Tag: second-order effects

P-delta analysis is a structural analysis technique that considers the second-order effects caused by deformation in structures subjected to lateral loads like wind or earthquakes. In this article, we’ll explore how P-delta analysis works and why it’s important for the design of tall or flexible structures. P-delta analysis accounts for the effect of vertical loads on the stiffness and internal forces of a structure, which in turn influences its response to lateral loads. This analysis technique is used to modify the stiffness matrix by using the structure’s deformed shape and…
