Updates

2D analysis

[TEDDS-3552]1 - Removed references to Quasi combinations when the design code is steel or timber (requires Tedds 2020 SP2).
[TEDDS-545]1 - Enhanced for US sawn lumber and glulam material properties so that when selecting a material the density is automatically calculated.
[TEDDS-4791]1 - Updated the calculation of the Young's Modulus and the Shear Modulus to use the values from the source data which is appropriate to the selected NDS version.
[TEDDS-4795]1 - Updated default US timber model to use a dressed section which is the default option for the Wood member analysis & design (NDS) calculation.

Steel member design (EN1993) Steel member analysis & design (EN1993) Steel 2D analysis & design (EN1993)

[TEDDS-4751]1 - EN1993-1- 1 cl.6.3.3 uniform members in bending and axial compression were being incorrectly applied to members in tension.
[TEDDS-4761]1 - Fixed output not being created when user interface is disabled.

Timber member design (EN1995)

[TEDDS-4758]1 - Fixed output not being created when user interface is disabled.
[TSD-7560]1 - Hide national annex design option if setting is read only.

Seismic forces (ASCE7)

[TEDDS-4713]1 - Incorrect value of Fa used for site class D in summary output.

Steel member design (AISC360) Steel member design (AS4100)

[TEDDS-4761]1 - Fixed output not being created when user interface is disabled.

Wood member design (NDS) Wood member analysis & design (NDS) Wood 2D analysis & design (NDS)

[TEDDS-4789]1 - Corrected Young's modulus value used for analysis of Glulam using 2018 edition of NDS, so that Extrue is used rather than Ex.
[TEDDS-4758]1 - Output is not created when the user interface is disabled.
[TEDDS-4781]1 - Fixed when the wood type was sawn lumber and the species was modified from the design part of the user interface, sometimes the analysis model was not updated correctly to reflect the selected species. The output would indicate that the analysis results had used a different species to the design results.
[TEDDS-4797]1 - Fixed section source data always being specified in US units which prevented the section from being correctly re-read by analysis ui.
[TEDDS-4800]1 - When the design option for the lumber type was modified the material used in the analysis model was not updated accordingly.
[TEDDS-4802]1 - When a US timber section was modified from the 2D analysis user interface the lumber type was not assigned in the design model and may therefore not have matched the setting in the design options dialog.
