I have one last question = is there a way to output 'total moment/shear on bridge' then? not total moment on individual girders Vol.1_51_How to verify for the uplift due to moving load_And how to obtain the corresponding vehicle positioning.pdf mct file using, Tools > MCT command shell, the said vehicle position is added as a static load case to existing static load cases. Moving load combinations along with permanent load.Ĭlicking on ‘Write Min/Max Load to File’ option, generates a. NOTE: It is recommended to check the uplift results for Only support nodes could be selected as Key node. Enter the Key node, node with the maximum uplift.įollow the same steps for reactions as well, except that In the moving load tracer menu, select the appropriate moving load case (max)Ģ.

To track vehicle position causing the maximum uplift at the particular node, Invokeġ. Reactions at supports for moving load combination (min case).

Positive value of DZ implies there is an uplift at that support.Īlternatively, same could be checked by verifying the For the moving load combinations (max case) check the deformed shape in the direction of gravity (DZ) at the support locations.Ģ. Go to Results > Deformations > ‘Deformed Shape…’ġ. To know the corresponding vehicle position, Moving Load Tracer option can be used. Other lane could be defined with eccentricity of 2.1m.Īctivate the maximum displacement for the generated moving loadĬases, to view the uplift. Definition of one such lane is shown below.

If it is intended to just move vehicle in a lane, then I'd recommend using the Transverse lane optimization option in traffic lane definition. Because in this case, the governing factor for distance between 2 vehicles is just margin and minimum transverse distance. In that case, I wouldn't recommend using moving load optimization. So, the distance between the vehicles could be more than 1.2m as well. So, to summarize, you want the vehicle to move only in 4.2m width and do not want vehicle of lane 1 to more over lane 2 par. My colleagues are having the same issues. It seems when I run my model, either the Lane 1 and Lane 2 boundaries are overlapping as opposed to the diagram below or the lane boundary is extending past the carriageway. So for example, for a 8.2m carriageway, I would like to have two 4.2m lanes with each vehicle 600 mm from its lane boundary, so that they keep a distance (margin) from the centerline of the bridge. I would like to keep margin at 600mm but have minimum distance between two vehicles at 1200mm. Margin and minimum vehicle distances are two different things. Do let us know if further assistance would be required.
