Thank you Selimgunay, I do not use rigid diaphragm and the structure that I have modeled is 3 dimensional and includes 26 nodes and 156 degrees of freedom. I copied the first captured mode shape below: -0.146233 0.00021218 0.000449344 -0.000124599 -0.0775583 2.04E-09 -0.144418 0.000195553 0.00042814...

Yes I did, I used the following command to capture the first 8th mode shape of the structure, but I do not know for which direction they are, for instance: whether the first mode shape is for X direction or Y or Z directions! The command I used: for { set k 1 } { $k <= $numModes } { incr k } { recor...

Dear all, I have modeled a 3D reinforced concrete structure. I wonder how to capture its mode shapes in the three X,Y, Z directions . Is there any command to do so? I have used the "Node Recorder" command to capture the first 8 mode shapes of the structure, yet I couldn't recognize for whi...

Hi, I have modeled a 3D RC structure, similar to the example provided in the software's manual, to record the global stiffness matrix. I used the static analysis and printA command. The problem is that although my structure has 96 DOFs, the output K matrix is 45*45. I couldn’t figure out what’s wron...
