Maximum dynamic stress on bridges traversed by moving loads
No full textMost current research on dynamic effects due to traffic load on simply supported bridges focuses on the mid-span section of the bridge, since this location corresponds to the worst static bending moment. However, the maximum total moment allowing for dynamics, may differ considerably from the maximum moment at mid-span. This paper shows how the maximum can occur in a section relatively far from mid-span with a significant difference in magnitude.Other funderJournal websitewww.bridgesjournal.comEuropean 6th Framework Programme ARCHES (Assessment and Rehabilitation of Central European Highway Structures)Publisher requires the journal URL to appear on the record: www.bridgesjournal.com.

Letter to the editor by Co-Chair of Lavender Bridges
No full textThis January 30, 1986 letter to the editor signed Co-Chair, Lavender Bridges addresses the front-page article in the Western Carolinian from January 23 titled “Addressing gay concerns: Lavender Bridges recognized.” The author was misquoted in the article and wishes to set the record straight. Lavender Bridges, an anonymously founded student organization open to all individuals, aimed to promote awareness of lesbian and gay lifestyle, provide lesbian and gay resources, and increase communication with all students and community members. The first organizational meeting took place October 10, 1985 and was officially recognized by the office of Student Development on December 13, 1985. The last mention of the group appeared in the October 10, 1991 issue of the Western Carolinian.Dear Mr. Editor,
I'd like to calf your attention to
the significance of language and
the importance of the use of
particular words to convey the
intended meanings of one person
(or group) to another. Specifically,
I refer to the article about Lavender
Bridges in your January 23 issue.
The only quotation in the
article was carefully planned and
the words were carefully selected
with the intention to convey clearly
that this orgainzation would NOT
address "specific concerns of
sexual orientation" more than
broader concerns affecting all
individuals in a society regardless
of one's sexuality. I am adamant
that if you are to quote an
individual (and in this particular
case you were able to copy from a
written quote) their specific
selection of words must be
considered and carefully
conveyed. On behalf of Lavender
Bridges, I will reiterate the specific
and correct quote that was

The WESTERN CAROLINIAN is published
weekly by the Publication Board of Western Carolina
University. It is an independent student publication
intended for the article:
"While Lavender Bridges
specifically addresses the
concerns of lesbian and gay
students, attendance is not a
reflection of sexual orientation. The
group wishes to extend an
invitation to any individual who is
interested in learning more about
the issues surrounding a lesbian or
gay lifestyle.
In addition, sexual orientation
is not the only area of one's lifestyle.
We assume labels only to begin
defining and clarifying for
ourselves and others who it is that
we really are. For gay people, this
mea ns eve n creati ng new words or
using old words for newer
concepts. We are no more strictly
sexual beings than bisexuals or
heterosexuals. What we are
though, has been overshadowed
by the labels which have been
used to create frightening myths
about us.
Sincerely,
Co-Chair, Lavender Bridge

Literature review on the images of the nurse and nursing in the media
No full textThis study concentrates on the images of the nurse and nursing seen most commonly in the media and attempts to trace the images back to their origins and to explain their continued use, despite the rapidly changing role of the nurse in today's world. The images have been derived mostly from the historical roots of nursing and sometimes as a reaction to the increasing influence of the feminist movement. The author takes a look at the four main images of the nurse seen in the media, which are the ministering angel, the battleaxe, the naughty nurse and the doctor's handmaiden and then goes on to take a brief look at the other images commonly perpetuated by the media. The author summarizes the probable effects of the media stereotypes on nurses themselves and the service they provide and also takes a look at attempts to dispel these stereotypes
Making change happen
No full textThis book is a unique window into a dynamic time in the politics and history of Australia. The two decades from 1970 to the Bicentennial in 1988 saw the emergence of a new landscape in Australian Indigenous politics. There were struggles, triumphs and defeats around land rights, community control of organisations, national coalitions and the international movement for Indigenous rights. The changes of these years generated new roles for Aboriginal people. Leaders had to grapple with demands to be administrators and managers as well as spokespeople and lobbyists. The challenges were personal as well as organisational, with a central one being how to retain personal integrity in the highly politicised atmosphere of the ‘Aboriginal Industry’. Kevin Cook was in the middle of many of these changes – as a unionist, educator, land rights campaigner, cultural activist and advocate for liberation movements in Southern Africa, the Pacific and around the world. But ‘Cookie’ has not wanted to tell the story of his own life in these pages. Instead, with Heather Goodall, a long time friend, he has gathered together many of the activists with whom he worked to tell their stories of this important time. Readers are invited into the frank and vivid conversations Cookie had with forty-five black and white activists about what they wanted to achieve, the plans they made, and the risks they took to make change happen
Methodology for Diagnostic Load Testing
No full textThis chapter deals with the methodology for diagnostic load testing. All aspects of diagnostic load testing that are shared with other load testing methods have been discussed in Part II. In this chapter, the particularities of diagnostic load testing of new and existing bridges are discussed. These elements include loading procedures, monitoring behavior during the test, reviewing test data, calibrating analytical models, and evaluating the test results.Accepted Author ManuscriptConcrete Structure
Durability of pretensioned concrete girders in coastal climate bridges: Basis for better maintenance and future design
No full textThis study was based on findings from the Norwegian Public Roads Administration's Bridge Management System and field investigations on corrosion damage in pretensioned Norwegian standard I-beam (NIB) girders in 227 coastal climate bridges. The main durability design parameters are summarized and related to regulations over the last 80 years. Environmental exposure is discussed in the light of the global, local, and micro climate. We found that 51% of the bridges have girder corrosion damage. The percentage is highest for bridges built when the cover thickness required was lowest. Cover thickness below that required (resulting from production faults) caused 74% of corrosion damage. Most of the severe chloride-induced corrosion damage in bridges was found in the inner NIB girders, particularly in the support-zones and their vicinity. This can be due to interaction between geometry and exposure. Corrosion of reinforcement in support-zones can impact structural behavior, particularly NIB girder shear performance.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Applied Mechanic
Shear Force in Bolted Connection Due to Traffic and Temperature Loads in Hybrid Steel-FRP Bridges
No full textAs many bridges are reaching the end of their service life, researchers are searching for new solutions to extend the lifespan of those bridges. Fibre reinforce polymers (FRP) could be possible a solution for bridges with deck problems. Lightweight FRP decks can be installed quickly via bolted connectors on steel substructure. In general, shear force in the connector is not taken into account during the design of FRP decks because slip behaviour and interaction with steel substructure is unknown. This research connects to research at TU Delft on non-slip shear connectors for FRP decks. Aim of this paper is to quantify shear forces in bolted connectors due to traffic and temperature loads. The direction of webs, fibres in panel facings and the expansion coefficient of resin has been investigated to determine the influence of the FRP deck on the shear force in the connectors. To investigate the results of traffic loading and temperature loading on real bridges, a database of bridges in the Netherlands has been used. Results from the analyses offer an indication of the influence of the laminates on the shear force in the connectors and show shear force ranges that can occur in existing bridges.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Steel & Composite Structure
Assessment of existing concrete bridges by load testing
No full textOne of the methods for the assessment of existing bridges is to subject the bridge to a load test. What is still lacking is a reflection of these recent advances in the codes and guidelines used for load testing of bridges. Two approaches are being used to address this lack. The first approach attempts to answer fundamental questions with regard to bridge load testing, and in particular proof load testing of concrete bridges through research. The second approach is to coordinate efforts, and facilitate collaboration and exchange of ideas internationally through the creation of the IABMAS Technical Committee on Bridge Load Testing. It is expected that these efforts will lie at the basis of improved recommendations for the assessment of concrete bridges by load testing to be included in codes and guidelines and to serve the community of engineers faced with the increased task of assessing ageing infrastructure.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Concrete Structure
Building Brownian Bridges to Learn Dynamic Author Representations from Texts
No full textInternational audienceAuthors writing habits fluctuate throughout their lives. This evolution may stem from engaging in new topics, new genres or by the variation of their writing style. However, most representation models aiming at building meaningful authors embedding focus on static repre- sentations. They skip the precious time information useful to build more powerful and versatile representations. Only a limited number of meth- ods learn dynamic representations, each dedicated to a time bin. Here we propose a new representation learning model called BARL (Brown- ian Bridges for Author Representation Learning). BARL uses Brownian Bridges, a Gaussian process, to embed authors as continuous trajectories through time. Leveraging the Variational Information Bottleneck (VIB) framework, it integrates a pre-trained temporal text encoder to encode authors and documents into the same space, learning a distinct dynamic for each author along with a customized variance. We evaluate BARL on several tasks: authorship attribution, document dating and author classification on two datasets from the literature. BARL outperforms baselines and existing dynamic author embedding models while learning a continuous temporal representation space
