SMAR 2024 – 7th International Conference on Smart Monitoring, Assessment and Rehabilitation of Civil Structures RC beams externally strengthened by steel plates: experimental database and preliminary analysis Annalisa Napoli a , Enzo Martinelli a , Maria Rosaria Pecce b, * a Department of Civil Engineering, University of Salerno, Via Giovanni Paolo II 132, 84084 Fisciano (SA), Italy b Department of Structures for Engineering and Architecture, University of Napoli Federico II, Via Claudio 21, 80125 Napoli, Italy Abstract External steel plating is a popular technique for the flexural strengthening of RC beams thanks to the ease of application which does not require skilled labor, the relatively low-cost and the optimal mechanical properties of the steel material. Research on externally plated RC beams is much older than the literature related to the strengthening methods employing fiber reinforced (FRP) materials which were more recently developed. Despite this, the number of FRP applications is far greater than those available for steel applications, as also corroborated by the widespread of several international guidelines for the FRP strengthening design of RC structures. Conversely, the in-situ applications with steel plates are still very common and often preferred to FRPs, but they are not well supported by clear design indications. This paper contributes to filling this knowledge gap by presenting the results of a preliminary study on the flexural performance of steel-plated RC beams. A large experimental database was compiled from the literature, which includes three/four- point bending tests performed on RC members variably reinforced with external steel plates. The database is in-depth examined by considering the following main parameters: layout of the external steel plating, shape of beam’s cross section, mechanical percentages of both external steel plate and beam’s longitudinal steel reinforcement in tension, and failure mode. The collected data is useful for a theoretical study o n beams’ flexural performance , which is under preparation. © 2024 The Authors. Published by ELSEVIER B.V.
