Deflection along multiple bars

Deflection along multiple bars

I have a beam that is modeled using multiple bar members. I want to find the deflection diagram along the beam and not just one bar of the beam. I was trying to use DJ1 and DJ2 function to do this but I can't seem to get it to work.

My input is:
SECTION 0.0 0.25 0.5 0.75 1.0 ALL
DJ1 65 MEMBER 63 64 65
DJ2 68 MEMBER 63 64 65


I don't get any errors using this, but I also don't get an output.
Please help! Thanks!

RE: Deflection along multiple bars

The parameters DJ1 DJ2 are used in the design phase for checking deflections. You can do a deflection check for the physical member using these parameters which will be output in the analysis output file. By the way, you need to add the DFF parameter too to get the deflection checked.

However if you are interested in plotting the deflected shape of the physical member, one way would be to first define a physical member consisting of these 3 analytical beams. From inside the modeling mode, you can select the 3 beams and right click your mouse to choose the Form Member option to create the Physical Member. After you run the analysis, you can select the physical member cursor and double click on the physical member to bring up the Physical Member dialog box within which you will be able to see the deflected shape for the full physical member.
