Is it possible to obtain corresponding forces for different members?

Extended Question: In a During bridge analysis, is it possible to find the max/min maximum and minimum response in one member, and then using the case that causes the max/min force in that member use that same loading condition to find the corresponding responses for the remaining response in other members? In other words, is there any way it possible to compute the bridge live load case that which maximizes one response in one member, in order to use this LL case then use the same loading to compute the forces in the other elementsmembers?

Answer: The program can calculate corresponding forces for During influence-based moving-load analysis (the correspondence can be set via "Define > Bridge Loads > Bridge Responses); however, the correspondence is reported for a given location. For example, you can obtain shear forces at midspan corresponding to the maximum moment at midspan. To , correspondence between response parameters may be reported for a given location within the structure in CSiBridge via "Analysis Tab > Bridge > Bridge Response > Moving Load Case Results Saved > Correspondence". For example, when the maximum moment is resolved at an element midspan, the corresponding shear force at the same location, under the same loading condition, may be obtained through this process.

Step-by-step moving-load analysis should be run to obtain concurrent forces for different members, you could run step-by-step moving load analysis, identify the step that causes min/max forces in a given member and then review forces in other members of interest . Once run, the step in which minimum and maximum forces are induced in a structural member should be found, then the forces in other members may be reviewed for that load step.
