additional punching shear due to unbalanced moment
additional punching shear due to unbalanced moment
(OP)
dear experts
regarding to the additional punching shear due to unbalanced moment,
are the finite elements programs(sap,etab or safe) taken into considerations the effect of the unbalanced moment during analysis or i have to use the ACI methods (EFM or DDM) to get this moment, because when i am checking the punching i get the normal force and moment from the columns and use any spread sheet to check. but if the normal force from the finite elements programs included the additional shear due to unbalanced moment the loads will be duplicated .

but if u see the how the safe check the punching shear u will find the moments in two directions Mu2 and Mu3 have been taken into consideration with the shear force so the shear force haven't been increased due to unbalanced moment.
