Semi-rigid composite frames with perfobond and T-rib connectors Part 1: Full scale tests

This paper proposes an alternative construction system for composite portal frames. The proposed process uses a perfobond rib shear connector and a connection element, denominated “T-rib” for composite action. The “T-rib” connection element was developed with the aim of transferring the forces from the reinforcing bars, used in hogging moment regions, to edge and corner column flanges. Full-scale test results of a composite semi-rigid portal frame are presented in terms of load–deflection, load–deformation and load–rotation curves.
