Wrong message of the VBrace model with OpenSees Navigator

Post by YoungXu »

Hi,
I build a model of VBrace with Navigator, but there are some problems which shows that
"WARNING: Invalid option -cMass in: element Truss 9 $iNode $jNode $A $matTag <-rho $rho> <-doRayleigh $flagh>
Invalid Args want: element TrussSection $tag $iNode $jNode $sectTag <-rho $rho>
TclElementCommand -- unable to create element of type : truss
while executing
"element truss 9 1 7 +2.38E+03 1 -rho +0.0E+00
-cMass 0 -doRayleigh 0"
<file "Elements.tcl" line 28>
invoked from within
"source Elements.tcl"
<file "C:\......\BBraceModel.tcl" line 45>"
How can solve it? Please help me! Thank you very much!

Re: Wrong message of the VBrace model with OpenSees Navigato

It looks like you are using the new consistent mass matrix option for the truss element. Please make sure that you use the latest version of OpenSees 2.4.5 because the consistent mass option is not available in earlier versions.

Sir, you mean the version 2.5.3 of Navigator is not for the version 2.4.4 of OpenSees? Sir, by the way, recently I use a simply portal frame to run the Hybrid Testing, but the simulation displacement(displacement data small like 0.5mm) is not equal the actuator's displacement(displacement data very large like 50mm), do you know why? And I sent the Email to you. Happy new year, thank you!
