Abstract text:
The perimeter enclosures of single-storey buildings are in most cases build from corrugated metal sheets. For metal structures there are a lot of studies that have led to the creation of design guides that take into account the concurrence between the corrugated sheet and the metal structure. In the case of reinforced concrete buildings, the problem is still insufficiently thorough. There are no methods nor calculation models to help the design engineer determine the sheet contribution to the lateral stiffness of the frame. The additional stiffness added by the corrugated sheets it is often overlooked in the global design process. In order to better understand the interaction between the corrugated sheets and the reinforced concrete frame, we have carried out an experiment on a real prefabricated reinforced concrete frame structure made at a 1:3 scale. The steps followed to run the experimental test are described in the ACI T1.01 standard.
Key Words:
