ROBOT Millennium v. 18.0 Maintenance Pack 4

New options and possibilities:

Seismic calculations:

• Added possibility of seismic calculations according to Eurocode EC8 – Portuguese NAD

RC modules:

• New code DM 9/1/96 – implemented possibility of calculations of RC element reinforcement according to the Italian code DM 9/1/96;
• Provided (real) reinforcement of slabs – implemented possibility to define reinforcement of slabs with reinforcement in one layer and with unidirectional reinforcement;
• Spread footings:
  • presentation of bending moments acting on the spread footing
  • calculations of the required (theoretical) reinforcement before the punching reinforcement (?).

Steel connections

• New connection PN-90/B-03200 – fixed column base;
• New connection PN-90/B-03200 – concrete column base;
• Warning messages:
  • supplemented with display of numerical values of described quantities;
• Bolted connections:
  • added possibility of independent symmetrization of spacings and the whole arrangement of bolts.

Removed errors:

Calculation-related problems:

• Corrected error that resulted in blocking the calculations by means of the “Sparse” method for a structure involving moving loads;
• Corrected error of incorrect calculations of 3D structures (apparent e.g. in the imbalance of forces and reactions) occurring when supports rotated to the point are present.

Structure edition:

• Corrected errors of “Open GL” display that imposed deactivation of the graphic card acceleration;
• Restored work of the “previous selection” option.

Steel member design:

• Automatic buckling length for mixed structures – correction of the algorithm that imposes disregarding the shell part;
• PN-90/B-03200:
  • correction of the instability coefficient for asymmetric I-sections,
  • correction of the critical force value for the flexural-torsional buckling of C-sections.

Verification of steel connections:

• EC3 – fixed beam-column connection:
  correction of errors.

RC design:

• Beam reinforcement:
  • considered participation of axial forces in calculations of beam shear and cracking,
  • corrected optimization of diameters of the longitudinal reinforcement,
  • ACI: removed error of ignoring the compression reinforcement,
  • BAEL: corrected generation of triangular and open stirrups,
  • PN: removed error in evaluating the torsional and shear capacities;
• Spread footings:
  • corrected selection of the spread footing shape due to lifting,
  • PN: correction of diameters of transverse reinforcement.
