Pdeltaeffekter
Pdeltaeffekter, also known as the P-delta effect, is a structural engineering phenomenon that occurs in slender columns or frames subjected to lateral loads. The term originates from the combination of the axial force (P) and the resulting lateral deflection (delta), which together create an additional moment on the structure. This effect is particularly significant in tall buildings, bridges, and other slender structures where lateral loads such as wind or seismic forces are present.
The P-delta effect arises due to the interaction between axial compression and lateral displacement. When a

In practice, the P-delta effect can influence the overall stiffness and strength of a structure, sometimes requiring
