Popis: Rapid assessment of the resilience and vulnerability of critical structures and infrastructures is necessary to prepare stakeholders and decision-makers for risk mitigation during future catastrophic events. The current study developed a web-based software tool called a Resilience indicator (Ri) that can estimate the seismic resilience index of Iranian structures. Ri can calculate seismic resilience index and draw functionality, IDA (Incremental Dynamic Analysis), fragility, and vulnerability curves. The approach includes rapid evaluation of the resilience index using vulnerability curves as well as accurate evaluation of structural resilience through uploading the results of nonlinear dynamic analysis to the Ri software. The current version of the software can be applied by civil engineers, stakeholders, and decision-makers. Meanwhile, the on-going development of the software aims to expand its capabilities in the area of seismic risk assessment. Compared to other similar tools, Ri is able to demonstrate the performance of structures right after the occurrence of an earthquake until the considered control time. Having utilized a strong database of more than 300 existing fragility and vulnerability curves, Ri will clearly show the vulnerability of structures by which the functionality curve can be attained as well.
