In recent years, the collective behavior of the elements and vital infrastructure of a society against unpredictable events has becamed very important. Responding to these incident events has never been easy, and so the having adequate resiliency is totally vital to mitigate the negative effects of these events on the infrastructure of society. Resilience is a new approach to earthquake engineering that includes organizational, technical, social, economic, and environmental issues. The goal of resilience is to minimize losses (economic and operational) to restore the community or system affected to pre-injury conditions (in some cases returning to better operating conditions than the initial state) in the shortest possible time.
Since proper planning and preparation for future earthquakes is necessary in disaster management, the development of a software programs has been on the agenda of engineers, stakeholders and politicians in recent years to estimate the vulnerability of critical infrastructure of communities. For accurately estimation of the vulnerability index and the resilience index of the structures, it is possible to take effective measures to reduce the seismic risk of vital arteries with tools such as strengthening, retrofitting and repairing them. Hence, in this thesis, for the first time, Ri (Resilience indicator) which is a software for calculating the seismic resilience index of critical structures and infrastructures throught our country, Iran, , has been developed and presented.
The software used to calculate the resiliency index, has been adopted the latest methods in the field of seismic resilience, fragility and vulnerability issues. Seismic Resilience index would be assessed by two different modes: a) use of prepared vulnerability curves; b) after performing IDA analysis, by uploading an Excel file containing the maximum inter story drift ratio and pseudo acceleration in fundamental period of structure, the resilience index would be evaluated finally. The software has been web-coded to allow the user to easily calculate the resilience index by specifying several parameters and entering their data according to the properties of the structure, the type of lateral load resisting frame, the year of construction , The structure height, the output of the nonlinear dynamics analysis of the structure and so on.
