Abstract
The proposed study analyze the structuralperformances of built-up columns made by open FRP (fiberreinforced polymer) profiles. These open profiles are connectedto each other and each column has two typologies of connection:the first guarantees the junction between the two channel- weband the second one assures the connection between thebuilt-up-web and the external flanges. Specifically, the researchverify the influence of the anisotropy of the material and theshear deformability as well as the interaction between local andglobal buckling on the overall bearing capacity of the assembledcolumn. The analyzed case regards a built-up column made byfour FRP channels made by pultrusion process and connectedalong the column with steel bolts. The study proposes both anumerical and experimental analysis. The comparison betweenthese, aims to better fit particularly the influence of shear and todetermine the local mechanisms of diffusion and the load’sdistribution through the bolted connection and the four FRPchannels.
