The Component Method is well established and incorporated in Part 1.8 of Eurocode3 for the design of connections of steel frameworks. It is primarily intended to provide the elastic joint stiffness, although Part 1.8 includes provisions for also determining the inelastic moment-rotation response from the elastic limit to the ultimate moment. The latter provisions are empirical and use an established experimentally-based nonlinear equation to define the inelastic response. The Component Method has been further developed in recent years to determine the inelastic response using bi-linear springs with elastic and inelastic ranges. Procedures have also been developed at the University of Sydney to extend the Method into the post-ultimate range by defining tri-linear springs with elastic, inelastic and softening ranges. As well, recent research at the University of Sydney has produced a simple way to predict the moment-rotation response under fracture of components, thus enabling the Method to capture the full moment-rotation behaviour. The ability of the Method to predict full-range moment-rotation behaviour is especially useful for design by advanced analysis and progressive collapse analysis, as it allows both members and connections to be checked for stiffness and strength as part of the analysis. In parallel, an ongoing joint project between Sydney University and Tongji University on the strength of beam-to-upright connections in rack structures has extended to Component Method to cold-formed steel connections which include tang-connectors and bolts. The paper provides an overview of these recent developments of the Component Method, including the opportunity to incorporate the Method in a fully nonlinear procedure for the direct design of steel frameworks including connections by advanced analysis, also referred to as the Direct Design Method.

“…In order to predict the initial rotational stiffness of the beam-to-column connections used in cold-formed steel racks, Zhao et al [11] developed a corresponding mechanical model in 2017. The model was verified by experiments and the obtained results showed good agreement between the initial rotational stiffness given by the model and that recorded in the experimental results.…”

“…The behavior of the beam-to-column connections and the column bases has a major influence on the stability of rack structures [2][3][4][5][6][7][8][9][10][11][12]. Complex design details such as different mechanical devices used in beam-to-column connections (tabs and hooks without bolts and welds) do not allow the flexural behavior of the beam-to-column connections of steel storage racks to be easily predicted.…”

In practice, structures of pallet racks are characterized by very wide options of beam-to-column connections. The up to date part of the standard Eurocode 3 considers details for the design of connections. However, experimental determination of the joint properties in steel pallet racks is the most reliable process, since it takes into account an inability to develop a general analytical model for the design of these connections. In this paper, a test procedure for the behavior of beam-to-column connections is presented and the results are analyzed according to the procedure defined in the relevant design codes. With aim to avoid expensive experiments to determine structural properties of different types of connections, a polynomial model and a corresponding numerical model were developed to be used for simulating the experiment. After verification, the developed analytical and numerical model can be applied for investigation of various combinations of beam-to-column connections.

Steel pallet racking industry has globally used from the industrial revolution and has deeply evolved from hot-rolled profile into cold-formed profile to raise the optimization in engineering field. Nowadays, some studies regarding cold-formed steel profile have been performed, but fewer studies in terms of cold-formed pallet racking specifically in connection due to the semi-rigid behavior by lug-hooked into the upright have been conducted. The objective of this study is to review the related literature on steel storage racking connection behavior.
