A theoretical model for the rotational stiffness of storage rack beam-to-upright connections

Experiments are generally used to investigate connection behaviour of steel storage racks, but the procedures are expensive and time-consuming. Various connections with complicated geometrical details necessitate simple and reliable design methods. This paper presents a mechanical model based on the component method to predict the initial rotational stiffness of beam-to-upright connections in cold-formed steel storage racks. In the model, five …
