Show Influence Lines/Surfaces

Forms:  Show Influence Lines/Surfaces, Select Frame Relative Distance

After lanes have been defined and a moving analysis case has been defined and run, click the Home > Display > Show Influence Lines/Surfaces command to display the Show Influence Lines/Surfaces form.

The influence lines can be displayed for the various displacements, reactions, forces, moments, shears, and torsion or axial loads on joints, frames, shells, planes, asolids, solids, and links resulting from a unit load on a defined bridge lane in the structure.

The process for displaying influence lines/surfaces is as follows:

  1.  Define lanes

  2.  Assign lanes to a Bridge Object

  3.  Define vehicles

  4.  Define vehicles classes

  5.  Define a bridge response(s)

  6.  Define a moving load case(s)

  7. Run the analysis

  8. Click the Home > Display > Show Influence Lines/Surfaces command to display the Show Influence Lines/Surfaces form. Use the form to specify the influence lines to be plotted:
