Fenix is capable of performing P-Delta analysis. The following pages will guide you through enabling P-Delta ($P\Delta$) effects and understanding how Fenix implements P-Delta analysis.
Note that although P-delta ($P\delta$) is not explicitly accounted for mathematically, it will inherently be considered assuming that elements are meshed sufficiently between end points. We recommend meshing a single design frame element with a minimum of six (6) analytical elements to appropriately capture P-delta effects, although the user may wish to carry out sensitivity studies on a project-by-project basis. Similarly, shells with sufficiently small mesh sizes should adequately capture P-delta effects.
