A problem of modelling bending-shear-axial interaction

QI · Post by QI » Mon Apr 16, 2007 1:34 am

hi everyone!
I am a new leaner of opensees in china ,
I am my master paper about modelling bending-shear-axial interaction in a finite-beam element,i use the model of nonlinearBeamColumn and add a Hysteretic uniaxialMaterial to fiber section with aggregrator command,but the result is disillusionary

I have two problemes to ask :
1.How can I model bending-shear-axial interaction in opensees ?

2.Can I implement bending-shear-axial coupling only through the section aggregrator command? Has OpenSees considered bending-shear coupling only through the section aggregrator command?

Can you email me some information and examples about modelling bending-shear-axial interaction in opensees
thanks very much ahead of time !
Any reply about the problems will get an ocean of thanks!

silvia,Limit State Material has not added in opensees1.7.3,has it?
Limit State Material can not work, How shoud I do next ?
