01/22

Additions

Optional table of maximum degree of utilization added.
In the deformation checks, the corresponding combinations are also written down.

02/21

Addition

Reading of old positions optimized.

01/21

Eurocodes

Polish design code PN EN 1995: 2010 implemented with associated load standards.
Update for the English National Annex of the design code BS EN 1995:2019.
Germany and Austria: New traffic load category H implemented for roofs.
permanent removable loads for solar panels added.
Special permanent load with different safety factors for Italy implemnted.

Addition

New Undo / Redo functionality implemented.
Depending on the roof geometry, loads from flat and monopitch roofs are also taken into account.
Extended wind zones and directions for wind loads can be selected.

Correction

Remarks repositioned in the system and design menue tree.
Output and calling for linked programs optimized.

02/20

Addition

Load transfer for all rafter purlin types to gluelam girder D10+.
Alternative calculation with HTM+ if articulated purlin is selected as purlin type.
Spacing of connectors with text and sketch in output added.

01/20

Eurocodes

New design code ÖNORM B 1995-1-1:2019-06 implemented.

02/19

Eurocodes

New snow load standard ÖNORM B 1991-1-3:2018-12 implemented.
CIRCOLARE:2019 according to NTC:2018 added.

Correction

The output option Combination List is now saved in the item.
Raw densities for custom material are also applied in the case of multiple changes.

01/19

Addition
