Finite Element Modelling of Cold Formed Stainless Steel Columns

Structural behavior of cold-formed stainless steel bolted connections

This paper presents a series of tests on cold-formed stainless steel bolted connections. The test specimens were fabricated from three different types of stainless steel, including austenitic stainless steel EN1.4301 (AISI 304) and EN1.4571 (AISI 316Ti having small amount of titanium) as well as lean duplex stainless steel EN1.4162 (AISI S32101). The material properties of the three types of st...

Finite Element Analysis on Tensile Stiffness of Cold-Formed Steel Bolted Connections

This paper presents a finite element analysis on the tensile stiffness of steel bolted connections, which are fabricated from thin-walled cold-formed steel strips and members. This type of bolted connection is usually used to assemble the diagonal bracing member in the light steel structure. Unlike the architectural steel structure, thin walled steel bolted connection cannot be simplified into ...

On Cold-Formed Steel Construction

Powder-actuated (also referred to as low velocity or powder-driven) fasteners are commonly used to attach cold-formed steel framing members, usually a track, to a concrete or structural steel support. Although commonly used, their behavior is less well understood than other fasteners such as screws, bolts and welds. The AISI Cold-Formed Steel Design Manual does not explicitly address powder act...

Computational Modeling of Cold-formed Steel

The objective of this paper is to summarize recent research and experiences with computational modeling of cold-formed steel conducted within the author’s research group at Johns Hopkins University. This admittedly biased view of computational modeling focuses primarily on the use of the semi-analytical finite strip method and collapse modeling using shell finite elements. Issues addressed incl...
