After the Parameters field, specify the fragility parameters for each curve. Each curve should have a pair of parameters and the keyword for the fields are the words Median and Beta followed by a number that specifies which curve the parameter belongs to. Number should start at zero so if we have 2 fragility curves, the following 4 additional fields would be in the file:
Median0, Beta0, Median1, Beta1, Median2, Beta2, Median3, Beta3
Example CSV File
Below is a sample CSV fragility for a bridge. The first row is column names, the second row is column types (reserved for later use, but currently just ignored) and the 3rd row is a set of 4 fragility curves for an MSC_Concrete bridge.
