Numerical and Experimental Studies for the Development of Direct Strength Design Rules for Locally and Globally Slender Hollow SectionsThis paper discusses the strength and stability of slender hollow sections with flat faces and different cross-sectional geometries in terms of the ""Overall Interaction Concept"" (OIC). The results shown are developed in the framework of the European (RFCS) research project HOLLOSSTAB. The paper focuses primarily on the behavior of bespoke cross-sections with stiffened faces respectively mono-symmetric cross-section. This allows for a more general verification of the general viability of OIC-type design rules for the direct strength design of hollow sections of general shape and material. The scope of the study consists of an extensive experimental campaign, coupled with a comprehensive series of numerical tests. The initial discussion of the results in terms of the OIC approach highlights its challenges and potential.
