Steel fabricators and connection designers in the building construction industry often rely on traditional connection design methods, which involve using connection design software or spreadsheets to simulate and design connections with the goal of minimizing costs associated with fabrication and...

20Cr-32Ni-1Nb stainless steel alloys are commonly used in hydrogen reformer manifolds for transporting hot hydrogen by-products at 750-950 celcius. After long periods of exposure, embrittling secondary carbides and intermetallic phases can precipitate at the grain boundaries which can drastically...

Residual stresses can have a significant impact on the stability of structural members. In the case of I-section beam elements, such stresses can impact lateral--torsional buckling (LTB) capacity, particularly in the inelastic range. I-sections are typically fabricated by either rolling as a...

It has become common for steel fabricators to find torsional loads included in the design documents of many industrial steel structures. These loads arise in wide-flange beam-to-column moment connections when the beam is subject to weak axis bending, which in turn, is transferred to the column as...

Modularization of buildings comes in several types, from prefabricated members to full volumetric models. Recently, the introduction of modular construction methods brought numerous benefits to the construction industry. Reducing construction time and costs together with improving quality and...

Effects of Submerged Arc Weld (SAW) Parameters on Bead Geometry and Notch-Toughness for X70 and X80 Linepipe Steels
DownloadFall 2009
For the manufacture of higher strength pipelines to be feasible, a better understanding of the effects of welding on toughness is necessary. Bevel submerged arc welds were performed on X80 grade steel. The subsequent Charpy V-notch (CVN) test results indicated that the notch placement in the...

Extracting and Integrating Industrial Construction Steel Trade Data in ill-formed BIM Models
DownloadFall 2017
Oil and gas are known for their huge-size and complex projects that consist of multiple trades’ subprojects such as concrete, steel, and piping. These subprojects are executed within a confined area during a limited time frame. This requires careful planning and coordination between these...

Coped beams are susceptible to fatigue cracking in the web at the cope radius when subjected to tension in the coped region. Use of an adhesively bonded composite patch over the crack can reduce the stress concentration and delay further crack growth. This report contains the results of a...

Finite Element Model of the Thermal Profile During Submerged Arc Welding with One and Two Electrodes
DownloadFall 2016
The submerged-arc welding (SAW) process is used extensively in the manufacturing of pipes. The heat flow introduced by the welding operation has a significant impact on the properties of both the weld metal and the heat affected zone (HAZ). The work presented in this thesis aims to develop a...

Casing pipes used in sour service are prone to two forms of failure: hydrogen induced cracking (HIC) and sulfide stress cracking (SSC). The objective of this thesis is to investigate the resistance of L80 ERW and Seamless steel pipe, with five different chemical compositions, to both HIC and SSC....
