CIS/2 Interface

Import and Export of CIS/2 Files

GT STRUDL includes a bi-directional CIS/2 analysis model data interface to Smart 3D. Engineers can take advantage of the extensive modeling features of Smart 3D and the powerful structural analysis and design capabilities of GT STRUDL. Other programs that use the CIS/2 model data format can also be interfaced to GT STRUDL.

Import of CIS/2 Files

GT STRUDL can read the following information from a CIS/2 analysis model data file:
  • Joint/node location
  • Joint/node support condition and release status
  • Member (beam element) incidences
  • Member profile and cardinal point
  • Member beta angle
  • Member end releases (pinned connections)
  • Member eccentricities
  • Load cases
  • Applied joint loads
  • Applied member loads (concentrated/distributed, local/global) Load combinations
  • “Assembly maps” – Which analytical members compose a single physical member

Export CIS/2 Files

GT STRUDL can create a CIS/2 analysis model data file containing all the data listed for import, plus analysis results:

  • Support reactions
  • Joint/node displacements
  • Member end forces

When exporting a CIS/2 analysis model, the user can select:

  • Units (length and force)
  • Whether to include applied loads or results
  • Default steel grade
  • Assumed member type (beam, column, or brace)
  • Convert from a global Y-vertical axis to a Z-vertical axis
  • Write analysis elements as physical elements
