How to Use P-Delta Analysis in RISA-3D

P-Delta analysis induces shears into the model due to the second order effects of axial forces and lateral deflections, and can be automatically checked in RISA-3D with a few simple steps.

What is P-Delta Analysis?

When a model is loaded, it deflects. The deflections in the members of the model may induce secondary moments due to the fact that the ends of the member may no longer be vertical in the deflected position.
