STAAD.Pro V8i SELECTseries 4 Release

I am excited to announce the latest new release of the STAAD.Pro V8i. This new SELECTseries 4 (version has published on the Bentley SELECT server and is now available for download.  The range of enhancements included addresses a wide range of aspects from analysis and design to improving facilities with section profiles.

Analysis and Design Engine

  • Steel Design per AISC 360-10 (*)
  • The design of steel sections per ANSI/AISC 360-10 Specification for Structural Steel Buildings (AISC 360-10) is now available in STAAD.Pro


  • Concrete Design per ACI 318-08 (*)
  • The design of concrete members per the ACI code in STAAD.Pro has been updated to the 2008 edition of the code.

  • IS 800:2007 Steel design (**)
  • The design of "star" angle arrangements per IS 800:2007 have been implemented in STAAD.Pro to for members subjected to axial force only. Angles in this arrangement are often used for the legs of transmission or communication towers and as bracing members in industrial buildings.

  • Eurocode 3 steel design, EN 1993-1-1:2005 (***)
  • The Eurocode 3 design EN1993-1-1 has been supplemented with the Malaysian National Annex “MS EN 1993-1-1:2005”.

Pre Processing

  • Center of Rigidity
  • The PRINT DIAPHRAGM CR command may be used to obtain a print-out of the center of rigidity and center of mass at each rigid diaphragm in the model.
  • Horizontal Torsion for Rigid Diaphragms
  • A new feature has been added to include horizontal torsion for rigid floor diaphragms in the equivalent static seismic analysis.
  • Check for Soft Story
  • The CHECK SOFT STORY option may added to a FLOOR DIAPHRAGM command set to check for soft stories per either IS1893:2002 or ASCE7-95 codes.
  • Check Story Drift
  • The PRINT SOFT DRIFT command can now be used to check the story drift against a code-specified maximum drift ratio.

General Developments

  • I-Section with Different Flange Shapes
  • User Provided steel table Wide Flange sections can now have different flange sizes on top and bottom. Previously, the sections were required to be doubly symmetric. Now, you can specify a different bottom flange size.
  • I-Section with Flange Plates or Composite Slab
  • User Provided steel table Wide Flange sections can now have an additional bottom flange plate or composite concrete on the top flange. The additional flange plates or composite slab data is then used along with the base section properties.
  • ISM Integration
  • STAAD.Pro is now capable of transferring data to and from v3 of Bentley's Integrated Structural Modeling technology by means of the StructLink utility.
