Define Parametric Variations Form

Parametric variations can be used to define variations in the deck section along the length of the bridge. Almost all parameters used in the parametric definition of a deck section can be specified to vary. More than one parameter can vary at the same time, if necessary. Each varying parameter can have its own unique variation. Example uses of parametric variations include varying the bridge depth and the thickness of girders and slabs along the length of the bridge. The variations may be linear, parabolic or circular.

After a variation has been defined it can be assigned as part of the deck section assignment to bridge objects (see Step 7).

Click the Components > Superstructure Item > Parametric Variations > Expand arrow command, or on the Bridge Wizard form select the Parametric Variations item and click the Define/Show Variations button, to display the Define Parametric Variations form and add, modify or delete a parametric variation definition.

Note:  The Define Parametric Variations form also displays when the Define/Show Variations button on the Bridge Section Variation Definition form is clicked.

    1. Highlight the name of a previously defined variation definition.

    2. Click the Add Copy of Variation button to display the Variation Definition form. The form will be "pre-loaded" with the parameters specified for the definition selected in Step 1.

    3. Make the necessary modification to the form, if any, to complete a new parametric variation definition.

    1. Highlight the name of a previously defined variation definition.

    2. Click the Modify/Show Variation button to display the Variation Definition form.

    3. Use the form to modify the definition.

    1. Highlight the name of a previously defined variation definition.

    2. Click the Delete Variation button to be delete the definition.
