Stability design now also for N=0.
If there is only 1 horizontal support on a roof side, it can be used for connections, even if it is not the last support of the rafter.

Correction

When a position was saved, there could occure an error 53.
Calculation of kv due to DIN NA NCI 6.5.2 was changed, because this applies only for top notching.

02/16

Eurocodes

Glulam according to EN 14080:2013 implemented for Germany and Italy.
The "old" Glulam timbers are marked with * (for example GL24c*).

Addition

Output Profile:

The load combination list is set for the output as default.

Correction

Snow loads for ÖNORM EN: If the influence area is smaler than 10 m² then the snow load is increased.
The behavior of snow accumulation has been corrected in the load dialog.
Additional snow load was set to domestic load when transfered to DLT.
Corrected factor kh to increase strength with small cross-sections.
D12: The selectable but not changeable number of the collar beams is removed.

01/16

Eurocodes

Correction

D9: Wind loads corrected for uplift design of mono-pitch rafters.
DGK: Values for width and height are stored in the load dialog again.

01/15

Addition

Implementation of DIN EN 1995:2013 in combination with EN 1995:2014.
Preset design standard can be defined in the project properties.

Correction

Averaged kmod for wind loads according to German NA.
D9: Option for automatic dead loads can be saved.
D11: Query for item calculation when entering the connection dialog without results from rafter.
D12: Correction of asymmetric base connection.
DGK: Comment for the designed cross section in the output. Default cut out depth = 50 mm.

02/14A

Correction

User-definded windloads will be shown correctly after reopen of loads-dialog.
Snow-accumulations in DGK were shown two times in graphics. This item is corrected.
Combinations mit wind as additional loads corrected.

02/14

Improvement

Graphics: Overlapping of support-numbers prevented.

Correction

Programm will start with the last used code.
Input of length of roof will be accepted in input field.
Userdefined windloads will be shown after reopening of the dialog correctly.
Numbers of supports synchronized between graphics and text.

01/14

Corrections

The calculation of fcalphad has been corrected and the coefficient kcr is considered in the proof of notchings.
The calculation of the wind lenght e has been improved for gablesided wind for the proof against liftoff.
Now the maximum internal forces are used for the proofs of the footing details instead of the maximum support reactions.

support reactions by design situations

The max/min support reactions are now seperated by the design situations.

EN 1995 Italy

UNI EN 1995-1-1/NA:2007 and UNI EN 1995-1-1/NTC:2008 implemented.

02/13B

Corrections

Crash with supports of hip/valley-rafters has been corrected.
Support reactions of the program DGK are always shown in [kN].
Crash with joints of collar beams for single collarbeams has been corrected.
Proofs for plausibility in thermal proofs have been improved.
ASCII-Interface and the converting from D2 to D9 have been improved.
The desciption of the snow reference length at jack rafters has been improved.

02/13A

Exceptional snow loads

Exceptional snow loads are now equal treated as usual exceptional and accidental loads.
Therefore the exceptional snow load is no longer considered for proofs in case of fire.

DGK

Now it is optionally possible to consider singelsided alternative windpressure loads for the main- and gableroof.

02/13

The undergrate wind blast for "wind from right side" in D9 has been corrected in case of user defined windloads.
Internal modifications for libraries.

01/13C

Improvement of translations
Corrections for proofs in case of fire for double-sided collar beams.

01/13B

Corrections

Importing old D6-positions with DIN 1052:1988 into DGK makes the load values to big by the factor of 10000. Now it is corrected.
When importing old positions with DIN 1052:1988, now the coefficients due to humidity for resistance and E-Moduli are set to the values according code.

01/13A

The manual for DGK has been added.

01/13

New

With the new module DGK it is possible to do analysis and design of hip and valley rafters.
