Background and objective: Seismic risk management which convert earthquake damages to amounts of damages, providing proper estimation of existing risk conditions while provides appropriate strategies to reduce damages for the decision-making sector, whether employer of a specific project or urban planners At macro level. In this paper, the application of seismic earthquake engineering with seismic reliability approach as a tool for facilitating decision making in risk management of investment in construction sector in seismic cities has been studied.
Method: the seismic performance of a 12-storey steel office building considered as a case study by using seismic reliability analysis; three risk management strategies including reduction, transfer and integration of reduction and transfer seismic risk in order to reduce possible losses in the lifetime of building utilization and investment preservation has been studied. Therefore, the confidence index of providing the level of immune function in the probable earthquakes over the lifetime of the building in question is defined as a common indicator between the decision making and decision maker department of the project and the effect of the improvement of this index from 49% In the design model, an 80% regulatory code has been used to assess the risk of damage to the building investor in the application of risk management strategies.
Findings: In the surveyed building, subject to the requirement of an 80% confidence level, in order to meet the expected performance targets of the structure, according to the seismic regulations of the country (vital security), the risk level of the employer's capital is dropped between 2% and 20% for the different levels of possible damages. Simultaneous use of both risks of reduction and transfer strategies has also contributed to reducing the probability of a risk to the loss of capital by 5 to 20 percent at different levels of damage and helped to reduce the suspension period in the economic activity of the building at the time of the possible earthquake.
Results: The study results show that the quantitative index of the confidence level of performance objective supply, help to facilitate decision making for both employer and policy makers in construction sector in order to apply the risk management strategies for reducing damages and capital protection in construction sector.
Keywords: Reliability, seismic risk management, performance-based earthquake engineering, loss, earthquake insurance
