Dear moderators,
I wonder if you could possibly help me regarding the aforementioned issue.

Thanks in advance

Dear Prof. McKenna, I recently have found a new material named "Cable Material" and I want to use it in order to simulate a single cable divided into some truss elements. However, I didn't find any general information about the specific characteristics of this material. Does this material ...

@alirezaarab: I tried this command but OpenSees just ignores it!!!! It looks as though you had a similar problem. How was it solved? Why nothing happens when I do printA?

Hi I want to simulate a concrete shear wall in opensees, based on an initial model in SAP2000. The shear wall has a 2x6(2 horizontal rows and 6 vertical columns) mesh grid and is connected to the ground by 7 nodes. What is the simplest way to define a shear wall in opensees like one defined in SAP20...

I removed all [eigen 1] commands but the error was not solved. After using [eigen 3] instead of [eigen 1] it worked erfectly. I think it's a little strange!!!
Thanks a million for your help.

this is my code: wipe model basic -ndm 2 -ndf 3 #Setting of parameters.............................................................. set b 5.; #Span Length set h 3.; #Story height set M 100000; #Story mass (kg) set E 2.e11; #Elastic modulus of steel set Fy 2.354e8; #Yielding stress of steel #reminde...

Hi dear friends, I created a 2D model of a simple 3-story steel frame. After using [eigen 3], the following results are shown: 2.794791e+002 2.419159e+003 6.834482e+003 but when I want to get eigen vectors, for all nodes and dofs, all outputs are equal to zero when the mode number is 2 or 3. The syn...
