when i model rigid diaphragm in one floor , the axial forces in the beam correspond to that floor have neglect force ,i run my model , i checked my axial force in beams , and this force is neglec ,

hi vesna instead of your suggestion , i write "rigid link bar " , " rigidLink $type $masterNodeTag $slaveNodeTag " bar only the translational degree-of-freedom will be constrained to be exactly the same as those at the master node for before example rigidlink bar 21 22 rigidlink ...

"rigid diaphragm command " in 2D frames does not work , it works in 3D issues , so i have modeling 2D frame with 3 bay and 3 story , and i try to rigid diaphragm in every floor that all of nodes in every floor have the same displacement in x direction , my beam and column are element nonli...

how i model rigid diaphragm in 2d frame ? should i use equaldof command ?

how do i model single degree of freedom model in modal pushover analysis in opensees ? plz help

hi , are you iranian like me? i have this problem too , can you solve it at last?can any body help me?
