The building industry is seeing a rapid uptake of joining two or more cold-formed steel sections to form large built-up sections with high carrying capacities. The joining consists of screws, or similar fasteners, placed intermittently along the member. The ease of joining encourages innovation in forming versatile new built-up section shapes in expanding areas of application. The project will provide guidelines and numerical tools for the efficient structural design of built-up sections through experimental and theoretical research, studying the new failure modes pertaining to built-up sections, the increase in strength achievable from composite action and the optimum arrangement of fasteners.

建筑行业正在迅速采用连接两个或多个冷弯型钢，以形成具有高承载能力的大型组合型材。连接由螺钉或类似的紧固件组成，沿构件沿着间断地放置。连接的方便性鼓励了在扩展应用领域中形成多功能新型组合截面形状的创新。该项目将通过实验和理论研究，为组合截面的有效结构设计提供指导方针和数字工具，研究与组合截面有关的新的破坏模式，通过复合作用可实现的强度增加以及紧固件的最佳安排。
