How can you use fragility curves to evaluate seismic performance?
Fragility curves are graphical tools that show the probability of structural damage or failure under different levels of seismic intensity. They are useful for evaluating the seismic performance of buildings, bridges, dams, and other structures, as well as for designing and implementing seismic retrofitting measures. In this article, you will learn how to use fragility curves to assess the seismic vulnerability and resilience of your structures.
-
Incremental Dynamic Analysis (IDA):By applying IDA, you can simulate how a structure will react to various earthquake intensities. This data creates a precise fragility curve, giving you insights into the building's resilience and helping inform safer designs.

Expert judgment:Leverage the experience of seasoned professionals to construct fragility curves when empirical data is scarce. Their insights can guide your seismic risk assessments and structural performance evaluations, ensuring informed decision-making despite data limitations.
