This paper presents an experimental investigation of base connections fabricated from cold-formed channels and angle cleats. The finite element approach using the ANSYS software is used for the numerical analysis of the behavior of the base connections tested. A comparison between the finite element results and the experimental work results is presented. The use of bolted angle cleats allows a simple connection to be developed, this results in significant cost savings. Stiffer angle cleats are used to prevent premature failure of the base connections. The base connections are investigated under lateral horizontal load. In samples with smaller thickness of angle cleats, failure is mostly caused by premature deformation of the angle cleats. On the other hand, base connections with bigger thickness of angle cleats are so stiff that failure mainly occurred in the column channels. A significant amount of bearing distortion is observed in the heavily loaded flange.
