Truss Engineering

Truss labels indicate truss status

The color of the truss label indicates the status of the truss in engineering. Red is mark for note engineered or failed truss and green for passed one. If the single truss state has been used, yellow color is mark for passed trusses, but the trusses must be checked together with others to make sure that changes made in single truss state will not affect the other trusses.

Trusses after single truss state. Yellow ones are passed, but require a check in the layout with others to make sure that changes done in single truss state will not affect the trusses near by.

Improved tool to check design errors

Save time and find weak points or design errors more easily. The tool for showing design errors and warnings is now separated from the calculation result tool. You can dock the error dialog box to the left or right side of the screen or drag it to another screen. Checking weak points does not hide the 3D view, connection errors or other things that are causing member failing, any more. You can find problems more easily and their location be displayed more accurately.

Deflection information of truss members to engineering printout

You can now add deflection diagram for predefined parts in engineering printout.

Select building code you need

Vertex supports building codes as follows:

  • Eurocode 1993-1-3 (Europe, UK)
  • AS/NZS 4600-2005 (Australia/New Zealand)
  • GB 50018-2002 (China)

Building codes are not part of the environment package any more. They are now in building codes library and you can select any of those existing ones. Program asks which building code is used by default when you start the new version for the first time. You can disable the question from next time by check box below the building code selection:

Later on the building code can be changed also from the project settings or by using the tool on the engineering tab.

Profile grade mapping tool

The profile grade mapping tool can be used to set correct grade based on the area. There are three areas defined by default in the system settings:

  • AU Australia
  • EU "European Union"
  • PRC "People's Republic of China

Grade mapping is used when inserting/generating parts. The grade of existing profiles are edited manually.

Grade mapping is defined in the system settings (grade_map): File → Preferences → Edit (Edit system settings common for all users). The Vertex installation package contains example mapping from AU to PRC and from EU to PRC for grades as follows:

From (Area Grade)

To (Area Grade)
AU G350PRC Q345
AU G500PRC Q345
AU G550PRC LQ550

Stop load transfer, set profile to be grounded member

You can stop load transfer to the load bearing beam below the truss, if you are only engineering trusses.  You can set the bearing beam as a grounded member in the profile properties. A grounded member means that it is supported and the load transfer is stopped to this beam. However, be careful not to set this property for the members above the trusses, which are carrying loads and supported by trusses below.

Select specific profile much faster than earlier

You can now select profiles more precisely than earlier. Use profile parameters for common profiles or truss and panel members to filter selection of the profile. If you want to select all similar top chords, for example, open selection filter and fill in selection parameters. You can also pick up properties from an existing profile by pressing Select button in the dialog box and selecting a profile from the building. You can use this tool to change the profile grade of all truss members at the same time, for example.

Bearing and Grounded properties for brick and concrete columns

You can now set bearing and grounded properties for parametric brick and concrete columns. These are located in the Columns folder in the Building Component browser.

Screw connection between panels

Direct screw connection is needed to connect panels for engineering purposes. A panel may be above trusses and it may transfer loads from the roof surface or other structures to the cold formed steel trusses. Screw connection between panels are needed to solve load transfer through the panels to structures below. If panels are not connected, load transfer calculation can be performed.

Truss that are needed only for detailing (production information), but not for engineering

There may be trusses in the model, which are not engineered, but they are needed for production. Typically those trusses are in such location that they are laying on above the bearing member full length and may be supporting very light load from the roof.
