I am trying to simulate a concrete arch bridge under seismic loading. The bridge has a span with the length 40 meters. A nonlinear time-history analysis is performed. A nonlinearBeamColumn element is used.
When I request the response quantities from a specific section along the element length, using command;
"recorder Element -file ElementSectionForce/ElementForce41.txt -ele 41 section 1 force"
I got result file with five column for each time steps. Now, i don't know what these five values represent as i was expecting just two column for Fx and Mx.
Please help me to find my problem.
Thank you.
Hello,
In case of 3D problem, 6 dof, the order of the recorder will be Fx, Fy, Fz, Mx, My, Mz.
Thank you for your reply,
In that case i should have got 6 columns but my output file has just 5 columns.
The output file for the above mentioned element is attached below.
Thanking You..!
Let's check the reaction force at a time step, and you can calculate the global forces at a given section on the arch.
Thank you for reply,
calculating forces for each section using obtained reaction manually, that is what you mean, right?
