The proposed study analyze the structural performances of built-up columns made by open FRP (fiber reinforced polymer) profiles. These open profiles are connected to each other and each column has two typologies of connection: the first guarantees the junction between the two channel- web and the second one assures the connection between the built-up-web and the external flanges. Specifically, the research verify the influence of the anisotropy of the material and the shear deformability as well as the interaction between local and global buckling on the overall bearing capacity of the assembled column. The analyzed case regards a built-up column made by four FRP channels made by pultrusion process and connected along the column with steel bolts. The study proposes both a numerical and experimental analysis. The comparison between these, aims to better fit particularly the influence of shear and to determine the local mechanisms of diffusion and the load’s distribution through the bolted connection and the four FRP channels.

Abstract
The proposed study analyze the structural performances of built-up columns made by open FRP (fiber reinforced polymer) profiles. These open profiles are connected to each other and each column has two typologies of connection: the first guarantees the junction between the two channel- web and the second one assures the connection between the built-up-web and the external flanges. Specifically, the research verify the influence of the anisotropy of the material and the shear deformability as well as the interaction between local and global buckling on the overall bearing capacity of the assembled column. The analyzed case regards a built-up column made by four FRP channels made by pultrusion process and connected along the column with steel bolts. The study proposes both a numerical and experimental analysis. The comparison between these, aims to better fit particularly the influence of shear and to determine the local mechanisms of diffusion and the load’s distribution through the bolted connection and the four FRP channels.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
