    Gravity load deflection doesn't respond to tensile force in RISA

    Josh, Your suggestion of changing the density of my round bar tension member is a great one. I'm not finding a way to do that or information in RISA on doing it. Can you help with this? Thanks.

    Gravity load deflection doesn't respond to tensile force in RISA

    Ah, very good information! Yes, it appears to be treating the tension rods as a beam in bending moment. OK, I'll stop being concerned. Thanks a lot!

    Gravity load deflection doesn't respond to tensile force in RISA

    I am designing a jib. There is a pair of 3/4" x 20' long round bars as tension members to support the wide flange that the trolley runs on. RISA says that these round bars will deflect 13 inches in the center. This might be the case if there were no tension but in reality they don't deflect at...
