14th International Benchmark Workshop on Numerical Analysis of Dams
The Janneh dam is a 162-meter high Roller Compacted Concrete arch-gravity dam under construction in the Nahr Ibrahim Valley of Lebanon. The impounded reservoir will supply water, irrigate agricultural areas and generate hydropower . The dam will serve the Northern areas of Greater Beirut Mount Lebanon . The project site is located in high- seismicity region. The Peak Ground Accelerations are 0.37g and 0.51g respectively for OBE and SEE. Under favorable conditions (shape of the valley, strength of the bedrock, availability of construction materials), the construction of an arch-gravity dam is a more and more interesting alternative. The construction stages are simulated in ABAQUS environment in order to perform both linear and non-linear analyses
A compression-shear fracture growing on an arch-gravity dam
In the case of a narrow valley, characterized by a strong rock mass, the excavation can be designed according to the so called convergent way. In this case, the mean value of the compression stresses at the dam-foundation joint increases as the dam moves towards down-stream under the action of the water pressure applied to the up-stream side. During this slip settlement, the stress level in both materials, concrete and rock, remains allowable. It is true that the seismic load is able to increase such a slip displacement, nevertheless, since the structure is designed for horizontal hydrostatic loads, the stress level remains allowable even in such a seismic condition. The above mentioned issue was discussed during the 14th Benchmark Workshop on the Numerical Analysis of Dams organized by the International Commission on Large Dams (Stockholm, 6–9 September 2017). The theme B of the above mentioned Workshop was the static and seismic analysis of the Janneh dam. It is an arc-gravity dam, 157 meters high, now under construction in Lebanon, a high-seismicity region. The ten participants compared their results, obtained independently from each other and through different numerical models. In this paper the contribution of the authors is presented and the mechanical hypotheses at the base of the three-dimensional evolution of the crack path, at the dam-foundation joint, are discussed
Chiara Lubich, Meditazioni: letteratura come relazione
Chiara Lubich (1920–2008), although the author of 32 books published in 26 countries (178 editions, 3.2 million copies), is better known for her social engagement, as reflected in numerous awards. She began to be regarded as a literary author only in the early 2000s, and primarily from a linguistic rather than literary perspective. This article focuses on her book Meditazioni (Meditations), reconstructs its genesis by tracing the writing process from the late 1950s to her death and the 2021 critical edition, and offers a literary analysis. This reveals Lubich as a forerunner of a new conception of literature: literature as relationship – not only between author and reader, but also among subject, inspiration, and the editorial process
Chiara Lubich: A Saint for a New Global Unity
In this article the author offers an introduction to the life, thought, and impact of Chiara Lubich. He begins with a brief biographical overview and draws attention to some important features of her spiritual teaching: Jesus in the midst, Jesus Forsaken, Mary Desolate, the four nights. He draws attention to the Economy of Communion and as an expression of this spirituality in the world of business and economics, and to the figure of Chiara Luce Badano, a young adherent to the Spirituality of Unity who has been recognized as an example of how this spirituality can lead to holiness of life. The author’s judgment is that Chiara Lubich is “a saint of dialogue.
Manifesto per il museo post-etnografico
The author signes a poetic manifesto for the future of ethnographic museums, beyond colonial representational stereotypes and methodologies
Il museo come metodo. E tu, che cosa vedi?
The chapter reflects upon the current achievements, at international scale, in reference to the education of the adolescents in the museum context. Drawing upon the experience of the "Che cosa vedi?" project, developed by the author herself at the Museo del Novecento, Milan, the chapter explores the scientific horizons, the best practices and the educational methodologies more suit for working with teenagers, such as peer education and debating. "Che cosa vedi?" was focused of the work of 4 prominent Italian artists of the XX century (Lucio Fontana, Toti Scialoja, Luciano Fabro and Mario Merz)
From Canvas to Music: Mathematics as a Tool for the Composition of Jackson Time
The creation of ``Jackson time'' is a project which involves a composer, Davide Amodio, and
a mathematician, Chiara de Fabritiis.
Our common aim was to to ``translate'' a painting by Jackson Pollock, Summertime n. 9,
into a piece of music, making use of different mathematical tools to detect the quantities needed for the
composition. We were inspired by the idea that the painting itself contained some kind of inner--music,
due to the fact that Pollock's moves during the dripping on the canvas had a sort of rhythm, indeed they were often
described by witnesses as a dance.
This paper describes the mathematical background, in particular it illustrates both the analysis
of the painting which was carried out by the two of us and the choice of the mathematical techniques applied to
compute the parameters needed for the composition, which is due to the author. The reader will find a more detailed
report on the composition itself in Davide Amodio's contribution
L'edilizia popolare e ordinaria in Francia: un patrimonio da valorizzare. Il Progetto AMuLoP
The author describes the practices, methodologies and outcomes of a museum project located in the Northern area of Paris and aimed at representing the life of the working class in the aftermath of the Second World War up to the present, with a focus on immigration
Chiara Lubich and the Transformation of Relationships: A Response to “Chiara Lubich and Gender Sociology”
Di Nicola’s essay offers an interesting view of Chiara Lubich’s charism of unity from the perspective of one of society’s main problems: the wound in the relationships between men and women. The violation of the human rights of women, women’s lack of access to political and economic power, and gender discrimination are examples of this wound. The author sheds light on the significance of Lubich’s contribution to this central aspect
