  • For the DBN V.2.6-98:2009 standards, the option to output the safety factor for the specified reinforcement as an envelope result for each check has been added.
  • For the DBN V.2.6-98:2009 standards, the option to determine the strength safety factor for precise reinforcement pattern in PR types has been added.

Within the Wall reinforcement type, it is possible to perform analysis of walls and pylons with a detailed arrangement of all rebars and selection of zones of corner reinforcement and reinforcement along edge.

An alternative method is implemented for determining reserve factors for types of pilot reinforcement at a fixed value of axial force.

Added option to define additional number of intermediate reinforcing items for increasing reinforcement. This option is available for the following list of element types: bar, column, beam.

New option to define any number of horizontal cuts of transverse reinforcement to check the types of pilot reinforcement. For the exact type of PR, there is an option to create several layers of transverse reinforcement.

For the check of load-bearing capacity, the user could define an exact location of the reinforcement bars without grouping them into zones as is done for a complete analysis, e.g. with account of torsion.

New option to create and edit names of custom materials: concrete and reinforcement.
