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 …

Influence Of Deformed Metal Decking Composite Floors To Beam-Column Connections, Y. Xiao, D. A. Nethercot, B. S. Choo
Influence Of Deformed Metal Decking Composite Floors To Beam-Column Connections, Y. Xiao, D. A. Nethercot, B. S. Choo
CCFSS Proceedings of International Specialty Conference on Cold-Formed Steel Structures (1971 - 2018)
A series of tests designed to investigate the interaction of a variety of different steel beam to column connection details with a composite metal deck floor is described. The main emphasis is on assessing the connections' moment capacity, rotational stiffness and rotation capacity. The full details of the experimental behaviour of the flush end plate and partial depth end plate connections will be described in this paper. A simple method for moment capacity calculation based on the test results is proposed herein.
Behavior Of Arc Spot Weld Connections In Tension, Roger A. Laboube, Wei-Wen Yu
Behavior Of Arc Spot Weld Connections In Tension, Roger A. Laboube, Wei-Wen Yu
CCFSS Proceedings of International Specialty Conference on Cold-Formed Steel Structures (1971 - 2018)
A comprehensive experimental study of the tension strength of arc spot weld connections, that affix a cold-formed steel roof deck to its support member, was conducted. Based on the experimental results obtained from over 260 connection tests, equations have been developed that predict the tension capacity of an arc spot weld connection. These equations are easily applied, and lend themselves to use by structural designers.

Activities Of The Center For Cold-Formed Steel Structures, Wei-Wen Yu, Roger A. Laboube
CCFSS Proceedings of International Specialty Conference on Cold-Formed Steel Structures (1971 - 2018)
The Center for Cold-Formed Steel Structures was established at the University of Missouri-Rolla in May 1990 under the sponsorship of the American Iron and Steel Institute and the University of Missouri-Rolla. This paper summarizes the activities performed at the Center during the past two years.
New Asce Standards For Cold-Formed Steel Deck Slabs, Max L. Porter
New Asce Standards For Cold-Formed Steel Deck Slabs, Max L. Porter
CCFSS Proceedings of International Specialty Conference on Cold-Formed Steel Structures (1971 - 2018)
This paper presents highlights of the newly approved and printed ASCE Standard on the design and construction of composite floor deck slabs utilizing cold-formed steel. In 1992 four documents are being published including the following: • "Standard for the Structural Design of Composite Slabs"--ASCE3-92, • "Standard Practice for Construction and Inspection of Composite Slabs"-ASCE9-92, and • A separate commentary on each of the two above Standards. These above four documents stem from a previously published ASCE Standard entitled "Specifications for the Design and Construction of Composite Slabs" and the associated commentary thereon. The Steel Deck with Concrete Committee of the …

Thermal Shielding Near Intermediate Supports Of Continuous Span Composite Slabs, Kees Both, Leen Twilt, Jan W. B. Stark
CCFSS Proceedings of International Specialty Conference on Cold-Formed Steel Structures (1971 - 2018)
At TNO Building and Construction Research, in close co-operation with the Eindhoven University of Technology, research is carried out on the behaviour of fire-exposed composite steel/concrete slabs, in the framework of a research project co-sponsored by the ECSC (European Community for Steel and Coal). The paper describes the state of the art of the research project.

Distortional Buckling Of Cold-Formed Steel Z-Section Columns, P. Charnvarnichborikarn, Dimos Polyzois
CCFSS Proceedings of International Specialty Conference on Cold-Formed Steel Structures (1971 - 2018)
Current North American guidelines for the design of cold-formed steel members consider the web of cold-formed steel sections under direct compression to be a fully stiffened element. This, however, may not be true if the flanges cannot provide sufficient restraint to the web. In this case, instability of the web element may cause distortional failure of the flange-edge stiffener component which may limit the load-carrying capacity of these sections with very little post-buckling strength being realized. In the present paper, the effect of web buckling on the load-carrying capacity of Z-sections with partially stiffened flanges is examined. The current design …
