Overview
This page is intended to help users get their own bridge fragilities into MAEviz. The information you will find in this document is:
- File Types and Format
- Field Descriptions
File Types and Format
There are two acceptable formats, comma separated value (CSV) and Extensible Markup Language (XML). The simplest way to get fragilities into MAEviz is the CSV format which will internally be changed to XML. Both formats will be explained in their own section after the field descriptions.
Field Descriptions
Where there are a limited number of possible inputs, they will be specified in the Acceptable Values column in the table below or N/A for not applicable (e.g. author would be N/A). The informational column tells you if the attribute is for informational purposes or actually used internally by MAEviz. For example, the Code column is informational and simply tells the user if the fragility was intended as a retrofit and if so, what type. The fragility mapping is what will determine which fragility gets applied to which bridge. See the Fragility Mapping documentation for more about this topic.
