Abstract

Stiffening structures, wing structures and methods for manufacturing stiffening structures are provided. In accordance with an exemplary embodiment, a stiffening structure includes a first longitudinal member, a second longitudinal member, and a first rib that extends from the first longitudinal member to the second longitudinal member and is integral with the first longitudinal member and the second longitudinal member. The first longitudinal member has a first wall, a second wall and a joining wall that joins the first wall and second wall. The first wall, the second wall and the joining wall form a space having a trapezoidal shape.
