  • Evaluation and communication of seismic risk based on the long-term and short-term risk tolerance [Elektronski vir]
    Babič, Anže ; Dolšek, Matjaž
    An approach for the evaluation and communication of seismic risk is presented that is based on a five-grade grading system. Each of the grades (AA, A, B, C and D) indicates a level of long-term and ... short-term risk tolerance. Long-term risk tolerance is equivalent to the conventional concept of risk tolerance, while short-term risk tolerance corresponds to a specific period of time in which risk is allowed to be greater than in the long term. The grading process is performed in two steps. First, the initial grade is determined based on the comparison between the estimated risk and a set of risk boundaries. If the initial grade corresponds to long-term negligible or tolerable risk, the grading process is concluded. However, if risk is long-term intolerable, another step is performed, in which the initial grade is gradually reduced to the lowest grade (grade D). The time periods corresponding to the reduction of grades are determined by comparing the estimated cumulative risk to the cumulative risk boundaries. The grading system can be used for multiple purposes. As a communication tool, it can serve to enhance the public discussion about tolerable risk and to incorporate the aspect of seismic risk in self-regulating markets. However, it can also be used as the basis for disaster risk management by linking grades to specific sets of actions which are scheduled after the risk evaluation. The use of the grading system is demonstrated by performing a risk evaluation of a precast reinforced concrete building, which is exposed to long-term intolerable risk. It is shown that by using the grading system in risk evaluation, the period can be determined in which the owner is required to strengthen the building in order to avoid detrimental actions.
