A New Kind Of Body Project: Blogging And The American Teen Girl, Sarah E. Beach

Mahurin Honors College Capstone Experience/Thesis Projects

Through a framework of Joan Jacobs Brumberg’s 1997 work, The Body Project, this paper seeks to provide insight into how the American teenage girl’s body project has adapted and changed through the use of online blogging. Brumberg found that over the course of the 20^th century, girls changed their focus from an inner body project to an outer one. The paper uses a sample of 40 blogs, read in the month of April, 2014, and is divided up into four blog types: diary, pro-ana, style, and whole-self. By reading a girl’s online thoughts, readers will gain valuable insights …

A Forgotten Community: Archaeological Documentation Of Old St. Joseph, Gulf County, Florida, Christopher N. Hunt

USF Tampa Graduate Theses and Dissertations

The town of St. Joseph, established in 1835, served as an important deep-water port for receiving and shipping dry goods up the Apalachicola River north along the vast network of navigable inland waterways in southeastern U.S. during the early nineteenth century. Unfortunately, this town was hit with a yellow fever epidemic and a series of hurricanes that, combined with the infancy of its cotton trade activities, eventually devastated its economy and population. The town disappeared by 1842, only much later to be replaced by modern Port St. Joe (est. 1909), located north of the original settlement. However, St. Joseph's influence …

Shape Optimisation Of Cold-Formed Steel Profiles With Manufacturing Constraints - Part I: Algorithm, Bin Wang, Benoit P. Gilbert, Adrien M. Molinier, Hong Guan, Lip H. Teh

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

This paper presents a Genetic Algorithm optimisation method with manufacturing constraints for shape optimisation of cold-formed steel (CFS) profiles. Previous studies on unconstrained shape optimization of CFS crosssections, where the sole aim was to optimise the weight-to-capacity ratio of the profiles, yielded cross-sections that cannot be manufactured. Current coldforming processes, such as roll-forming and brake-pressing, have limited ability to form continuously curved surfaces without discrete bends. This paper defines simple manufacturing rules and introduces them into the evolutionary algorithm. Augmented Lagrangian constraint-handling technique, with equality and inequality constrained violations, is used to avoid ill-conditioned problems. The ability and accuracy of …

Understanding The Global Buckling Behavior Of Thin-Walled Members With Slotted Web, B. Geleji, M. Szedlák, D. Visy, S. Ádány

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

In this paper flexural buckling of thin-walled members with holes are discussed. Members with few but large openings, as well as with slotted webs are studied. Large number of finite element analyses has been performed, by using a carefully constrained shell finite element model in order to exclude the distortion of the cross-section, which makes it possible to analyze flexural buckling separately from other modes. Based on the results general conclusions are drawn regarding the global behavior of members with holes. Moreover, analytical models are developed for column members with slotted webs, with neglecting or with considering the effect of …

Improved Effective Width Method Considering Distortional Buckling For Cold-Formed Thin-Walled Steel Members With Lipped Channel Section, Xingyou Yao, Yuanqi Li

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

The local buckling, distortional buckling, and overall buckling would occur for cold-formed thin-walled steel members with lipped channel section. The effective width method is used to considering the effect of local and distortional buckling on load-carrying capacity of member in Chinese code. Especially, a very conservative stability coefficient of partially stiffened elements used to considering the local buckling and distortional buckling of flange of lipped channel sections. In this paper, the half-wave length, the elastic buckling stress of distortional-buckling of cold-formed thin-walled steel members with lipped channel section and the corresponding stability coefficient of partially stiffened elements were developed based …

Finite Element Analysis Of Cold-Formed Dimpled Steel Columns, V. B. Nguyen, M. A. English, M. A. Castellucci

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

Dimpled steel products are produced from the combination of an innovative dimpling process and a traditional forming process such as cold-roll forming or press-braking. The wider use of cold-formed dimpled steel members has promoted considerable interest in the local instability and strength of these members. Of particular interest is their buckling behaviour and ultimate strength capacity. However, the dimpling process produces cold-formed sections with a complex ‘dimpled’ surface topography and the ‘dimpled’ material is nonuniformly work hardened through the entire thickness. Owing to these complex issues, there are no existing methods to calculate the buckling strength of the dimpled products …

The Effects Of End Conditions On The Load Capacity Of Cold-Formed Steel Column Members Of Lipped Channel Cross-Section With Perforations Subjected To Compression Loading, Martin Macdonald, Muditha P. Kulatunga

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

The effects of end boundary conditions on the compressive load carrying capacity of cold-formed lipped channel sections with perforations are investigated and discussed. Most structural cold-formed steel members are typically manufactured with perforations. These perforations are pre-cut to accommodate electrical, plumbing, and heating services and so on. Due to the size, shape, and position of perforations and end conditions, ultimate strength and elastic stiffness of a structural member can be varied. This paper describes the ultimate strength results obtained from numerical, experimental, and theoretical investigations for two types of end conditions namely, flat-end and fixed-fixed. The numerical results given have …

Compressive Strength Of Cold-Formed Steel C-Shape Columns With Slotted Holes, L. Xu, Y. Shi, S. Yang

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

Presented in this paper is an experimental investigation on the effect of web holes on the strength of cold-formed steel (CFS) C-shape columns. A total of 18 CFS C-shape stub columns were tested without and with web holes. The column length and web height of C-shape section were 490 mm (19 in) and 150 mm (6 in), respectively; and the lengths of the holes investigated were 74 mm (3 in), 114 mm (4.5 in) and 130 mm (5 in) whereas the width of the holes remains as 38 mm (1.5 in). It is noted that for the strength determination of …

Cold-Formed Steel Lipped Channel Columns Undergoing Local-Distortional-Global Interaction: Experimental And Numerical Investigation, Eliane S. Santos, Pedro Borges Dinis, Eduardo M. Batista, Dinar Camotim

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

Experimental and numerical results concerning the post-buckling behavior and strength of fixed-ended cold-formed steel lipped channel columns experiencing interaction involving local, distortional and global buckling (i.e., stemming from the closeness between the critical buckling stresses associated with these three buckling mode types), are reported. After briefly addressing the column specimen geometry selection, the paper presents and discusses the results of an experimental investigation carried out at COPPE, Federal University of Rio de Janeiro (UFRJ, Brazil) and involving 16 columns − its output consists of steel material properties, initial imperfection measurements, equilibrium paths and failure loads/modes. Then, some test results are …

On The Influence Of Local-Distortional Interaction In The Behavior And Design Of Cold-Formed Steel Web-Stiffened Lipped Channel Columns, André D. Martins, Pedro Borges Dinis, Dinar Camotim, Paulo Providência

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

This paper reports the results of a numerical (ABAQUS shell finite element analysis) investigation on the influence of local-distortional (L-D) interaction in the ultimate strength and design of cold-formed steel fixed-ended web-stiffened lipped channel columns -- hereafter termed “WSLC columns”. These results concern columns with various geometries and yield stresses, ensuring a wide variety of combined ratios between (i) the distortional and local critical buckling stresses, and (ii) the yield and the higher of the above buckling stresses. The objectives of this work are two-fold: (i) to acquire in-depth understanding on the mechanics underlying the L-D interaction in the WSLC …

Cold-Formed Steel Channel Sections With Web Stiffeners Subjected To Local And Distortional Buckling — Part I: Tests And Finite Element Analysis, Liping Wang, Ben Young

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

An experimental investigation of simply supported beams with two different stiffened channel sections has been conducted under both four-point bending and three-point bending about the major axis of the sections. Stiffeners were employed to the web of plain channel and lipped channel sections to improve the flexural strength of cold-formed steel sections that are prone to local buckling and distortional buckling. In this study, the channel sections were brake-pressed from high strength zinc-coated grades G500 and G550 structural steel sheets with nominal 0.2% proof stresses of 500 and 550 MPa, respectively. The high strength stiffened channel sections had the thicknesses …

Health Information Exchange: Growth And Patient Privacy, Niam Yaraghi

Brookings Scholar Lecture Series

Health Information Exchanges (HIE) provide the electronic movement of health-related information among organizations according to nationally recognized standards. The goal of health information exchange is to facilitate access to and retrieval of clinical data to provide safer, timelier, efficient, effective, equitable, patient-centered care. HIEs are becoming integral parts of the national healthcare reform efforts, chiefly owing to their potential impact on cost reduction and quality enhancement in healthcare services. However, the potential of a HIE platform can only be realized when its multiple constituent users actively participate in using its variety of services. In this research, Yaraghi models HIE systems …

Gbtul 2.0 −A New/Improved Version Of The Gbt-Based Code For The Buckling Analysis Of Cold-Formed Steel Members, Rui Bebiano, Dinar Camotim, Rodrigo Gonçalves

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

This paper presents the very recent 2.0 release of software GBTUL – a computer code developed by the authors and made available as freeware at the website of the Department of Civil Engineering of the Technical University of Lisbon (Bebiano et al. 2013). The program performs linear buckling and vibration analyses of thin-walled bars based on Generalized Beam Theory (GBT), a bar theory that accounts for cross-section deformation. Its domain of application is much wider than that of the previous release (1.0ß): indeed, it is now possible to analyze single or multi-span members (i) with various support conditions, including those …

Shape Optimisation Of Cold-Formed Steel Profiles With Manufacturing Constraints - Part Ii: Applications, Bin Wang, Benoit P. Gilbert, Adrien M. Molinier, Hong Guan, Lip H. Teh

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

This paper uses the Genetic Algorithm (GA)-based optimisation method for cold-formed steel (CFS) profiles with manufacturing constraints, developed in the companion paper, to shape-optimise simply-supported and singly-symmetric open-section columns. Having a uniform wall thickness of 0.047 inch (1.2 mm), the columns are subjected to a compressive axial load of 16,860 lbf (75kN) and optimised for yielding and global buckling. Column lengths ranging from 3.28 ft (1,000 mm) to 9.84 ft (3,000 mm) are investigated. The algorithm is run with and without considering the manufacturing constraints. Differences between the two types of cross-sections, i.e. manufacturable and non-manufacturable, are evaluated. The influence …

Constrained Finite Element Method: Demonstrative Examples On The Global Modes Of Thin-Walled Members, S. Ádány

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

In this paper a novel method is presented for the modal decomposition of thin-walled members. The proposed method follows the logic of the constrained finite strip method (cFSM), however, polynomial longitudinal shape functions are applied together with a longitudinal discretization. Thus, strips are transformed into multiple shell finite elements. The longitudinal shape functions are selected in such a way that modal decomposition similar to cFSM can be realized, therefore, the new method can conveniently be described as constrained finite element method (cFEM), possessing all the modal features of cFSM, but with significantly more flexible applicability. The method is briefly presented …

Experimental Study Of Longitudinally Stiffened Web Channels Subjected Predominantly To Shear, Luciano A. Bruneau, Cao Hung Pham, Gregory J. Hancock

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

The Direct Strength Method (DSM) of design of cold-formed sections has recently been extended in the North American Specification for Cold-Formed Steel Structural Members-NAS S100:2012 to include shear. The two new features of the DSM rules for shear researched are the effect of full-section shear buckling as opposed to web-only shear buckling and Tension Field Action (TFA). The prequalified sections in the rules include sections with flat webs and webs with small intermediate longitudinal stiffeners. In order to extend the range to larger intermediate stiffeners as occurs in practice, a series of fourteen shear tests have been performed at the …

Both analytical and test methods are provided in the standard. In this paper, a brief review of the background information and design provisions is provided.

Risk Factors For Recurrent Major Depressive Disorder In A Nationally Representative Sample, Graig Charles Defeo

USF Tampa Graduate Theses and Dissertations

The public use version of the National Comorbidity Survey - Replication (NCS-R) dataset was used (N = 995) to investigate risk factors for recurrent major depressive disorder (MDD) that are evident before recovery from the first major depressive episode (MDE) by comparing persons diagnosed with MDD who experienced a single MDE to persons with recurrent MDD.

Multiple logistic regression analyses assessed the independent risk of recurrent MDD for each of the following risk factors: an early age of onset (old), absence of a life stress trigger, chronic first episode, childhood parental loss, parental maltreatment, parental depression, comorbid anxiety disorder, and …

Polycyclic Aromatic Hydrocarbon Metabolites As A Biomarker Of Exposure To Oil In Demersal Fishes Following The Deepwater Horizon Blowout, Susan Susan Snyder

USF Tampa Graduate Theses and Dissertations

The Deepwater Horizon blowout occurred on April 20th, 2010, releasing 4.9 million barrels of Louisiana crude oil into the Gulf of Mexico (GoM). Subsequent to the Deepwater Horizon blowout, sediment cores revealed oil on the northern GoM seafloor and abnormal skin lesions were seen in GoM fishes. Exposure to polycyclic aromatic hydrocarbons (PAHs), a component of crude oil, in fish has been associated with many sublethal effects, including cancer and population-level effects. Using a biomarker of exposure to PAHs, this thesis evaluates inter-species, temporal and spatial differences in exposure to hydrocarbon contamination between three species of fish with varying levels …

Development Of A New Beam-Column Design Method For Cold-Formed Steel Lipped Channel Members, Shahabeddin Torabian, Baofeng Zheng, Benjamin W. Schafer

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

The structural strength of cold-formed steel lipped channels under combined axial force and biaxial bending moments has been predicted by geometric and material nonlinear collapse analyses performed in ABAQUS and compared to both current, and a newly proposed, beam-column design method. The ABAQUS analyses utilizes a validated modeling protocol calibrated against previous testing by the authors, and including residual stresses and strains, and geometric imperfections; as well as, appropriate cross-section dimensions, member length, and boundary conditions. A total of 75 different lipped channel cross-sections have been selected and the capacity of the beam-column member has been examined under 127 combinations …

Cold-Formed Lean Duplex Stainless Steel Rectangular Hollow Sections In Combined Compression And Bending, Yuner Huang, Ben Young

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

An experimental investigation of cold-formed lean duplex stainless steel members in combined compression and minor axis bending is performed. The test specimens were cold-rolled from flat strips of lean duplex stainless steel grade EN 1.4162 into two rectangular hollow sections. Different eccentricities were applied to the rectangular hollow sections, so that a beam-column interaction curve for each series of test can be obtained. Initial overall geometric imperfections of the members were measured prior to testing. The ultimate loads and the failure modes of each specimen were obtained. Failure modes include flexural buckling as well as interaction of local and flexural …
