Recent damaging tremors in the Balkans have shown insufficient earthquake performance
of reinforced concrete (RC) buildings intended for residential purposes. In Albania,
typified designs developed by the governmental authorities during the socialist era are used
for many of the buildings intended for residential and governmental services including
administrative centers, health clinics, hospitals, and schools as a common practice to save on architectural fees and confirm quality control. Therefore, such template-designed
buildings must be dealt with first.
This thesis assesses the seismic performance of residential buildings with the chosen
template designs in Albania considering the inelastic response of RC sections. Five
residential buildings with template designs were chosen to represent an important
percentage of residential buildings in mid-size cities located in high seismic districts of
Albania. Selection of template designed buildings and material properties were based on
site investigation on residential buildings in several cities of the region. Pushover curves
of studied buildings were constructed by nonlinear static and incremental dynamic
analyses conducted in two orthogonal directions. The nonlinear dynamic characteristics were represented by equivalent single-degree-of-freedom (ESDOF) systems and their
earthquake deformation demands were estimated under selected ground motions
represented by near and far fault recordings. Seismic performance evaluation was carried
out in accordance with modern seismic guidelines following the capacity spectrum
method. Reasons of building damages during the November 26, 2019 earthquakes are
examined using the results of the performance assessment of studied buildings. The effects
of material quality and detailing effect on the earthquake performance of residential RC
buildings were investigated. The detailed examination of capacity curves and
performance evaluation identified deficiencies and possible solutions for template
designs. Earthquake capacity evaluation was deployed in accordance with capacity
spectrum method.
Evaluation of the capacity curves for the investigated typologies points out that concrete
quality and detailing have remarkable effects in both displacement and lateral load bearing
the capacity of buildings.
The unsatisfactory performance of residential buildings makes the development of
effective and affordable retrofitting techniques essential. The rehabilitation techniques
are broken into two different categories: the local methods, which improve the response
of individual structural elements and the global ones, which operate on the whole
structure. Since in Albania poor material and construction quality is common
problem, the most suitable technique is the use of additional shear walls to increase
lateral load capacity and decrease deformation demands. As a result, existing weaknesses in frame elements would be less pronounced and poor construction quality in buildings could be somewhat compensated. Finally, conclusions are provided, and future research needs on the topic are outlined
Use of Incremental Dynamic Analysis for the seismic performance assessment of RC framed structures
Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
We have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
