American Design
Wood shear wall design (NDS)
Updated in accordance with the Special Design Provisions for Wind and Seismic 2021.
Retaining wall analysis & design (ACI318/TMS/MSJC)
Enhanced the calculation to include a Calc API so the calculation can be used in automation scenarios including the option to completely disable the user interface. The batch design has also been updated to include a Retaining wall stability analysis example.
Product bulletin October 2022 (PBT-2210-1)
Wind loading (ASCE7) - Fixed a potentially un-conservative error when determining the negative external parapet pressures of a monoslope roof pitch of less than 3 degrees when using the C&C method to ASCE7-16. For more detailed information please refer to Product bulletin October 2022 (PBT-2210-1).
Product bulletin September 2022 (PBT-2209-1)
Wood shear wall design (NDS) - Fixed a potentially un-conservative error affecting wood shear wall designs using a seismic deflection amplification factor other than 4. For more detailed information please refer to Product bulletin September 2022 (PBT-2209-1).
