Geometric Nonlinearity

Post by salarmanie »

Dear vesna,
How can one capture the effects of Global p-delta effects? and which of the two transform methods (namely Pdelta or corotational) is better for capturing geometrical effects while analyzing 3-D building frames with concentrate plasticity?
Thanks
vesna

Corotaional is the exact formulation and PDelta is its approximation.
