A STUDY ON THE EARTHQUAKE RISKS ASSOCIATED WITH THE AUTOMOTIVE INDUSTRY IN THE MARMARA REGION
(Thesis Supervisor: Eser Durukal)
This study ia carried out to evaluate earthquake vulnerability of the automotive facilities located in the Marmara Relgion. The importance of the automotive industry in Turkey and role of the Marmara Relgion in the earthquake hazard was discussed. the part of the automotive industry in the Marmara Relgion in the Turkish Economy is explained on the basis of statistics about the unit production and export data. The earthquake exposure of the automotive manufacturing plants in the Marmara Relgion was studied on the basis of probabilistic and deterministic approaches. The Marmara Relgion was suffered a significant earthquake in 1999. earthquake damages in the facilities were researched from the past reconnaissance reports, facility archives and interviews with the employees. With the support of Automotive Industry Association, eleven automotive manufacturing facilities located in the Marmara Relgion were visited. During these visits, questionnaire forms prepared to investigate the structural properties, non-structural aquipment details and auxiliary units (power, supplier, etc.) were used. After the site investigations, meetings were held by the constructor firms and insurance professionals to realize the retrofitting designs for the damaged facilities and the loss claims after the 1999 earthquake, respectively. On the other hand, earthquake hazard in automotive industry and the vulnerability of some specific machinery issues were interviewed with the reinsurance and risk management firms and machinery and robot manufacturing firms located in all over the world, by mails and phone calls. Composition of all these observations and data that found in this study will be a guide for the civil engineers who will design additional structures or will erect machinery and aquipments to the current automotive manufacturing plants, for the farsighted facility authorities who want to reduce the future damages due to earthquakes and the risk professionals of insurance or reinsurance firms who assess the earthquake risk of these or similar facilities.
