, United Arab Emirates (UAE). The seismicity of the area is outlined and discussed in terms of available earthquake data and published earthquake catalogues. Strong motion estimation models are also discussed and a specific model is selected and extended to meet the defined requirements for the study. The hazard assessment is carried out to evaluate peak ground acceleration and uniform hazard response spectra corresponding to 5% and 2% probability of being exceeded in 50 years. Simulated earthquake ground acceleration records are derived for the purposes of dynamic response history analysis. The implications of the hazard from near and far earthquakes is explored with regard to the dynamic response of tall buildings and other long-period structures common in the study area.
