The Physiological Effects Of Precooling Beverage Temperatures On Heat Strain In Collegiate Women Soccer Players, Taylor Welch

USF Tampa Graduate Theses and Dissertations

Precooling is a method used to decrease initial pre-exercise core temperature in order to facilitate a greater margin for heat production before a maximum core temperature is reached. The purpose of this study was to examine the differences in physiological and perceptual effects of precooling using beverages of three different temperatures: room temperature beverage (24.88 ± 1.13°C), cold beverage (6.15 ± 3.16°C) and ice slushy (-1.61 ± 0.45°C) in a hot environment (27.88 ± 0.72°C and 35.36 ± 0.83°C for wet globe bulb temperature and dry bulb temperature respectively). For all trials the environmental temperature was set to 35°C with …

Improvements To The Prediction Of Brace Forces In Z-Purlin Roof Systems With Support + Third Point Bracing, Michael W. Seek

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

The Component Stiffness Method is a displacement compatibility method used to analyze C- and Z- section supported roof systems. The method provides a detailed analysis of the flexibility in the roof system and the distribution of forces as they flow out of the system. Parametric studies of the equations for typical roof systems have shown that by ignoring the flexibility of some of the components, the method can be simplified with little impact on the anchorage forces calculated. Changes have also been made to the way in which cross section deformations are incorporated into the method. This paper focuses on …

Numerical Investigation Of Cold-Formed Steel Top Hat Purlins, Asraf Uzzaman, Andrzej M. Wrzesien, Robert Hamilton, James B. P. Lim, David Nash

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

This paper considers the use of cold-formed steel top-hat sections for purlins as an alternative to conventional zed-sections. The use of such top-hat sections may be viable for use in cold-formed steel portal framing systems, where both the frame spacing and purlin span may be smaller than in conventional hot-rolled steel portal frames. Furthermore, such sections are torsionally stiffer than zed-sections, and so have a greater resistance to lateral-torsional buckling. They also do not require the installation of anti-sag rods. The paper describes non-linear elasto plastic finite element analyses conducted on top-hat sections. The results of twenty-seven tests on four …

Influence Of Diagonal Bracing Restraint On Cold-Formed Steel Perforated Columns Under Axial Compression, Chong Ren, Xianzhong Zhao

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

This paper presents a numerical investigation on the influence of diagonal bracing restraint on cold-formed steel perforated columns subjected to axial compression. Finite element method (FEM) is employed to analyse the structural behaviour of perforated columns. The results obtained from the present study highlight the influence of diagonal bracing restraint on post-buckling of columns, and the distortional-flexural mode interaction is also discussed. Furthermore, the accuracy of the present model is validated by comparing the results against the available experimental data.

Development Of A Novel Pinned Connection For Cold-Formed Steel Trusses, Chris D. Mathieson, G. Charles Clifton, James B. P. Lim

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

Cold-formed steel trusses are a popular form of construction for light-weight buildings, particularly portal frame structures, for which spans up to 25m are increasingly common. In these long span trusses, providing high strength connections with sufficient elastic stiffness is a current limitation to developing cost-effective solutions. A novel pin-jointed truss connection named the Howick Rivet Connector (HRC) has been tested, firstly in a T-joint arrangement, then in a truss assemblage to determine its reliable strength and stiffness. Results showed that the HRC performs similarly to a bolted connection in terms of failure modes observed and loads reached. Additionally, the process …

Towards Load-Deformation Models For Screw-Fastened Cold-Formed Steel-To-Steel Shear Connections, C. D. Moen, D. A. Padilla-Llano, S. Corner, C. Ding

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

This paper summarizes results from an experimental program considering single-fastened cold-formed steel-to-steel shear connections. Fastener motion (displacement and tilting angle) and bearing deformation occurring on the connecting members at the fastener location were captured using an automated, optical non-contact measurement procedure. The results are used to relate cold-formed steel-to-steel shear connection load-deformation response to tilting and bearing response. A general steel-to-steel single shear fastener load-deformation equation is also proposed and demonstrated.

Fragility Curves For Thin-Walled Cold-Formed Steel Wall Frames Affected By Ground Settlements Due To Land Subsidence, Luis A. Hernández-Castillo, Jose A. Ortiz-Lozano, Martin Hernández-Marín, Jesús Pacheco-Martínez, Mario E. Zermeño-Deleón, Juan J. Soto-Bernal, Jorge Ramos-Ruizflores, Miguel A. Soto-Zamora

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

Land subsidence phenomenon due to ground water withdrawal is a current problem in many places around the world, particularly in the shallows of Mexico. This causes ground differential settlements that affect structures, mainly dwellings and buildings based on reinforced concrete and masonry. Eventually, these structural materials do not exhibit an adequate performance beyond a certain level of angular distortion. This work presents the results about a study regarding the performance of thin-walled cold-formed steel wall frames with different sheathing systems affected by angular distortions simulating ground differential settlements due to land subsidence. The wall frames are composed by vertical (studs) …

Fastener-Based Computational Models With Application To Cold-Formed Steel Shear Walls, G. Bian, S. G. Buonopane, Hung Huy Ngo, Benjamin W. Schafer

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

The objective of this paper is to validate a tool that design engineers could employ to develop mechanics-based predictions of the lateral response of wood-sheathed cold-formed steel (CFS) framed shear walls applicable in a wide variety of situations. Wood framed shear walls enjoy a variety of tools, most notably SAPWood and its predecessor CASHEW, that provide a means to predict the complete hysteretic behavior of a shear wall based on the nail fastener schedule and board selection. The existence of these tools helps engineers in unique design situations, encourages innovation in shear wall design particularly for Type I shear walls, …

Study On The Flexural Capacity Of Cold-Formed Steel Joists-Osb Composite Floors, X. H. Zhou, Y. Shi, R. C. Wang, Y. J. Liu

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

Two full scale specimens were tested to study the flexural capacity of cold-formed steel joists and OSB (Oriented strand board) composite floors. Test results indicated the composite floors had high bearing capacity and small deformation, and the screw spacing significantly affected the load-carrying capacity. The main failure modes were flexural and torsional buckling of floor joist, and the interactive buckling of compression flange, web and crimp. The wave length of bucking equalled to the adjacent screw spacing. Then the specimens were analyzed by commercial software ANSYS and the nonlinear FEM calculation results agreed well with the test results. Furthermore, detailed …

Acoustic Performance Of Different Cold-Formed Studs In Double-Leaf Walls By Finite Element Analysis And Experiment, V. B. Nguyen, T. Morgan, M. A. English, M. A. Castellucci

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

Cold-formed steel studs are often used in lightweight partition walls to provide structural stability but in the same time they change the acoustic performance of the whole system. The overall design of such lightweight structures for acoustic sound insulation becomes very complicated as the sound passing through stud needs to be quantified. One of the greatest challenges is to characterise the stud’s geometric effects on the sound transmission of the partition walls. This paper presents a Finite Element modelling approach and results into the acoustic performance of cold-formed studs in double-leaf walls which are placed in between a source room …

In-Plane Behavior Of Cold-Formed Steel-Framed Shear Wall Panels Sheathed With Fibre Cement Board, Rojit Shahi, Nelson Lam, Emad Gad, Ismail Saifullah, John Wilson, Ken Watson

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

Shear wall panels are commonly used as lateral load resisting elements to provide stability of the cold-formed steel-framed houses in Australia against wind and earthquake actions. The effectiveness of their lateral resistance behavior is obtained usually by experimental testing although it can also be done by analytical modeling. This paper presents racking test results of steelframed wall panels with different aspect ratios sheathed with fibre cement board subjected to monotonic and cyclic loading protocol. Performance parameters of the wall panels are obtained from the experimentally observed load-deflection curves using various existing methods and evaluation method is proposed. The evaluation method …

Experimental Seismic Behavior Of The Cfs-Nees Building: System-Level Performance Of A Full-Scale Two-Story Light Steel Framed Building, Kara D. Peterman, Rob L. Madsen, Benjamin W. Schafer

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

In the summer of 2013, testing of two full-scale cold-formed steel (CFS) framed buildings under seismic excitations took place at the Structural Engineering and Earthquake Simulation Lab (SEESL) at the University at Buffalo. Utilizing the twin shake tables, the two-story building specimens were subjected to ground motions from the 1994 Northridge earthquake. These experiments were conducted as a part of the CFS-NEES experimental effort in an attempt to advance cold-formed steel earthquake engineering and design. Two buildings were tested: the first, a specimen constructed with only structural components (CFS-framed gravity walls, shear walls, floor and roof diaphragms, with OSB sheathing …

Pull-Through Failure Tests Of Thin Steel Roof Battens Under Wind Uplift Loads, Mayooran Sivapathasundara, Mahen Mahendran

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

Thin profiled steel roof sheeting and battens are increasingly used in the construction of roofing systems of residential, commercial, industrial and farm buildings in Australia. The critical load combination of external wind suction and internal wind pressures that occur during high wind events such as thunderstorms and tropical cyclones often dislocate the roofing systems partially or even completely due to premature roof connection failures. Past wind damage investigations have shown that roof sheeting failures occurred at their screw connections to battens. In most of these cases, the screw fastener head pulled through the thin roof sheeting whilst the screw fasteners …

Local Buckling Hysteretic Nonlinear Models For Cold-Formed Steel Axial Members, D. A. Padilla-Llano, C. D. Moen, M. R. Eatherton

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

This paper studies the energy dissipation and damage in thin walled members that experience local buckling and presents an approach to model cold-formed steel (CFS) axial members that experience local buckling deformations. The model is implemented in OpenSees using hysteretic models for CFS axial members calibrated using experimental responses. Results from thin-shell element simulations using ABAQUS show that energy dissipation in thin plates dissipates through inelastic strains and yielding that concentrates in damaged zones that extent approximately the length of a buckled half-wave (L_cr). Generally damage accumulates in one zone but when more than one damaged zone occurred …

Latino Men Managing Hiv: An Appraisal Analysis Of Intersubjective Relations In The Discourse Of Five Research Interviews, Will Caston

Dissertations and Theses

Latino men, particularly those who have sex with other men, have been disproportionately affected by HIV/AIDS. Scholars have sought for nearly two decades to understand how various social and cultural factors in the Latino community exacerbate HIV risk among these men. Although following the advent of life-sustaining medications in 1996, HIV is often regarded as a manageable chronic illness, as opposed to a death sentence, scant attention has been devoted to how HIV-positive Latino men experience managing the illness. Among studies that have focused on HIV-positive persons' illness management, few Latino men have participated.

Using the Appraisal framework from Hallidayan …

Patch Or Rebuild: A Comparative Analysis Of Multi-Agency Regime Vs. Single-Agency Regime Within Us Domestic Space Traffic Management Regulation, Susan L. Willshire

Space Traffic Management Conference

It has been suggested that expansion and modification of the current US regulatory regime is sufficient to regulate space traffic. It has also been suggested that a consolidation of the existing fragmented structure into a single agency would be superior. This article provides a detailed pro vs. con comparative analysis of the two approaches as they relate to civil space traffic and commerce. Expanding commercial needs place specific demands on the regulatory next steps and require thoughtful prioritization and coordination of efforts to ensure a successful future regulatory regime that addresses the competing needs of agencies and industry. The proper …

Integration Of Aerospace Operations Into The Global Air Traffic Management System, Martin Griffin

Space Traffic Management Conference

Commercial aerospace operations are a reality. Companies are already carrying out flight trials and will be carrying the first passengers and freight in the near future. The commercial development of more vehicles is underway. This situation can be equated to a similar stage in the development of Remotely Piloted Air Systems (RPAS) where technological advances took place at a far faster pace than envisaged leading to a fragmented regulatory and operational situation which is still not resolved at the present time.

In the initial phases of development of space operations, activities were carried out as a function of the State …
