ROBOT Millennium v. 20.1 Maintenance Pack 3

1.    Structure calculations

• Enhancements in selection of overlapping lines
• Correction of descriptions of structure axes

• Preserving a ”frozen” FE mesh if meshes are adjusted automatically
• Corrections concerning loads:
  • verification of loads on contours,
  • possibilities to force displacements for partial elastic supports.
•  Supplements to steel section databases (GOST and RPOL).
• Correction of generation of elastic linear supports for shells.

Calculations:

• Correction in calculations for supports with friction.
• Enhancements in calculations of buckling in the non-linear analysis by means of the BFGS method.
• Correction in calculations for a non-linear support defined at the “master” node of a rigid link.

Results:

• Removal of a fatal error on opening a table of bars and deflections for RC sections.
• Unblocked calculation notes if the “My documents” folder is moved to the root.

Remaining issues:

• Correction of work of selected methods of ”com” interface (ROS):
  • unneeded deletion of supports when modifying object geometry,
  • correct information about the list of objects of a given story.

2. RC Calculations

General:

• Preserving data while copying ”Inspector” elements.
• Taking account of a change of a level name in drawings.

Slab calculations:

• Acceleration of reinforcement generation and correction of map display.

Beam calculations:

• BAEL91 code:  corrections of generation of ‘bielles’.

Column calculations:

• ACI code: correction of capacity surfaces for seismic combinations.
• BAEL91 code: correction of fire resistance calculations for slender columns.

Spread footing calculations:

• ACI, BS, CSA, EC7:  correction of values of stress in the soil for bi-directional bending.

3.    Steel Calculations

Steel member design:

• ASD: increased value of admissible stresses is correctly taken into account.
• EC3:  correction of bending verification for large transversal forces
• AIJ-ASD, BS 5950:2000, BSK99, GB50017-2003, NS 3472:2001, SNIP II-23-81, STAS10108/0-78: Correction of an incorrect buckling length in calculations of groups.

Connection design:

• Removal of a fatal error on opening a project with connections defined according to different codes.
• CM66:  
  •  correction of resistance of the beam-beam connection
  • removal of a fatal error of calculations and indefinite partial results,
  • correction of verification of anchor lengths for a fixed column base.
• Generation of a fixed column base in the place of a fixed elastic support.

Remaining issues:

• Timber column design according to CB71 – correction of fire resistance calculations for rotated sections.
