Engineering library update - May 2022

The latest Tekla Tedds engineering library update is available in Tekla Downloads.

Note: This update was re-issued on May 26th 2022 as version 24.02.0001 to include fix TEDDS-6767.

American Design

Retaining wall analysis & design (ACI318/TMS/MSJC)

Significantly enhanced calculation including the following new features and improvements:

  • Include the restoring effect of surcharge loading in the stability calculations.

  • Specify custom load combinations which allow the analysis part of the calculation to be used for other design codes.

  • Include or exclude active pressures on the key in the stability calculations.

  • Include or exclude passive pressures of the soil in the stability calculations.

  • View the analysis model from within the user interface to provide transparency on how the analysis model is set up.

  • Specify, or have calculated, a user-defined seismic force so that input forces can be entered directly from a geotechnical report.

  • Option to allow a fully grouted CMU wall with reinforcement at different spacing, so you can comply with the seismic requirement for a fully grouted wall and have the flexibility to vary the reinforcement spacing.

  • Option to specify the soil bearing pressure as net or gross so either value specified in a geotechnical report can be used.


Product bulletin April 2022 (PBT-2205-1)

Wood shear wall design (NDS) - Fixed a potentially un-conservative error affecting the design of a shear wall using Sheathing on gypsum, any thickness, 10d nails with 4in panel edge nail spacing. For more detailed information please refer to Product bulletin May 2022 (PBT-2205-01).

Australian Design

Retaining wall analysis & design (AS4678/AS3600/AS3700)

Significantly enhanced calculation including the following new features and improvements:

  • View the analysis model from within the user interface to provide transparency on how the analysis model is set up.

  • Include the restoring effect of surcharge loading in the stability calculations.

  • Specify custom load combinations which allow the analysis part of the calculation to be used for other design codes.

  • Include or exclude active pressures on the key in the stability calculations.

  • Include or exclude passive pressures of the soil in the stability calculations.


Canadian Design

Product bulletin April 2022 (PBT-2204-4)

RC beam design (CSA-A23.3) - Fixed an error in calculating the resistance factor for beams that require compression reinforcement. For more detailed information please refer to Product bulletin April 2022 (PBT-2204-04).

Eurocode Design

Retaining wall analysis & design (EN1992/EN1996/EN1997)

Significantly enhanced calculation including the following new features and improvements:

  • Include the restoring effect of surcharge loading in the stability calculations.

  • Specify custom load combinations which allow the analysis part of the calculation to be used for other design codes.

  • Include or exclude active pressures on the key in the stability calculations.

  • Include or exclude passive pressures of the soil in the stability calculations.

  • View the analysis model from within the user interface to provide transparency on how the analysis model is set up.

  • Option to specify mesh reinforcement in the stem and base rather than just loose bar reinforcement.

  • Added an additional check for a masonry reinforced wall to check the shear resistance of the concrete alone if the masonry shear check fails.

  • Added the shear enhancement in Annex J for masonry retaining walls so that a wall has a greater chance of passing the shear check (not applicable for the Finland national annex).


Product Bulletin April 2022 (PBT-2204-3)

RC column design (EN1992) and Precast concrete column design (EN1992) - Fixed a potentially un-conservative error affecting the calculation of the moment capacity for circular sections with concrete class less than C50/60. For more detailed information please refer to Product bulletin April 2022 (PBT-2204-03).

Other updates

Steel beam torsion design (EN1993)
TEDDS-6619 Fixed overall design status in output.
Retaining wall analysis & design (EN1992/EN1996/EN1997)
TEDDS-6767 Fixed an error where the transverse reinforcement couldn't be changed in the user interface.
