Advanced numerical modeling of masonry vaulted structures based on BIM parametric geometry generation

Vaults are an architectural element which during construction history have been built with a great variety of different materials, shapes, and sizes. The shape of these structural elements was often dependent by the necessity to cover complex spaces, by the needed loading capacity, or by architectural aesthetics. Within this complex scenario masonry patterns generates also different effects on loading capacity, load percolation and stiffness of the structure. These effects were been extensively investigated, both with empirical observations and with modern numerical methods. While most of them focus on analyzing the load bearing capacity or the texture effect on vaulted structures, the aim of this analysis is to investigate on the effects of the variation of a single structural characteristic on the load percolation in the vault. Moreover, an additional purpose of the work is related to the coding of a parametrical model aiming at generating different masonry vaulted structures. Nevertheless, proposed script can generate different typology of vaulted structure basing on some structural characteristics, such as the span and the length to cover and the dimensions of the blocks.

Accudire l’umanità. Proposta di traduzione, analisi e commento del racconto breve di fantascienza cinese Shanyang Renlei di Liu Cixin.

The main topic of this thesis is the italian translation from Chinese of the 2005 short science fiction story, Shanyang Renlei 赡养人类 (known as For the Benefit of Mankind/The Wages of Humanity in English), by Liu Cixin 刘慈欣, the leading figure in contemporary Chinese science fiction, and the analysis of the major problems and challenges encountered during the translation. In terms of its internal structure, the thesis is divided into four chapters. The first chapter is an introduction both for science fiction enthusiasts and laypersons. Thus, it starts with the very concept of “science fiction”; then it analyzes some of the most relevant definitions of the genre throughout the years, with particular attention to the one proposed by Darko Suvin; lastly, it presents a brief but thorough excursus that goes all the way through the origins and development of science fiction in the West and of kehuan xiaoshuo in China, so that the readers can have a glimpse into their similarities and differ-ences as they evolved. The second chapter focuses on Liu Cixin himself and his works. After a short account of the novels and short stories that are considered the most representative of the three creative phases of his career as a science fiction author, with a section dedicated to his opus magnum, the trilogy Diqiu Wangshi 地球往事 (Remembrance of Earth’s Past), the chapter then goes on to analyze the most characteristic features and themes of his narrative style. The chapter ends with a detailed description of the plot of Shanyang Renlei and an in-depth look at the thematic content of the story. Chapters Three and Four presents, respectively, the Italian translation of the short story, and the thorough analysis of some of the most interesting and challenging issues that have arisen during the translation, along with an illustration of the corresponding strategies and solutions.
