Your model is inaccurate.
- slabs with diaphragms are not flat
- some columns are located in wrong planes
- some nodes on small roofs are loacted in fact 0,5-1cm above the roofs 310 312 367 368 282 284 373 374
- some nodes should be located in the same location , like 683 684 688
I do not understand idea of "hohn" release
To correct model :
- delete meshes
- run detailed correction to Structural Axes with tolerance 2cm
- corect nodes on the roofs
- correct location of bars 1203 1204 1327
- mesh model
- delete "hohn" releases from bars or correct them
Corrected model in the way described above attached.

Thank you so much.I also have a question.Could you explain about a few methods such as " Newton- raphson iteration and BFGS iteration?When can i use these method?
Rafal Gaweda
I have fixed model according to your guidline. But it is appeared some problem when i ran calculation. I increased maximum number of BFGS corrections. I can't solve these problem.
Use Newton-Raphson
