Section Properties For Cellular Decks Subjected To Negative Bending, Gregory L. Snow, W. Samuel Easterling Sep 2008

Section Properties For Cellular Decks Subjected To Negative Bending, Gregory L. Snow, W. Samuel Easterling

CCFSS Library (1939 - present)

Cellular decks are formed by attaching cold-formed “hat-shaped” deck sections on top of cold-formed steel sheets. The attachment is typically made using resistance spot welds spaced at a specific interval. The void left underneath the deck flutes and above the steel sheet provides a convenient means for the distribution of wiring and data cables throughout building systems. The section properties of cellular decks subjected to positive bending can be determined using the provisions of Chapter B of the 2001 AISI Specification (AISI, 2001). However, the provisions of Chapter B do not apply to cellular decks subjected to negative bending unless …


Innovative Composite Cold Formed Steel Floor Joist System, D. M. Fox, R. M. Schuster, M. Strickland Aug 2008

Innovative Composite Cold Formed Steel Floor Joist System, D. M. Fox, R. M. Schuster, M. Strickland

CCFSS Proceedings of International Specialty Conference on Cold-Formed Steel Structures (1971 - 2018)

Presented in this paper is a new, unique and innovative composite cold formed steel floor system developed by iSPAN Technologies, called the “iSPAN Composite Floor System”. The joist sections are fabricated by fastening two cold-rolled flange chord elements with cold-driven rivets to a flat web element. This makes it possible to create a section where the flange chord elements can be of a different steel thickness with respect to the web element, resulting in a most efficient structural cross section and numerous design alternatives. The joist sections have lip-reinforced web openings spaced at 4 ft o.c. along the joist length …

Vibration Performance Of Lightweight Floor Systems Supported By Cold-Formed Steel Joists, B. W. Davis, L. Xu Aug 2008

Vibration Performance Of Lightweight Floor Systems Supported By Cold-Formed Steel Joists, B. W. Davis, L. Xu

CCFSS Proceedings of International Specialty Conference on Cold-Formed Steel Structures (1971 - 2018)

A study investigating dynamic characteristics of full-scale floor systems was performed for several laboratory-constructed and in situ floors. Floors were constructed with cold-formed steel joists and designed for residential mid-rise applications. Typical construction details including span, subfloor, topping, strongback and framing condition were varied, and their influence on fundamental frequency, damping ratio and deflection at mid-span compared. Changes in construction details which significantly increased floor mass, regardless of added stiffness, were found to lower the fundamental frequency. Adding a strongback with restrained ends provided a significant increase in fundamental frequency, stiffness and damping ratio. Laboratory tested floor systems were generally …


Flexural Behavior And Design Of The New Built-Up Litesteel Beams, Sivapathasunderam Jeyaragan, Mahen Mahendran Aug 2008

Flexural Behavior And Design Of The New Built-Up Litesteel Beams, Sivapathasunderam Jeyaragan, Mahen Mahendran

CCFSS Proceedings of International Specialty Conference on Cold-Formed Steel Structures (1971 - 2018)

A new cold-formed steel beam, known as the LiteSteel Beam (LSB), has the potential to transform the low-rise building industry. The new beam is effectively a channel section with two rectangular hollow flanges and a slender web, and is manufactured using a simultaneous cold-forming and electric resistance welding process. Built-up LSB sections are expected to improve their flexural capacity and to increase their applications. They are also likely to mitigate the detrimental effects of lateral distortional buckling observed with single LSB members of intermediate spans. However, the behaviour of built-up beams is not well understood. Currently available design rules based …

Reinforcement Schemes For Cfs Joists Having Web Openings, K. Siva Sivakumaran Jun 2008

Reinforcement Schemes For Cfs Joists Having Web Openings, K. Siva Sivakumaran

American Iron and Steel Institute (AISI) Specifications, Standards, Manuals and Research Reports (1946 - present)

The Standard for Cold-Formed Steel Framing - Prescriptive Method for One and Two Family Dwellings, AISI S230-07, as well as other industry span and load tables are based on the standard web openings (i.e., punchouts), as defined in the North American Standard for Cold- Formed Steel Framing - Product Data, AISI S201-07. Presented in this report are the findings from an extensive testing program conducted at McMaster University on full-scale floor joists having larger web openings. Presented is an initial Final Report (86 pages) that was issued by the researcher in March 2007, as well as the results of Additional …


Strength Of Cold-Formed Steel Jamb Stud-To-Track Connections, A. Victor Lewis, Reinhold M. Schuster, Steven R. Fox Jun 2008

Strength Of Cold-Formed Steel Jamb Stud-To-Track Connections, A. Victor Lewis, Reinhold M. Schuster, Steven R. Fox

American Iron and Steel Institute (AISI) Specifications, Standards, Manuals and Research Reports (1946 - present)

The North American Standard for Cold-Formed Steel Framing - Wall Stud Design, AISI S211-07, provides a design expression for web crippling at the end reaction of the single stud-to-track connection. The subject of this report is an experimental investigation that was carried out at the University of Waterloo to establish a similar design expression for multiple jamb stud members. It is anticipated that the AISI Committee on Framing Standards will consider the results of this study in the development of future standards and the Cold-Formed Steel Engineers Institute in the development of design aids. The American Iron and Steel Institute …


Strength Of Arc-Spot Welds Made In Single And Multiple Steel Sheets, Gregory L. Snow, W. Samuel Easterling Jun 2008

Strength Of Arc-Spot Welds Made In Single And Multiple Steel Sheets, Gregory L. Snow, W. Samuel Easterling

CCFSS Library (1939 - present)

The objective of this research was to establish a relationship between arc spot weld shear strength and the arc time used to form the weld. Lap shear tests were performed on both 3/4 in. and 5/8 in. nominal diameter welds. Each weld was formed in one-, two-, or four-layers of sheet steel ranging from 22 gauge (0.028 in.) to 16 gauge (.057 in.). Three distinct time series were tested for each unique weld size, thickness of sheet steel and layer configuration. The first of these series were the full-time welds. The two remaining series, 2/3-time and 1/3-time welds, had arc …

A Fast Adaptive Wavelet Scheme In Rbf Collocation For Nearly Singular Potential Pdes, Nicolas Ali Libre, Arezoo Emdadi, Edward J. Kansa, Mohammad Shekarchi, Mohammad Rahimian Mar 2008

A Fast Adaptive Wavelet Scheme In Rbf Collocation For Nearly Singular Potential Pdes, Nicolas Ali Libre, Arezoo Emdadi, Edward J. Kansa, Mohammad Shekarchi, Mohammad Rahimian

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

We present a wavelet based adaptive scheme and investigate the efficiency of this scheme for solving nearly singular potential PDEs. Multiresolution wavelet analysis (MRWA) provides a firm mathematical foundation by projecting the solution of PDE onto a nested sequence of approximation spaces. The wavelet coefficients then were used as an estimation of the sensible regions for node adaptation. The proposed adaptation scheme requires negligible calculation time due to the existence of the fast DiscreteWavelet Transform (DWT). Certain aspects of the proposed adaptive scheme are discussed through numerical examples. It has been shown that the proposed adaptive scheme can detect the …
