Book excerpt: "It is well-known that the current AlSI Specification for the design of cold-formed steel structural members has been developed mainly for thin steel sections. In order to extend the applicability of the specification for the design of cold-formed steel members thicker than 1/4 in., both analytical and experimental investigations have recently been conducted with special emphases on the effects of cold work on the mechanical properties of corners and the strength of bolted connections. For the effects of cold work, previous investigations have shown that the phenomena of strain hardening and strain aging are main factors which affect the mechanical properties of corners. The yield point and ultimate tensile strength of corners are larger than those in virgin steels, and the ductility of virgin steels will be decreased as a corner is formed. Mathematical corner models developed by other investigators for the prediction of tensile yield points of corners were studied in detail. It was found that the increase in yield point of corners is dependent upon the ratio of virgin ultimate tensile strength to virgin tensile yield point, the ratio of inside bend radius to the thickness of the corner, and the virgin tensile yield point. In order to study the possible effects of thickness on the mechanical properties of corners, a total of one hundred corner tests have been conducted. The corner specimens used in the test program were cold-formed from 1/2 in. and 1 in. thick A36 and A588 steel plates with R/t ratios of 3, 5 and 6. On the basis of the test data obtained from the recent study and previous investigations, it was found that in addition to the above-mentioned three factors, the increase in yield point of corners also depends on the type of stress-strain curves of virgin steels, but is not directly affected by the thickness of corners. Consequently, modified equations were derived on the basis of a regression analysis which can be alternatively used for the determination of tensile yield point of corners, when the virgin steel has a sharp yielding type of stress-strain curve with a large plateau. In view of the fact that sharp yielding type of stress-strain curves is usually found for hot-rolled steels, and gradual yielding type of stress-strain curves is found for cold-reduced steels, the current AISI formulas can be used for cold-reduced steels and other steels having a sharp yielding type of stress-strain curve with a small plateau. It has been realized that the AISC Specification is primarily developed for the design of thick, hot-rolled steel members. Studies of the strength of bolted connections made of thick, cold-formed steel members were, thus, conducted mainly by comparing the AISI and AISC Specifications. Other specifications, recommendations, and standards being used abroad and the research work carried out at other universities were also reviewed and considered. From a study of design criteria for bolted connections listed in various specifications, it was found that the main difference for the design of bolted connections made of thin and thick steels is the allowable bearing stress and the related, required edge distance in line of stress. In order to study further the bearing capacity of bolted connections, a total of thirty single-shear and double-shear bolted connections were tested. The test specimens were fabricated from A36 and A570 steels with thicknesses of 11 ga., 3/16 in., and 1/4 in. From a thorough analysis of the available results of connection tests, two modified design equations were derived for the determination of the minimum edge distance in line of stress and allowable bearing stress using ordinary bolts. These modified equations not only apply to steels with various ductilities, but also close the gap between the AISI and AISC Specifications for allowable bearing stress. These equations also provide a conservative basis for the design of bolted connections using high-strength bolts. For purposes of design, simplified equations were also developed and recommended for the minimum edge distance and allowable bearing stress. With regard to other design requirements for bolted connections, such as allowable tension stress on net section and allowable shear stress on bolts, the current AISI design criteria can also be used for connections made of thick, cold-formed steel members "--Abstract, pages ii-iv.

This book was released on 1972 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Analytical and experimental investigations have been conducted to study the influence of perforations on the structural behavior of cold-formed steel structural members. Since in many cases, the load-carrying capacity of cold-formed steel members depends on the buckling behavior of individual component elements, emphasis has been concentrated on the study of the instability and post-buckling strength of perforated elements. In this investigation, the buckling loads and post-buckling strength of stiffened and unstiffened compression elements having single circular and square holes have been studied analytically by using the finite element method. The effects of different holes on the buckling coefficient have been verified by the experimental data obtained from the testing of columns and beams with perforated flanges. The equations for determination of the effective width have been developed on the basis of the post-buckling strength of compression elements. An experimental investigation has been conducted to study the influence of holes on the shear buckling load of beam webs. The test data was compared with analytical results of other investigators. Better correlation was found between the test data and the analytical solution for the simple support condition. A load reduction equation was derived on the basis of the experimental study. The crippling strength of perforated webs were also investigated experimentally. In this investigation, twenty tests were conducted to cover a practical range of height-to-thickness ratios. Based on the results obtained from tests, load reduction factors were derived for steel members with circular and square perforated webs. The stability of perforated plates subjected to equal and opposite point loads were investigated. The trend of this analytic study was found in agreement with the experimental investigation. Design recommendations are developed for: perforated stiffened compression elements, perforated unstiffened compression elements, perforated shear webs, and crippling of perforated webs"--Abstract, pages ii-iii.

Book excerpt: Thin-plated structures are used extensively in building construction, automobile, aircraft, shipbuilding and other industries because of a number of favourable factors such as high strength-weight ratio, development of new materials and processes and the availability of efficient analytical methods. This class of structure is made by joining thin plates together at their edges and they rely for their rigidity and strength upon the tremendous stiffness and load-carrying capacity of the flat plates from which they are made. Many of the problems encountered in these structures arise because of the effects of local buckling. The knowledge of various facets of this phenomenon has increased dramatically since the 1960s. Problem areas which were hitherto either too complex for rigorous analysis or whose subtleties were not fully realized have in these years been subjected to intensive study. Great advances have been made in the areas of inelastic buckling. The growth in use of lightweight strong materials, such as fibre-reinforced plastics has also been a contributory factor towards the need for advances in the knowledge of the far post-buckling range. The conference is a sequel to the international conference organised by the University of Strathclyde in December 1996 and this international gathering will provide the opportunity for discussion of recent developments and trends in design of thin-walled structures.
