Recent Situation of Cold Forming Rectangular Hollow Section Steel Columns in Buildings

Lateral-torsional buckling resistance of cold-formed high strength steel rectangular hollow beams

Hollow sections have been widely used for steel structures. Applications of High Strength Steel (HSS) on cold-formed hollow sections lead to thinner and lighter structures. This paper presents numerical investigations on the lateral-torsional buckling resistance of the cold-formed high strength steel rectangular hollow beam. Results from finite element analysis using Abaqus software are compare...

Cold End Forming Of Welded Steel Tubes

The production of custom and specific tube end shapes by cold end forming using a die is generally limited to seamless tubular parts. Current research work in the field follows the same trend as that of industry and, therefore, there is no accumulated experience, no practical design rules, and no information available in the specialized literature concerning the utilization of tube end forming ...

Bending Fatigue Tests and Finite Element Models of Steel Rectangular Hollow Sections [SRHS]

The Welding in cold formed areas is not only an open question for statically loaded sections (brittle fracture) but also for dynamically loaded structures (fatigue resistance). A lot of structures are subjected to dynamic loadings and unfortunately very little information about the influence of welding in the cold formed areas on fatigue resistance is available. In order to establish the fatigu...

Taylor-Aris dispersion in high aspect ratio columns of nearly rectangular cross section

We consider Taylor-Aris dispersion in columns of nearly rectangular cross section of large aspect ratio. We generalize the results of [1] and [2] who showed that the effective diffusion rate for perfectly rectangular cross sections is remarkably different than the diffusion rate between two parallel plates – as the aspect ratio goes to infinity, the effective diffusion rate does not approach th...
