convergence issue in seismic analysis of beam column joint
I am not able to find a solution to this problem.
*** ERROR *** CP = 15887.891 TIME= 17:47:40
Solution not converged at time 1889.2 (load step 96 substep 15).
For reference, I have attached the solve.out file in "txt format"
too with this question.
Note- At load step 96, I am already using a minimum of 35 substeps and a maximum of 50 substeps
Topic:- Seismic analysis of beam-column joint.
Analysis system:- Static structural
Loading:- Cyclic loading (cyclic displacements)
- CPT 215 element for concrete ( because I am using Druger-Pager failure criterion)
- Structural steel non-linear for reinforcements
Newton- Raphson: UNSYMMETRICAL
force convergence: Tolerance-5%
minimum Reference-10 N
displacement convergence: Tolerance-3%
minimum Reference- 3mm
