Stress concentration factors of cold-formed stainless steel tubular X-joints

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...

distribution of stress concentration factors along the weld toe of tubular kt-joints in truss bridges

many research works have been accomplished so far on the computation of stress concentration factors (scfs) for various types of tubular joints. almost all these studies have focused on values of the scf at the saddle and crown positions, and they have ignored the hss at other locations along weld toe. however, scf distribution is very important for predicting the fatigue crack growth, determin...

Stress Concentration Factors in Uniplanar Tubular KT-Joints of Jacket Structures Subjected to In-Plane Bending Loads

In the present research, data extracted from the stress analysis of 46 finite element models, verified using test results obtained from an experimental investigation, were used to study the effect of geometrical parameters on the chord-side stress concentration factors (SCFs) of central and outer braces in uniplanar tubular KT-joints of offshore structures subjected to four different types of i...

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...
