Available in PDF, EPUB and Kindle. Book excerpt: Cold-formed steel sections are often used as wall studs or floor joists; such sections often include web holes for ease of installation of the services. Web crippling at points of concentrated, or localised, load or reaction in thin walled beams is well known to be a significant problem. Coldformed steel design codes, however, do not consider the effect of such web holes. In this thesis, a combination of experimental tests and non-linear elasto-plastic finite element analyses is used to investigate the effect of such holes on web crippling under two loading conditions interior-twoflange (ITF) and end-two-flange (ETF). The cases of both flange fastened and flange unfastened are considered. A good agreement between the experimental tests and finite element analyses is obtained in terms of both strength and failure modes. The finite element model is then used for the purpose of a parametric study on the effect of different sizes and position of holes in the web. It is demonstrated that the main factors influencing the web crippling strength are the ratio of the hole depth to the depth of the web, and the ratio of the distance from the edge of the bearing to the flat depth of web and the ratio of the length of bearing plates to the flat depth of the web. The web crippling strength without holes predicted from test and finite element analysis results are compared with the web crippling strength obtained from design codes. An extensive statistical analysis is carried out on web crippling strength of cold-formed steel sections with web holes. Design recommendations in the form of web crippling strength reduction factors are proposed, that are conservative to both the experimental and finite element results.

This book was released on 2019 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: Design guidance for web crippling behaviour of cold-formed stainless steel channel members that is given in the relevant design standards has been determined empirically from experimental studies and theoretical analyses. This guidance has been developed for cold-formed carbon steel members. Applying this design guidance to cold-formed stainless steel channel members based on carbon steel results is potentially inaccurate due to the very different stress-strain characteristics of stainless steel compared with that for carbon steel. These differences are principally in carbon steel having a clearly defined yield point, compared with stainless steel and in stainless steel having significant strain hardening when behaving inelastically compared with carbon steel. This means that new guidance must be developed for safe and efficient design of cold-formed stainless steel channels subject to web crippling. The primary objective of the research undertaken which is described in this thesis has been to develop design equations for web crippling of cold-formed ferritic stainless steel channels, with and without circular web perforations, under interior-one-flange, end-one-flange, interior-two-flange and end-two-flange loading. This involved first 216 laboratory tests, covering the cases of flanges restrained and unrestrained to the load or reaction plates. Finite element models were developed and validated against these tests and then used to expand the scope of the study with 3,600 finite element results. The finite element results use nonlinear quasi-static finite element analysis with an implicit integration scheme, which has advantages over static and quasi-static with an explicit integration scheme analyses. The laboratory and finite element results have been used to propose design rules that can be incorporated into design practice and design standards, and which make a distinction between flanges restrained and unrestrained to the load or reaction plates and address the presence of circular web perforations. Neither of these are currently covered in any design standards. The web crippling strengths for the flanges unrestrained and restrained cases were found to be either too conservative or unreliable, when compared to the provisions of stainless steel design standards. Web crippling design equations and strength reduction factors are proposed that are shown to be reliable and conservative when compared against laboratory and numerical results.

This book was released on 1984 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: "An extensive experimental investigation has been conducted to study the load-carrying capacity of cold-formed steel web elements subjected to partial edge loading which may cause web crippling or web buckling. In this experimental work emphasis was concentrated on the cold-formed steel structural members having single unreinforced webs with stiffened flanges. In 1980, American Iron and Steel Institute (AISI) revised its "Specification for the Design of Cold-Formed Steel Structural Members" For the design of beam webs, Section 3.5.1 of the AISI Specification provides the design criteria for web crippling. This thesis discusses the experimental work including some specimens with small length-to-depth ratios which may cause web buckling rather than web crippling. The failure mode for these specimens is beyond the scope of the current AISI Specification. Based on the results of tests conducted in this study, new design expressions have been developed to determine the critical web buckling load. Recommended design criteria are proposed for cold-formed steel structural members having single unreinforced webs with stiffened flanges"--Abstract, leaf ii.

Available in PDF, EPUB and Kindle. Book excerpt: "Experimental studies were performed to investigate the possible increase in the web crippling strength of cold-formed steel members when the flanges of the members were fastened to supports as opposed to member's flanges unfastened to supports. In this study channels, I-Sections, Z-Sections, long span roof decks (hat sections) and floor decks were investigated under two types of loading conditions, End-one-flange loading (EOF) and Interior-one-flange loading (IOF). The primary emphasis of this investigation was to determine if the current design criteria provided by the 1986 AISI Specification was underestimating the web crippling strength of these members, since the equations do not distinguish between fastened flanges and unfastened flanges. A review of past research concerning web-crippling strength of cold-formed steel members was performed and is discussed. The current design criteria of the 1986 AISI Specification and the 1986 Automotive Steel Design Manual regarding web crippling strength of cold-formed steel members is also discussed. Due to the fact that this was a pilot study, the number of tests performed for each type of member were limited. Therefore, there were no new equations developed, but based on the results some recommendations are made for future study"--Abstract, leaf iii.
