Timber member analysis & design (EN1995)
Timber 2D analysis & design (EN1995)

New Timber member analysis & design calculations which are fully integrated with the 2D analysis calculation. The calculations check the design of solid timber, flitch, glulam and LVL members subject to major axis bending, shear and axial tension or compression. The design checks are in accordance with EN1995 and the national annex for the UK, Ireland, Finland, Norway, Sweden or the recommended Eurocode values.
The 'Timber member analysis & design' calculation can be used to design a single member or the 'Timber 2D analysis & design' calculation can be used to model a small frame or truss and then design one or more members in that frame as required.

Timber member design (EN1995)

New version of the existing Timber member design calculation which checks the design of solid timber, flitch, glulam and LVL members subject to major axis bending, shear and axial tension or compression. Solid timber, glulam and LVL members can also be subject to minor axis bending. The design checks are in accordance with EN1995 and the national annex for the UK, Ireland, Finland, Norway, Sweden or the recommended Eurocode values.

Batch design

Enhanced to include the option to select an existing example and have the fields automatically populated. New working examples for Steel member design (EN1993), RC beam design (EN1992) and Timber member design (EN1995) are now included. A new option has been added to completely disable the user interface of a calculation if that calculation has a dedicated Calc API (Application Programming Interface), i.e. the calculation can be used to design check only with no manual user interaction. Refer to the calculation notes for specific calculations to determine whether they support a Calc API. If the user interface is completely disabled the calculation performance improves significantly, however the input data will not be validated in any way. An option has also been added to set the input variables in the user interface of the calculation to be read only thus preventing input which has been defined in the batch design work sheet from being subsequently amended in the user interface of the calculation.

Product bulletin August 2018 (PBT-1808-1)

[TEDDS-333]1 Retaining wall analysis & design (EN1992/EN1996/EN1997)- Fixed a potentially un-conservative error affecting the calculation of sliding and overturning checks in retaining walls with a depth of water behind them.
