The RMI (2008) and EN 15512 (2009) codes recommend that the material properties of pallet rack sections to be accurately determined by means of tensile coupon test.
Experimental and numerical results concerning the post-buckling behaviour and strength of fixed-ended cold-formed steel rack-section columns experiencing local distortional (L D) interaction are reported.
The work also includes a comparison between the ultimate strength and DSM design of lipped channel and rack-section columns undergoing similar L D interaction effects.
Then, experimental results available in the literature concerning lipped channel and rack-section columns failing in local distortional interactive modes are used to assess the quality of the estimates provided by the DSM-based design approaches.
It is shown that a novel DSM design approach, recently developed and validated in the context of cold-formed steel fixed-ended lipped channel columns affected by local distortional interaction, can also be successfully applied to hat, zed and rack-section columns under the same circumstances (i.e., exhibiting similar interactive failures).
The paper reports the results of a numerical investigation on the relevance of web-triggered local distortional interaction on the ultimate strength of a large number of cold-formed steel fixed-ended (plain) lipped channel, zed, hat and rack-section columns.
This paper reports the results of an investigation on the structural behaviour and Direct Strength Method (DSM) design of cold-formed steel columns affected by local distortional coupling interaction, aimed at extending findings unveiled earlier for lipped channels to other cross-section shapes, namely, hat, zed and rack-sections.
In the Rack Rates section, rates are shown in lire and the euro, with no currency converter in sight.
To prevent gear teeth jamming during rack-gear engagement, a rack-tilting mechanism was introduced to the rack part, which will be discussed in the next section.
These guys have probably seen it all together: watched emo rise from being a one-rack genre section in a Brighton record shop, to causing a nationwide moral panic, before fading back into nostalgic obscurity again.
