—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
