Use this dialog to select calculation options for the design of steel / aluminum / timber structure members.
- Access
-
- Select the Steel Design layout, or Timber Design layout.
- Click
(Steel/Aluminum Members Design), or 
(Timber Members Design) on the toolbar.
Verification Options
The Verification Options group contains the following options.
- Member Verification
- Verifies each member of the selected list.
- Group Verification
- Verifies each member of the selected group.
- Group Design
- Verifies the design of each section family of the selected groups.
-
Note: At least one group must be defined in order to use this option.
- If you want to run the calculations on groups of members, select Optimization, and then click Options to set the parameters for the groups of members.
- Optimization Options
- Runs the calculations on groups of members.
-
Note: Groups of members must be defined before the optimization process is started.
Code requirements / Limit states
The title and options available in this group depend on the selected code.
Select a code requirement or a type of limit state, and then enter one or several load cases for it. Alternatively, click List to select a list of load cases for the selected option.
- Code requirements (ASD)
- The Code requirements group is displayed for US codes which use the Allowable Strength Design (ASD) method, such as:
- ANSI 2005,
- ANSI 2010,
- ANSI/AWC NDS-2012.
- Strength
- Calculates the strength of the member.
- Deformation
- Calculates the deformation of the member.
- Fire
- Uses the limit states to perform a Fire analysis.
- Limit states (Other codes)
- This group contains the list of ULS and SLS, as well as load cases to consider for the verification.
- ULS
- Performs calculations to the Ultimate Limit State.
- SLS
- Performs calculations to the Serviceability Limit State.
-
Note: If you select this option with the ANSI/AISC 360-05 or the ANSI/AISC 360-10 codes, the lists of Dead loads, Live loads, and Total loads are also displayed.
Calculation archive
- Save calculation results
- Saves the results of steel member verification and design.
-
Note: Saving the calculation results is useful if you want to perform several verifications on the same model, and avoid time-consuming recalculations. This option also prevents the accidental loss of data, in case of a power outage for example. You can deselect this option if you do not want to save your calculation results.
- Results storage
- Opens the Calculation Result Archive dialog which contains all saved verification and design sessions. Note: All calculation sessions are saved with the model in an RTD file.
- Configuration
- Opens the Configuration dialog which allows you to define the parameters applied during the verification of a steel member.
