Bridge objects which have a large number of post-tensioned [tendons|kb:Tendon] may be modeled more efficiently by either using [interactive database editing|kb:Interactive database editing] or by [importing|kb:Import] a spreadsheet which lists tendon data. Manual entry of tendon data may be unnecessarily time-consuming.

Spreadsheet importapplication is also useful when tendon profile is described by a set of parameters which differs from that used by [CSiBridge|csibridge:home]. Given such a case, users should first convert tendon definition from the customized format to the format consistent with CSiBridge. Converted data may then be imported.

h1. Importing tendon data

These tables, shown in Figure 1, may be exported to Excel using the Orb > Export > Excel option. Tendon data may then be modified in Excel, and imported back to CSiBridge using the Orb > Import > Excel option.


h1. Entering tendon data through interactive database editing

Alternatively, users may edit tendons directly by using the interactive-database-editing feature, available through Advanced > Edit > More > Interactive Database Editing.
