Bracing

Structural Design User Guide

AVEVA E3D™ provides the user with standard bracing configurations which allows the user to create simple bracing configurations which can be highly advantageous during the design process. (for example: avoids the need to create individual bracing sections).

Bracing Configurations

On the SECTIONS tab, in the Tools group, click Bracing, select Bracing Configuration from the drop-down list to display the Bracing window.

Note:

The user can create bracing configurations with the appropriate connections at the end of the bracing sections, between GENSEC elements.

The user must specify a storage area for the bracing configurations, by default the storage area is unset.

In the Section Data part of the Bracing window, allows the user to define the profile, specification and attributes for the bracing configuration (replacing the default specification). Select Profile to display the Section Specification (Form) window is displayed.

The functionality available to the user is identical to that available from Sections Settings, refer to Default Section Specification for more information.

From the Bracing Plane drop-down list select a design aid for the creation of a bracing configuration:


Derived by Section	The bracing plane direction is orthogonal to both the first section selected and the incoming nearest to the first selection. Derived by Section is the default and the most commonly used.
Derived by Points	Allows the user to add bracing between two sections that do not have a third section connected directly between them. The bracing plane is created by projecting the second selected point onto the first selected section.
Defined	Allows the user to define the bracing plane explicitly and projects the selected points onto the defined plane. The Bracing Plane and Positioning Control windows are displayed.

In the Available Bracing Configurations part of the Bracing window is populated with the supplied standard bracing configurations along with a parameterised graphical representation of the configuration.

The parameterised diagram shows the details of the selected configuration. The representation displays the dimensions which must be specified (A, B) and the order in which sections that already exist must be picked (1, 2) so as to position and connect the bracing members correctly.

Click Apply to create the Bracing Configuration, depending on the selection made in the Available Bracing Configurations window determines the window displayed to the user.

Click Cancel to discard any inputs and close the Bracing window.

For the purposes of this user guide, only the A/K Bracing functionality is described.

From the Configuration part of the A/K Bracing window, select the required configuration, by default Bracing A is selected.

If required, input the initial gap into the Gap A and B fields, refer to the 3D representation for reference.

If the Confirm check box is selected, design aids represent the bracing plane and elements are displayed.

The user is prompted to ‘Pick first section’, the 3D representation on the Bracing window can be used as a guide.

Click Accept to create the bracing configuration.

Click Reject to discard the bracing configuration.

Click Dismiss to close the A/K Bracing window.

When the user is satisfied with the configuration shown in the 3D view, accept the creation of the sections which forms the bracing members and then click Cancel to close the Bracing window.

Bracing Gaps

As part of the design process, once bracing configurations have been created the bracing gaps may require adjusting. On the SECTIONS tab, in the Tools group, click Bracing, select Bracing Gaps from the drop-down list to display the Bracing Gaps window.

The Brace Gaps window is populated with all the available gap types which can be modified, along with the default Gap and a graphical representation of the Brace Gap. Select the required gap type and default gap, click Apply, the Brace Gap(s) window is displayed.

Click Cancel to close the Brace Gaps window.

From the Brace Gap(s) window, use the 3D representation window as a guide, the default is displayed in the Gap A field.

By default the Confirm check box is selected, design aids represent the bracing plane and elements are displayed in the 3D view.

The user is prompted to ‘Pick first section end’, use the 3D graphical representation as a guide.

Click Accept to create the bracing gaps.

Click Reject to discard the bracing gaps.

Click Dismiss to close the Bracing Gap(s) window.

When the user is satisfied with the configuration shown in the 3D view, accept the creation of the sections which forms the bracing members and then click Cancel to close the Bracing Gap(s) window.
