An Exafs Study Of Nanocrystalline Yttrium Stabilized Cubic Zirconia Films And Pure Zirconia Powders, Georgina E. Rush, Alan V. Chadwick, Igor Kosacki, Harlan U. Anderson

Materials Science and Engineering Faculty Research & Creative Works

Detailed EXAFS (extended X-ray absorption fine structure spectroscopy) measurements have been collected for two nanocrystalline forms of zirconia, namely, dense films of yttria-stabilized cubic zirconia (YSZ) and tetragonal phase powders of pure ZrO2. Zr and Y K edge EXAFS spectra for the YSZ films with grain sizes of 6, 15, and 240 nm showed no major differences with the corresponding spectra of the bulk counterpart. This is clear proof that these nanocrystalline films exhibit similar levels of disorder to that of large crystals. In particular, there is no support for the view that the intergrain regions are highly disordered, and …

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 …

Buckling Of Cold Formed Stainless Steel Columns Under Concentric And Eccentric Loading, J. Rhodes, M. Macdonald, W. Mcniff

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

This paper describes the results obtained from a series of compression tests performed on cold formed stainless steel Type 304 columns of lipped channel cross-section. The cross-section dimensions, the column length and the eccentricity of the applied compressive load are varied to examine the effects on the buckling load capacity of the columns. The results obtained are compared to those obtained from the relevant design specifications in America and in Europe, and conclusions are drawn on the basis of the comparisons.

Distortional Buckling Of Cold-Formed Stainless Steel Compression Members, A. Liang, G. J. Van Den Berg, Rudolph Laubscher

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

In this paper the critical local buckling strength of cold-formed stainless steel compression members, with special emphasis on the method developed by Lau and Hancock for distortional buckling is discussed. Cold-formed stainless steel channel and I-section members under axial compression in distortional buckling are analysed. A control experiment is carried out for comparing analytical methods with a finite element method and experimental values.

Mechanical Properties Of Stainless Steel Lipped Channels, M. Macdonald, J. Rhodes, G. T. Taylor

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

This paper describes and discusses the results obtained from a series of tensile tests performed on cold formed stainless steel Type 304 members of lipped channel cross-section. Standard tensile tests on coupons cut from the webs of the sections were carried out, as were full section tensile tests. Ramberg-Osgood type curves based on the procedure suggested in the ASCE design code were fitted to the stress-strain results and these are compared with the experimental results and Ramberg-Osgood type curves derived on an alternative basis.

Fe Models For Sheeting Under Interaction Load, Jan Kerstens, Bert Snijder, Monique Bakker, H. Hofmeyer

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

Experiments show that, after ultimate load, sheeting may fail by three distinct post-failure modes. In this paper, three finite element models are presented, one for each post-failure mode. One of the finite element models was difficult to develop. A spring model explains this. The finite element models show that, at ultimate load, only two different ultimate failure modes exist. This is important for the development of mechanical models for sheeting failure.

Lateral Buckling Of Prismatic Members About An Imposed Axis Of Rotation, Leopold K. Sokol

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

This paper deals with the lateral buckling of prismatic members whose position of the axis of rotation is imposed by the conditions of lateral support. As a function of the type of connection with the lateral support, the rotation may be free or hindered (elastic end restraint). This may concern, for instance, the case of a purlin stabilized by a roof structure or of a column stabilized by an external cladding or by another type of efficient continuous bracing. Usually, the check of this type of instability is complex and leads to sophisticated and tedious computations. In order to avoid …

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 …

Spatial Buckling Behavior Of High-Rise Rack Frames, Lip H. Teh, Gregory J. Hancock, Murray J. Clarke

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

The paper investigates the global elastic buckling behavior of a high-rise adjustable pallet rack frame composed of thin-walled open sections. It is concluded that the simple element used in many commercial programs for 3D frame analysis is not sufficiently refined for accurate linear buckling analyses of high-rise rack frames.

Structural Stability Of Braced Scaffolding And Formwork With Spigot Joints, John Enright, Robert Harriss, Gregory J. Hancock

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

Steel Scaffolding systems are often constructed from cold-formed circular hollow sections. The beams of this system are normally called "ledgers" and the columns are normally called "standards". To allow the system to be quickly erected on site, "spigot joints" are inserted in the standards. The spigot joints consist of smaller diameter tubes which slide into the larger diameter tubes to provide a safe connection under gravity load. However, the spigot joints may have a lack of fit, and when located midway between the ledgers, they can cause significant out-of-straightness in a standard. This PΔ effect may weaken the standard as …

Dynamic Behaviour Of Floors With Cold-Formed Steel Joists, L. Xu, Z. Ling, W. C. Xie, R. M. Schuster

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

Presented in this paper are the results of a recent study carried out at the University of Waterloo on the performance of residential floors supported by cold-formed steel C-section floor joists. Both static and dynamic tests were conducted on steel floors with different span lengths based on different design criteria. The purpose of the static tests was to evaluate the stiffuess and load sharing among the joists, and the purpose of the dynamic tests was to evaluate the dynamic characteristics such as frequencies of the floor systems. To identify the critical parameters that contribute to the control of floor vibration, …

L-Header Testing, Evaluation And Design Methodology, Roger A. Laboube, N. R. Elhajj

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

Cold-formed steel L-shaped headers have gained popularity over the past few years due to their simplicity and cost effectiveness. While cold-formed steel conventional headers are widely used and can be designed for most applications, often it is necessary to reduce cost by using less material and labor hours. The L-shaped header provides both, a fast and economical solution to safely transfer applied loads to other structural elements in a building. As the name suggests, the main components of an L-shaped header is a piece of cold-formed steel formed into a shape resembling the letter L. An L-header assembly consists 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 …
