Engineering library update - May 2022
Tekla Tedds engineering library update (May 2022 - version 24.02) is available in Tekla Downloads.
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).
