This book was released on 1989 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The allowable stress design (ASD) method has long been used for the design of steel structures in the United States. Recently, the probability-based load and resistance factor design (LRFD) criteria have been successfully applied to the structural design of hot-rolled steel shapes and built-up members. The AISI LRFD Specification is being developed as well for the design of structural members cold-formed from carbon and low alloy steels. This design method is based on the "Limit States Design" philosophy, which is related to the ultimate strength and serviceability of the structural members and connections. Cold-formed stainless steel sections have gained increasing use in architectural and structural applications in recent years due to their superior corrosion resistance, ease of maintenance, and attractive appearance. The current Specification for the design of cold-formed stainless steel structural members and connections was published by American Iron and Steel Institute (AISI) in 1974. This design Specification was based on the allowable stress design method. In order to develop the new design criteria for cold-formed stainless steel structural members, a research project entitled "Load and Resistance Factor Design of Cold-Formed Stainless Steel" has been conducted at the University of Missouri-Rolla. This project contains two phases: (1) to prepare an updated allowable stress design specification and (2) to develop the new load and resistance factor design criteria for cold-formed stainless steel structural members and connections. The proposed new ASD Specification and Commentary for the design of cold-formed stainless steel structural members have been completed and published in the Third Progress Report of this project. This dissertation mainly discusses the development of the LRFD criteria for cold-formed stainless steel structural members and connections. These design criteria were developed on the basis of the first order probabilistic theory, for which only the mean value and coefficient of variation of variables are required. These variables reflect the uncertainties in mechanical properties of materials, load effects, design assumption, and fabrication. As the initial step of the investigation, statistical analyses of mechanical properties and thicknesses for various types of stainless steels have been evaluated. The modified Ramberg-Osgood equation has been used in this study for determining the secant modulus, tangent modulus, and plasticity reduction factor. Theoretical basis of the probability-based LRFD criteria and procedures used to calibrate the design provisions are discussed in detail. The resistance factors obtained from the calibrations have been recommended for use in the LRFD criteria. Because the LRFD method involves probabilistic considerations for uncertain variables in the design formulas, this method can provide a more uniform overall safety and reliability for structural design"--Abstract, pages ii-iii.

This book was released on 1987 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This dissertation describes the development of the basic criteria needed for the design of structural members cold-formed from certain ferritic stainless steels. The Allowable Stress Design method as well as the Load and Resistance Factor Design method receive attention. The ferritic stainless steels under consideration are: Types AISI 409 and 430 as well as a modified Type 409 steel, designated 3CR12 steel, developed and produced by the speciality steel producing company, Middelburg Steel and Alloys in South Africa. The mechanical properties needed for structural design are established. It is shown through an experimental study that the design provisions for the carbon and low-alloy steels as well as those for the austenitic stainless steels, are suitable for the ferritic stainless steels in as far as local and post buckling behavior of flat stiffened and unstiffened compression elements of member sections are concerned. Investigations into the behavior of flexural members and axially loaded compression members indicate that aspects such as ultimate moment capacity and deflection of flexural members and overall column buckling of compression members may be predicted with confidence. The performances of bolted and welded connections are also evaluated. The experimental results are statistically analyzed to provide the information required for the development of resistance factors for the Load and Resistance Factor Design Method. The needs for future research are identified"--Abstract, leaf ii.

Book excerpt: The purpose of this project was to: 1) study deformation twinning, its evolution, thermal stability, and the contribution on mechanical response of the new advanced stainless steels, especially at elevated temperatures; 2) study alumina-scale formation on the surface, as an alternative for conventional chromium oxide, that shows better oxidation resistance, through alloy design; and 3) design new generation of high temperature stainless steels that form alumina scale and have thermally stable nano-twins. The work involved few baseline alloys for investigating the twin formation under tensile loading, thermal stability of these twins, and the role of deformation twins on the mechanical response of the alloys. These baseline alloys included Hadfield Steel (Fe-13Mn-1C), 316, 316L and 316N stainless steels. Another baseline alloy was studied for alumina-scale formation investigations. Hadfield steel showed twinning but undesired second phases formed at higher temperatures. 316N stainless steel did not show signs of deformation twinning. Conventional 316 stainless steel demonstrated extensive deformation twinning at room temperature. Investigations on this alloy, both in single crystalline and polycrystalline forms, showed that deformation twins evolve in a hierarchical manner, consisting of micron-sized bundles of nano-twins. The width of nano-twins stays almost constant as the extent of strain increases, but the width and number of the bundles increase with increasing strain. A systematic thermomechanical cycling study showed that the twins were stable at temperatures as high as 900°C, after the dislocations are annealed out. Using such cycles, volume fraction of the thermally stable deformation twins were increased up to 40% in 316 stainless steel. Using computational thermodynamics and kinetics calculations, we designed two generations of advanced austenitic stainless steels. In the first generation, Alloy 1, which had been proposed as an alumina-forming austenitic stainless steel, is fully austenitic, but possesses carbides that were not dissolvable and could not be controlled. This alloy also did not show deformation twinning. Alloy 2 was designed based on alloy 1, but was not fully austenitic and had significant traces of uncontrollable precipitates as well. Alloy 3, also designed based on alloy 1, was mainly austenitic with evolution of a second phase along the grain boundaries, but also had precipitates that were not controllable. Based on the knowledge gained from the first generation of the designed steels, two more steels, called PGAA1 and PGAA2, were proposed using genetic algorithms that, based on the modelling, were supposed to exhibit alumina-scale formation. PGAA1, however, did not demonstrate a fully austenitic structure. PGAA2 could achieve a mostly austenitic structure through thermo-mechanical processing, and was then used for oxidation tests. The oxidation tests of PGAA2, with and without nitrogen impurities, along with alloy 1, suggested that PGAA2 can form alumina-scale similar to alloy 1, but N impurity will prevent formation of such a scale, probably through formation of aluminum nitrides. For the above mentioned genetic algorithm framework of alloy design, separate models were developed for specific design criteria. For prediction of alumina formation in stainless steels, a model was constructed based off of two criteria - effective valence and third element effect. These criteria capture the thermodynamics and kinetics of alumina formation in steels. To test the efficacy and robustness of this model, they were tested against alloys in the literature which had been experimentally verified to exhibit alumina formation and the predictions were in excellent agreement with the experiments. Another meta-model for prediction of twinning in unknown steel compositions was developed by an informatics based machine learning/data mining approach. Stacking Fault Energy data was captured from the literature for a l ...

Available in PDF, EPUB and Kindle. Book excerpt: Stainless steel is increasingly used in construction due to its corrosion resistance, ease of maintenance, aesthetics and fire resistance. In spite of these benefits, its application in structures has been inhibited by a lack of design guidance that makes optimum use of its properties. An extensive test programme was carried out on structural members and connections in stainless steel. The project concentrated on the most commonly used austenitic grades 1.4301 and 1.4401 and one duplex grade, 1.4462. One work package studied ferritic grades. Numerical models were calibrated against these test results, and then used to analyse the effects of a wider range of parameters than those tested. The existing design rules in the Eurocode covering design of structural stainless steel, ENV 1993-1-4, were compared against the experimental and numerical data. Where the rules proved excessively conservative, more economic design rules were developed. The results of the project will lead to both revision and addition to the existing guidance in ENV 1993-1-4 as well as ENV 1993-1-2, the Eurocode covering design of structures in fire. Key recommandations include : - less severe limiting width-to-thickness ratios for welded flanges and webs in compression, webs subject to bending and circular hollow sections subject to bending; - less severe buckling curves for major axis flexural buckling and lateral torsional buckling of welded I-sections; - a new design approach for shear buckling and web crippling, closely based on the ENV 1993-1-5 rules; - a method for predicting the fire resistance of beams and columns.
