A Design Approach For Complex Stiffeners, Andrew T. Sarawit, Teoman Pekoz

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

This paper presents a design approach for laterally braced cold-formed steel flexural members with edge stiffened flanges other then simple lips. The design method for flexural members given by Schafer and Pekoz (1999) is used here for designing these complex stiffeners. The method integrates distortional buckling into the unified effective width approach currently used in most cold-formed steel design specifications. A finite element method was first used to investigate the post-buckling behavior and carry out initial geometric imperfection sensitivity studies for various types of stiffeners. Then parametric studies were carried out for different types of stiffeners to compare the moment …

Cyclic Pull-Out Strength Of Steel Roof And Wall Cladding Systems, Mahen Mahendran, Dhammika Mahaarachchi

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

When crest-fixed thin steel roof cladding systems are subjected to wind uplift, local pull-through or pull-out failures occur prematurely at their screwed connections. During high wind events such as storms and cyclones these localised failures then lead to severe damage to buildings and their contents. In recent times, the use of thin steel battens/purlins has increased considerably. This has made the pull-out failures more critical in the design of steel cladding systems. Recent research has developed a design formula for the static pull-out strength of steel cladding systems. However, the effects of fluctuating wind uplift loading that occurs during high …

Knee Joints In Cold-Formed Channel Portal Frames, Julie Mills

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

Light gauge cold-formed channel sections are frequently used in portal frame construction for small span agricultural and industrial sheds. A testing program at the University of South Australia has shown that the knee joint currently used in these sheds fails at bending moments well below required design values. An alternative joint construction using multiple Teks screws is being developed and is exhibiting much better performance.

Pull-Through Failures Of Crest-Fixed Steel Claddings Initiated By Transverse Splitting, Dhammika Mahaarachchi, Mahen Mahendran

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

Crest-fixed steel claddings made of thin, high strength steel often suffer from local pull-through failures at their screw connections during high wind events such as storms and hurricanes. Currently there aren't any adequate design provisions for these cladding systems except for the expensive testing provisions. Since the local pull-through failures in the less ductile steel claddings are initiated by transverse splitting at the fastener hole, analytical studies have not been able to determine the pull-through failure loads. Analytical studies could be used if a reliable splitting criterion is available. Therefore a series of two-span cladding tests was conducted on a …

Lateral Strength Of Wind Load Bearing Wall Stud-To-Track Connection, R. M. Schuster, S. R. Fox

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

A common application of cold formed steel in building construction is for wind load bearing steel studs (curtain walls). These wall studs are designed to carry lateral load only, and frame into horizontal steel track members at the top and bottom of the wall assembly. The stud-to-track connection consists of studs framing perpendicularly into the track and are connected with sheet metal screws. The design of the wall stud must include a check of the web crippling capacity at the end reactions. The current design expressions, however, do not apply to the type of bearing in these stud-to-track connections. Reported …

Tests And Design Of Cold-Formed Unlipped Channels Subjected To Web Crippling, Ben Young, Gregory J. Hancock

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

A series of tests on cold-formed unlipped channels subjected to web crippling is presented in this paper. The tests were conducted under the four loading conditions specified in the Australian/New Zealand Standard (AS/NZS 4600, 1996) and the American Iron and Steel Institute (AISI, 1996) Specification for cold-formed steel structures. The four specified loading conditions are the End-One-Flange (EOF), Interior-One-Flange (IOF), End-Two-Flange (ETF) and Interior-Two-Flange (ITF) loading. The loading of concentrated load or reaction forces were applied by means of bearing plates which acted across the full flange widths of the channels. The web slenderness values of the tested channel sections …

Web Crippling Behaviour Of Channels With Flanges Restrained, Ben Young, Gregory J. Hancock

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

The paper presents a comparison of web crippling tests of cold-formed unlipped channels with flanges restrained or unrestrained. The tests were performed under end and interior two-flange loading conditions specified in the Australian/New Zealand Standard (AS/NZS 4600, 1996) and the American Iron and Steel Institute (AISI, 1996) Specification for cold-formed steel structures, namely End-Two-Flange (ETF) and Interior-Two-Flange (ITF) loading conditions. The concentrated load was applied by a bearing plate at the top flange of the channels, and the reaction force applied by an identical bearing plate at the bottom flange of the channels. The bearing plates acted across the full …

A Theoretical And Experimental Analysis Of Cold-Formed Steel Shapes Subjected To Bending - Channel And Simple Lipped Channel, Roberto Martins Goncalves, Maximiliano Malite, Carlos Eduardo Javaroni

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

Cold-formed steel shapes have been widely employed in steel construction, where they frequently offer a lower cost solution than do traditional laminated shapes. A classic application of cold-formed steel shapes is purlins in the roof panel of industrial buildings, connected to the roof panel by means of screws. The combined effect of these two elements has been the subject of investigations in some countries. Design criteria were included in the AISI Code in 1991 and 1996. This paper presents and discusses the results obtained from bending tests carried out on shapes commonly used in Brazil, i.e., the channel and the …

Calibration Of Cold Formed Steel Shear Equations, B. Craig, R. M. Schuster

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

There is a difference in the shear design criteria between the Canadian cold formed steel design Standard, CSA S136-94 (from here on referred to as S136) and the American Iron and Steel Institute Specification for the design of cold formed steel structures, AISI-96 (from here on referred to as AISI). The focus of this paper was to carry out the appropriate calibrations for the factor of safety, Ω, and the resistance factor, Ï•, using the current design approaches of both countries. In the case of the S136 Standard, only the resistance factor was determined. It was assumed at the outset …

Elastic-Plastic Interactive Buckling Of Thin-Walled Steel Compression Members, Dan Dubina, Viorel Ungureanu

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

In the actual design codes the interaction formula for local and overall buckling modes of thin-walled steel compression (TWSC) members, the effect of local buckling. is introduced by means of effective strength of short members. This paper proposes to replace, into the Ayrton-Perry interaction formula, the short member "effective" strength, which is based on the "effective width" approach by the plastic strength evaluated by means of local plastic mechanism analysis. There are some papers by Murray et al. [1,2,3], in which the plastic mechanisms corresponding to the local buckling of plates and TWSC members in compression are analysed. On this …

Finite Element Analysis Of Cold-Formed Channel Columns, Ben Young, Jintang Yan

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

The paper presents a numerical investigation into the behaviour and strengths of cold-formed plain and lipped channel columns using finite element analysis. A non-linear finite element model is developed and verified against the fixed-ended channel column tests conducted by Young and Rasmussen (1998a, 1998b and 1998c). Geometric and material non-linearities were included in the finite element model. It is demonstrated that the finite element model closely predicted the ultimate loads and the behaviour of the tested cold-formed channel columns. Hence, the model was used for an extensive parametric study of cross-section geometries. Furthermore, the results of the numerical investigation are …

Purlin Design To Aisi Lrfd Using Rational Buckling Analysis, Murry J. Clarke, Gregory J. Hancock

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

The latest edition of the American Iron and Steel Institute (AISI) Specification for the Design of Cold-Formed Steel Structural Members was published in 1996 (AISI, 1996). Design rules are presented in both allowable stress design (ASD) and load and resistance factor design (LRFD) formats. The LRFD rules of the latest AISI Specification form the basis of the Australian/New Zealand Standard AS/NZS 4600:1996 Cold-Formed Steel Structures (SA/SNZ, 1996), which was published in late 1996 and supersedes the corresponding Australian permissible stress Standard AS 1538-1988. One of the main applications of cold-formed steel is purlins and girts in metal roof and wall …

Racking Performance Of Long Steel-Frame Shear Walls, Alexander J. Salenikovich, Daniel J. Dolan, Samuel W. Easterling

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

The response of cold-formed steel-frame shear walls to lateral forces is the focus of the paper. Results are presented for monotonic and cyclic tests of sixteen full-size shear walls with and without openings. Walls of five configurations with sheathing area ratio ranging from 1.0 to 0.3 were tested. The specimens were 12-m (40-ft.) long and 2.4-m (8-ft.) high with 11-mm (7/16-in.) oriented strandboard (OSB) sheathing. One specimen had additional 13-mm (0.5-in.) gypsum wallboard sheathing. All specimens were tested in horizontal position with no dead load applied in the plane of the wall. Resistance of walls was compared with predictions of …

Flexural Behavior Of Profiled Composite Beams, Jun-Yep Song, Young Bong Kwon

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

The behavior of composite beams, which are composed of cold-formed steel sheeting and normal strength concrete, has been studied. A series of flexural tests of composite beams has been executed and analytical methods to trace the nonlinear behavior of composite beams have been developed. The nonlinear moment-curvature relation of the composite beam has been described using a simple power model and cross section analysis procedure. The load-deflection behavior of the composite beam simulated by the step-by-step numerical integration method has been compared with test results.

The 1999 Supplement To The Aisi Design Specification, Roger L. Brockenbrough

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

The AISI Committee on Specifications for Cold-Formed Steel recently developed Supplement No. 1 to the 1996 Specification for the Design of Cold-Formed Steel Structural Members. The Supplement reflects new information developed through research projects, brings provisions in agreement with other specifications where appropriate, and also provides certain clarifications and corrections. The Supplement and the Specification have both been recently accepted as ANSI standards. The present paper reviews the major items included in the Supplement. The Committee continues to sponsor research projects aimed at developing a better understanding of particular areas of cold-formed steel behavior and more comprehensive design rules. Projects …

Yield Strength Increase Of Cold Formed Sections Due To Cold Work Of Forming, P. A. Sloof, R. M. Schuster

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

The design approach for predicting the increase in yield strength due to cold work of forming in the AISI 1996 Specification for the Design of Cold-Formed Steel Structural members is different from the approach used by the CSA Standard, CSA S136-94, Cold Formed Steel Structural Members. The AISI approach is based on the experimental work conducted by Karren and Winter, while the S136 approach is based on theoretical work by Lind and Schroff. Lind and Schroff used Karren and Winter's data to substantiate their theory. Karren and Winter conducted tests on five full sections and also collected strength data on …

The Z Files: Reflection On The Practical Implications Of Views About Personal Identity, Marvin Belzer

ICS Fellow Lectures

Zoe Alexander, a 27-year old artist, believes she is the subject of a case study in chapter 7 of Going to Pieces without Falling Apart (Broadway, 1998), a book written by Buddhist psychiatrist Mark Epstein. Zoe feels that her friend Epstein fumbled the analysis badly. Sure, like "Joe" (the case study), when "entering a new relationship [s]he already sees the seeds of his [her] discontent'' -- but more generally Epstein gets her totally wrong. Among the first of THE Z-FILES, then, is Zoe's e-mail to Epstein in which she sets him straight about herself. Along the way she takes the …
