dear seismosoft support
I have modeled one column and then the time history dynamic analysis have been done, but when I control the axial reaction of support with the element axial force they don't coincide to each other I want to know the reason that ,also the seismostruct gives one axial force for each element if this is a maximum or mean values of the two ends
tanks alot

Hi khajehdehia,

Have you considered already the Notes in pages 'Theoretical Background/Geometric Nonlinearity' and 'Post Processor/Global response parameters' of the Help System or User Manual?
