To perform steel design per the GB 500017 code, use the following procedure.

1. On the Chinese Steel Design ribbon tab, select the design mode in the Design group:

   Option	Description
   General Design	Select this mode for common design per GB 50017-2017 and the limited seismic provisions of GB 50011. This tool is disabled if GB 50018 is selected.
   Performance Design	Select this mode for common design along with seismic (fortification) performance check of GB50011-2017, chapter 17

2. On the Chinese Steel Design ribbon tab, select the Design tool in the Design group.
   
   The Chinese Steel Design dialog opens.
3. (Optional) On the Structure tab, set the following options as needed:
   1. Click Default to make any changes to the default design parameter. This parameter set is used for any members which do not have a named parameter set assigned.
      Tip: Any members without a parameter set name associated with it in the view window will use the default parameter set.
   2. Select the Design Range option: For the general design mode, this is either all members or on those selected. For the performance design mode, this is by structure storey.
   3. For general design, check the Seismic Design option to include seismic design and then select the Seismic Precautionary Intensity level from the drop-down list.
   4. For performance design, select the Gravity Load, Seismic-H (horizontal), and Seismic-V (vertical) load cases and directions as appropriate.
   5. Select the optimization options applicable.
4. Click Design. The design and optimization process is displayed.
5. Click Done. The Results page opens. The members are color-coded by design status in the view window as well as in the Summary Results table.
   Tip: If you would like to change or add to the design result columns displayed in the Summary Results table, select the Table Settings tool in the Results group on the Chinese Steel Design ribbon tab (active when the Results page is selected). From there you can make changes to the table columns.
6. Select a member either in the view window or in the table to display design results in the Member Detail Result table.
