Calibration Of A Bending Model For Cold-Formed Sections, A. De Martino, A. Ghersi, Frederico M. Mazzolani
CCFSS Proceedings of International Specialty Conference on Cold-Formed Steel Structures (1971 - 2018)
The calibration procedure of a numerical model based on the simulation of the moment-curvature relation for cold-formed steel beams is presented. The results of bending tests on beams with double-channel cross-section are used to assess the proper values to the parameters which quantify the model.

Observations And Comments Pertaining To Can/Csa-S136-M89, Aaron S. Dinovitzer, Majid Sohrabpour, R. M. Schuster
CCFSS Proceedings of International Specialty Conference on Cold-Formed Steel Structures (1971 - 2018)
Contained in this paper are the results of two separate studies, namely, 1) partially stiffened compressive elements of both edge and single intermediate stiffened flanges and 2) deflection determination of multi-web deck profiles. Both of these studies were based on the Canadian cold formed steel design standard (CAN/CSA-S 136-M89), with the results also applicable to the AISI specification. In the case of partially stiffened compressive elements, discontinuities in effective width estimates for sections with similar flanges and stiffeners were observed, resulting from a sudden change in the behavioural states. Recommendations are presented to rectify this discontinuity and at the same …
Recent Developments In Cold Formed Steel, Robert W. Dannemann
Recent Developments In Cold Formed Steel, Robert W. Dannemann
CCFSS Proceedings of International Specialty Conference on Cold-Formed Steel Structures (1971 - 2018)
During the last fifteen years the author has been working in the development of new products in cold formed steel, mainly in building applications. Cold formed steel makes possible practically an infinite variety of shapes, one for each need and function. This possibility is a continuous challenge for designers in finding, among many alternatives, the optimal solution for each problem. The author describes briefly a set of six proposals, which are either an already tested and proven product, or just its phase of design. As in any human doing, the author is conscious that these proposals may be accomplished and …
The 1989 Edition Of The Canadian Cold Formed Steel Design Standard, R. M. Schuster
The 1989 Edition Of The Canadian Cold Formed Steel Design Standard, R. M. Schuster
CCFSS Proceedings of International Specialty Conference on Cold-Formed Steel Structures (1971 - 2018)
This paper presents excerpts from the latest edition of the Canadian Standard for the design of cold formed steel structural members (CAN/CSA-SI36-M89). Considerable technical changes, reflecting the latest research developments, have been incorporated into this edition of the Standard. These changes are based on an increased understanding of the behaviour of cold formed steel structures, members, and elements and of cold formed steel as a structural material. Some of the more significant technical changes of the Standard are discussed in greater detail. Comparisons with the Standard's predecessor (CAN3-S136-M84), and whenever appropriate, with the 1986 AISI Specifications are also made.
The Lateral Torsional Buckling Strength Of Cold-Formed Stainless Steel Lipped Channel Beams, P. Van Der Merwe, P. J. Bredenkamp, G. J. Van Den Berg
The Lateral Torsional Buckling Strength Of Cold-Formed Stainless Steel Lipped Channel Beams, P. Van Der Merwe, P. J. Bredenkamp, G. J. Van Den Berg
CCFSS Proceedings of International Specialty Conference on Cold-Formed Steel Structures (1971 - 2018)
The findings of an investigation into the lateral buckling strength of cold-formed singly-symmetric stainless steel beams are reported in this study. The singly-symmetric sections under consideration were lipped channel sections fabricated from a modified AISI stainless steel Type 409 designated 3CR12, a ferritic corrosion resisting steel. The purpose of this study was to compare the experimental strengths of singly-symmetric sections to the theoretical predictions proposed by the new ASCE Specification for the Design of Cold-Formed Stainless Steel Structural Members. It was concluded in this investigation that the tangent modulus approach adopted in the design specification for stainless steels, compared well …
Properties For Cellular Decks In Negative Bending, K. Balaji, Larry D. Luttrell
Properties For Cellular Decks In Negative Bending, K. Balaji, Larry D. Luttrell
CCFSS Proceedings of International Specialty Conference on Cold-Formed Steel Structures (1971 - 2018)
Cellular roof and floor decks may be formed by attaching essentially flat sheets to a "hat-shapes" or to fluted profiles by spot welding along the contact lines. This leads to a closed cellular deck unit suitable for such purposes as in-floor power distribution or communication systems. In positive bending, or when the flat sheet is in tension and stable, cellular deck flexural properties can be determined following the American Iron and Steel Institute Cold Formed Steel Design Manual. When the flat sheet is in compression, its contribution is not described in the AISI Manual since it is not continuously connected …
Design Of Channels Against Distortional Buckling, Y. B. Kwon, Gregory J. Hancock
Design Of Channels Against Distortional Buckling, Y. B. Kwon, Gregory J. Hancock
CCFSS Proceedings of International Specialty Conference on Cold-Formed Steel Structures (1971 - 2018)
Thin-walled lip-stiffened channel columns composed of high strength steel may fail in a distortional mode involving movement of the lip stiffener perpendicular to the flange plate it supports. In this report, test results for a simple lipped channel section(CH1) and an intermediate stiffened channel section (CH2) of thickness of approximately 1.1 mm (0.043 in) and 550 MPa (79.8 ksi) steel and undergoing distortional or mixed local-distortional buckling failure are compared with different design methods. The design methods compared are Australian Standard AS1538, EC3 Partl/ Annexe A, the ECCS Recommendations and the AISI Specification. In addition, new methods based on a …
Some Applications Of Generalized Beam Theory, J. Michael Davies, Philip Leach
Some Applications Of Generalized Beam Theory, J. Michael Davies, Philip Leach
CCFSS Proceedings of International Specialty Conference on Cold-Formed Steel Structures (1971 - 2018)
Generalised Beam Theory (GBT) has been developed by Professor R Schardt and his colleagues at the University of Darmstadt in Germany. The definitive reference at the present time is a recent German text(1) which describes the first-order theory. For the analysis of cold-formed sections, second-order theory may be required and this is less well documented. This paper will attempt to describe the principles involved and illustrate them by means of some practical examples. GBT unifies the conventional theories for the analysis of prismatic thin-walled structural members within a consistent notation. It then extends them into new territory. Conventional beam theory …

Racking Performance Of Plasterboard-Clad Steel Stud Walls, B. Golledge, T. Clayton, G. Reardon
CCFSS Proceedings of International Specialty Conference on Cold-Formed Steel Structures (1971 - 2018)
It is recognised that structural design efficiency in domestic and similar structures can be improved when the composite behaviour and contribution of all materials in the permanent structure can be fully recognised in the structural design of the frame. The ability to achieve this Improvement is currently limited by the need 10 rely on empirical test results for standardised building elements when considering the composite behaviour of the entire structure. The existing test methodology for determining the shear strength of plasterboard lined steel stud walls leads to an excessively conservative design of the complete structure. Since the test configuration is …
