Major Contributing Factors to Seismic Risk of Industrial Facilities
Experience of resent earthquakes such as Northridge- US (1994) or Izmit-Turkey (1999) earthquake have shown that industrial facilities are vulnerable to earthquakes and their associated economic loses are considerable. Noteworthy efforts have been made to reduce the amount of risk in these facilities in terms of public safety and environmental protection. Yet the risk of these facilities from economical point of view not fully studied. The main objective of this paper is to highlight the main contributing factors in the economic losses of these facilities which evaluated by the parametric study of a loss estimation model. The results have implication in risk management of industrial facilities. In this paper, first, a brief description of model is presented; then, effect of several influential parameters is quantified by conducting parameters study on the mathematical model. In this study, in addition to contributing parameters on direct losses, the effect of influential factors on secondary hazards and indirect loss has been studied. The results have shown that some unprecedented parameters such as dependency of factory to its household, financial condition of factory and speed of lifeline restoration have significant effect on the indirect loss of industrial facilities.
