Results envelope in Wingraf from multiple cdb's

is it possible to make an envelope of results (e.g. by comparing) for load cases from multiple databases?

it will be great future, e.g. in composite steel-concrete bridges. If linear analysis is assumed, calculations must be performed twice: in uncracked and in cracked condition. such model is generally built using CSM module, which already causes some overlap with load case numbers. Performing calculations for two databases seems to be the most convenient way, but there is a problem with simple display of envelopes from both databases.

best regards, sb

  • Generate both cdb:s
  • Copy the desired loadcases from one to the other using dbmerg. (shift lc-numbers if needed)
  • Use maxima to generate an envelope (or just use the max/min views in wingraf)
