How to input column nonlinearity like P-M2-M3 interaction

Post by ankurjain » Thu Oct 22, 2020 7:26 pm

Sir how can we input column nonlinearity like P-M2-M3 interaction for column for non-linear analysis. ??

For beam, we can assign ZeroLength Element with ModiMKPinching type Materials. But what about columns ? We need P-M interaction for that so how shall we input that data ?

The best way of considering the P-M2-M3 interaction is by defining a fiber section which automatically considers the interaction between axial force and the two moments.
