Feasibility Study For A Repetitive Member Factor For Cold-Formed Steel Framing Systems, S. Clayton, S. F. Stephens Nov 2010

Feasibility Study For A Repetitive Member Factor For Cold-Formed Steel Framing Systems, S. Clayton, S. F. Stephens

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

Cold-formed steel has become a preferred building material for structural framing in many different types of structures, commonly used as repetitive members such as floor joists, roof rafters, roof trusses and wall studs. For wood framed structures with repetitive members, a repetitive member factor increases the allowable bending stress from 1.00 to 1.50 times the reference design value, depending on both the type of material and the type of load. Currently, however, the bending strength of cold-formed steel repetitive members is not permitted to be increased, even though the method of framing is quite similar to that of wood except …


Improvements To The Fire Performance Of Light Gauge Steel Floor Systems, B. Baleshan, M. Mahendran Nov 2010

Improvements To The Fire Performance Of Light Gauge Steel Floor Systems, B. Baleshan, M. Mahendran

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

Light gauge steel frame (LSF) struct ures are increasingly used in commercial and residential build ings because of their non- combustibility, dimensional stability and ease of installation. A common application is in floor-ceiling systems. The LSF floor-ceiling systems must be designed to serv e as fire compartment boundaries and provide adequate fire resistance. Fire-rated floor-ceiling assemblies have been increasingly used in buildings. However, limited research has been undertaken in the past and hence a thorough understanding of their fire resistance behaviour is not available. Recently a new composite floor-ceilin g system has been developed to provide higher fire rating. But …

Evaluation Of The Flexural Strength Of Cold-Formed Steel Studs With Embossed Flanges, K. B. Reynolds, S. F. Stephens, Roger A. Laboube

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

New advances and improvements in the manufacture of cold-formed steel shapes are continually being made. One such advancement in the manufacturing of steel studs is flange embossing, a technique used to facilitate the installation of drywall screws into the stud flange. Currently, embossed flanges are not specifically addressed in the North American Specification for the Design of Cold-Formed Steel Structural Members (AISI S100), thereby drawing into question the use of current design equations from being used to calculate member properties for an embossed stud. A limited experimental investigation was undertaken to determine if light flange embossing affects the nominal flexural …

Chronic Spontaneous Activity Generated In The Somata Of Primary Nociceptors Is Associated With Pain-Related Behavior After Spinal Cord Injury, Supinder S Bedi, Qing Yang, Robyn J Crook, Junhui Du, Zizhen Wu, Harvey M Fishman, Raymond J Grill, Susan M Carlton, Edgar T Walters Nov 2010

Chronic Spontaneous Activity Generated In The Somata Of Primary Nociceptors Is Associated With Pain-Related Behavior After Spinal Cord Injury, Supinder S Bedi, Qing Yang, Robyn J Crook, Junhui Du, Zizhen Wu, Harvey M Fishman, Raymond J Grill, Susan M Carlton, Edgar T Walters

Faculty, Staff and Student Publications

Mechanisms underlying chronic pain that develops after spinal cord injury (SCI) are incompletely understood. Most research on SCI pain mechanisms has focused on neuronal alterations within pain pathways at spinal and supraspinal levels associated with inflammation and glial activation. These events might also impact central processes of primary sensory neurons, triggering in nociceptors a hyperexcitable state and spontaneous activity (SA) that drive behavioral hypersensitivity and pain. SCI can sensitize peripheral fibers of nociceptors and promote peripheral SA, but whether these effects are driven by extrinsic alterations in surrounding tissue or are intrinsic to the nociceptor, and whether similar SA occurs …

Mimo Channel Spatial Covariance Estimation: Analysis Using A Closed-Form Model, Yanling Yang Nov 2010

Mimo Channel Spatial Covariance Estimation: Analysis Using A Closed-Form Model, Yanling Yang

Theses and Dissertations

Multiple-input Multiple-output (MIMO) wireless communication systems allow increased spectral efficiency and therefore promise significant improvement in performance. However, because of the rapid variation in channel state information (CSI) in networks with mobile nodes or scatterers, it is difficult both to maintain high communication performance and to create channel models that effectively represent the time-varying behavior of the channels. The spatial covariance of the MIMO channel describes the average power gain on each transmit-receive antenna pair as well as the correlation between the complex link gains and thus provides critical information for understanding the performance of the system and for creating …

Cfsei Educating North American Practitioners In Principles Of Cfs Framing Design, W. D. Allen Nov 2010

Cfsei Educating North American Practitioners In Principles Of Cfs Framing Design, W. D. Allen

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

Educating North American structural engi neers in the principles of cold-formed steel (CFS) design in general, and about CFS framing in particular, has a unique set of challenges. The undergraduate curri cula virtually ignore the subjects, and only a handful of graduate programs address the issue. Several industry associations have existed for engineers, but none specialize in CFS framing. Several organizations existed in the co ld-formed steel framing marketplace, but none were set up to accommodate engi neers. This paper will review the formation, development, growth, and maturation of one such education- and engineer-focused organization within the framework of the …


Screw Connections Subject To Tension Pull-Out And Shear Forces, R. M. Francka, R. A. Laboube Nov 2010

Screw Connections Subject To Tension Pull-Out And Shear Forces, R. M. Francka, R. A. Laboube

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

Currently, the behavior of screw connections subject to combined tension pull- out and shear forces is not well understood. An experimental study was conducted at Missouri Un iversity of Science and Technology to better understand the relationship or interac tion between these forces. The test program evaluated four parameters that may influence the behavior of pure tension and pure shear in screw connections: the thickness of the sheet not in contact with the screw head, the ultimate strength of the steel, the ductility of the steel, and the screw diameter. Based on the behavior observed and analysis of the test …


Shear Behavior Of Screw Connections For Cold-Formed Thin-Walled Steel Structures, Yuangqi Li, Xingyou Yao Nov 2010

Shear Behavior Of Screw Connections For Cold-Formed Thin-Walled Steel Structures, Yuangqi Li, Xingyou Yao

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

Self-drilling screws are the primary mean s to fasten cold-formed thin-walled steel members in construction. There are several failure modes for shear connections with self-drilling screws, including screw tilting, hole bearing, edge tearing, tensile fracture in net s ection of connected elements and shear fracture of screws. Meanwhile, the “g roup effect” will exist when a large number of screws are used in a shear connection. A series of tests (75 specimens) on single lap shear connections with self-drilling screws has been carried out and the results report ed in this paper. The end distance, screw spacing, pattern of screws …

Mirabai Comes To America: The Translation And Transformation Of A Saint, Nancy M. Martin Nov 2010

Mirabai Comes To America: The Translation And Transformation Of A Saint, Nancy M. Martin

Religious Studies Faculty Articles and Research

The story of the sixteenth-century Hindu saint Mirabai is told and performed in a multitude of genres in India across the centuries, and her songs generate a tradition of continuing composition in her name. Her popularity readily moves across boundaries of language, caste, class, religion, and culture not only within India but also beyond, taking root in American culture more broadly in the latter decades of the 20th century, as Americans begin looking for figures for inspiration and canonisation within an emerging non-institutionalised global spirituality and women around the world mine the past to find their spiritual foremothers. Her popularity …

Evaluation Of Metabolic Stress Between Jumping At Different Cadences On The Digi-Jump Machine, Thomas S. Lyons, James W. Navalta, Zachary J. Callahan

International Journal of Exercise Science

The American College of Sports Medicine (ACSM) recommends that healthy adults achieve a minimum of thirty minutes of moderate intensity aerobic exercise five days per week. While cycling, walking, and jogging are commonly observed methods of achieving these recommendations, another option may be repetitive jumping. The purpose of this study was to examine the metabolic responses between repetitive jumping at a cadence of 120 jumps per minute (JPMs) vs. 100 JPMs when utilizing the Digi-Jump machine. Twenty-eight subjects completed two jumping trials, one at 120 JPMs and one at 100 JPMs. Subjects jumped until volitional exhaustion, or for a maximum …
