Form: Moving Load Case Results Saved
The Analysis > Bridge > Bridge Response command can be used to display the Moving Load Case Results Saved form. Alternatively, click the Home > Bridge Wizard command; highlight the Moving Load Case Results Saved item; and click the Define/Show Results Saved button to display the Moving Load Case Results Saved form.
Analysis of moving load load cases involves calculations that are computationally intensive and can take a significant amount of time in larger models. The moving load case results saved parameters allow explicit specification of the analysis results for a moving load load case. Only the results specified will be calculated and saved by the program.
If correspondence is specified to be considered, then for each maximum or minimum response computed, the corresponding force, moment or stress quantities that occur at the same time as the maximum or minimum value also are reported. For example, in a frame object, when the maximum M3 moment is calculated, if correspondence is specified the P, V2, V3, T and M2 values that occur at the same time as the maximum M3 value also are reported. Including correspondence increases the program calculation time and the quantity of response output.
The options on the Moving Load Case Results Saved form can be used to selectively control what information is calculated for joints and frame objects in the computationally intensive moving-load analysis.
Response Category check boxes. Check each of the response categories to be analyzed (Displacements, Reactions, and so forth).
Select Group drop-down list. Choose the group for which responses are to be computed. The default is ALL.
Important: If no groups are selected for response calculation, no results will be produced for moving-load analysis.
Correspondence check boxes. Check the Correspondence check box associated with a response category to use the Max/Min Correspondence in design of frame sections when using moving loads. This is a very time-intensive operation so use it only when it is required.
Method of Calculation. Select Exact or Refinement Level and enter a value in the edit box. The value entered can be any positive integer. This feature provides a "fast analysis option" for preliminary analysis. The larger the integer the greater the level of refinement.
Allow loads to reduce response severity check box. Check this check box to moderate the severity of the response based on the loads specified for the moving load analysis.
