Interaction Diagram of Steel-Concrete-Steel Sandwich Structure

Abstract:

The article is focused on the description of the modified interaction diagram, which was developed bythe author for a simplified check of steel-concrete-steel sandwich, which is loaded by a combinationof axial forces and bending moments. The method was developed for the needs of a feasibility studyof steel-concrete guard vessel of fast reactor Allegro. In the introduction, there is a short descriptionof steel-concrete-steel sandwich construction altogether with its design problematics, which closelyrelate to the author´s motivation to develop the interaction diagram. Next parts of the article arefocused on the interaction diagram itself. In the theoretical part, there are mostly mentionedconsiderations and assumptions of the calculation, which were inspired by classical reinforcedconcrete principles, and which also consider the requirement for elastic analysis given by the type ofthe designed structure (guard vessel). Then, there is introduced the general process of calculation ofevery single point of the interaction diagram. The article also includes the practical part, where a shortexample of calculation is shown, and in which the interaction diagram for the chosen geometry of thecross-section of steel-concrete-steel sandwich is assembled. Finally, there is a discussion about theusability of the modified interaction diagram for the guard vessel of fast reactor (rotational shell) orother types of structures. There is also presented an alternative method for steel-concrete-steelanalysis, which is then compared with the interaction diagram method.
