Numerical Study on the Behavior and Design of Screw Connected Built-up CFS Chord Studs

This study presents the development and validation of a finite element modeling protocol in ABAQUS for screw connected, back-to-back built-up cold-formed steel (CFS) columns using results from experiments conducted at Johns Hopkins University. The goal is to examine the buckling, peak, and post-peak behavior (with an example shown in the figure) of built-up CFS columns of different cross section sizes and sheathing conditions, and under monotonic loading to improve existing built-up CFS column design guidelines so that all relevant failure modes are considered. Ongoing working includes cyclic collapse analyses, the characterization of chord stud buckling limit states, and a framework to implement these limit states in seismic simulations of CFS-framed shear walls.
