RESUMENEl edificio en estudio es emblemático. Se encuentra desplantado sobre un suelo arcilloso. Ha sufrido modificaciones por motivos estructurales, arquitectónicos, estéticos y funcionales. La construcción de este templo data del siglo XVI. Se construyó con mampostería de piedra natural junteada con arcilla y techumbre de madera. Su planta está conformada por una sola nave rectangular de 12 m de ancho x 50 m de largo, la cual contempla 5 contrafuertes laterales, que presentan falla estructural en sus extremos superiores e inferioresAl analizar las causas del origen de las fracturas presentes, se comprueba que el edificio se construyó de acuerdo a la geometría propuesta en diversos tratados antiguos, lo que supondría un adecuado comportamiento mecánico. Se presentan las principales conclusiones obtenidas del análisis estructural realizado a los botareles de los contrafuertes, así como del estudio de Mecánica de Suelos realizado, concluyéndose que las fracturas presentes en los botareles de los contrafuertes se deben a la inadecuada selección de la mampostería natural empleada y a un inadecuado procedimiento constructivo.Palabras clave: Fábrica; tratados; edificios históricos; contrafuertes; botareles.ABSTRACTThe Tiripetío building is emblematic. It is founded on a clay soil. It has undergone modifications due to structural, architectural, aesthetic and functional reasons. The construction of this temple dates back from the 16th century. It was built with stone masonry natural binder with clay and wood roof. The plant consists of a single rectangular bay of 12 m wide x 50 m in length, which includes 5 lateral buttresses, showing structural failure in the upper and lower ends. To analyze the root causes of the fractures, it was checked that the building was built according to the geometry described in various former treaties which would have a proper mechanical behavior. The main conclusions obtained from the structural analysis at botareles buttresses, as well as the study of soil mechanics, were that fractures present at the botareles of the buttresses are due to improper selection of the used natural masonry as well as an inappropriate construction procedure.Keywords: Factory; treaties; historic buildings; buttresses; flying buttresses.

Repairs of historic buildings require the selection of such the design solutions to achieve the intended effects while ensuring the effectiveness of these repairs. This is particularly important in case of the structural failures of these facilities. Most of the conservation recommendations for renovations of cultural heritage buildings and monuments in Poland concern the preservation of the original building material, construction as well as the shape and appearance of the repaired facility [1]. The basic tasks for the designer who specifies the scope, methods and technology of the repair works is to ensure the building‘s safety of use and safety of its users while maintaining the conservation recommendations. The technical failure of the observation tower of the St. Anna’s Church, which took place after a relatively short period of time from the major overhaul of this facility, is presented in this paper. The scope of expert and design works as well as the scope for the contractor of the repair works, that are necessary to select the proper technological solutions for this case, are given. The diagnostics of the building carried out by the authors of the article allowed to properly determine the degree of damage. This ensured the suitable selection of the design solution and further replacement of the damaged cornice of the supporting structure of this historic church.

The building known as the Casa de la Cacica, seat of the Mixtec leaders of San Juan Teposcolula, Oaxaca, around the middle of the 16th century, exhibits the complexity of architectural and ideological interplay during the first period of colonization. The use of European techniques of construction did not prevent the native leaders of Teposcolula from conceiving of space and its political meaning in pre-conquest terms. Indeed, the new technology and architecture were probably adopted in order to legitimize and reaffirm the power of the ruling class in Teposcolula within the new context of Spanish domination.

Abstract: The initial dimensions and weight for the vehicle is considered from the Audi A8 vehicle as a reference. The specifications for the motor and battery are considered for the Mahindra e2o electric vehicle of similar dimensions. The main objective of this paper is to model and perform static analysis on the chassis of a four-seater car. The initial design for the chassis was a space frame body which is very rigid and had very less deflection. The second and final chassis is a ladder type chassis which is most common chassis type being used in Nepal and India. The difference in deflection between both the chassis type is very less, which is about 0.3235 mm for a reasonable reduction in weight which is about 120 Kg. The simulation part is carried out in ANSYS software. The result is selection of best suitable material for chassis on the basis of ANSYS and theoretically calculated result.

The frequent closure of roads for the sake of maintenance and refurbishment is an increasing problem for the road administrators and users, because of induced high costs, restrictions and influence they impose, traffic jam, and the many other disruptions such interventions have on traffic. In these circumstances, carriageways with long life span, with adapted tar, have much to offer, especially if they can exhibit optimum performances without requiring major repairs for over 30 years. On high traffic roads, research have shown that binders with elevated modules are a reliable and credible alternative to render their life span more sustainable and durable. In this context, the advantages presented by the absence of important repairs and refurbishing can be enough to justify the initial high costs of these advanced carriage way coatings. Studies on the different binders to be used were done, which have permitted in accordance with the performance of the layers, the required tests and the different study levels. Also, this has permitted us to analyze the obtained results and conclude that due to the expected needs, the LA and MDE tests, the PSV tests are the criteria that determine the selection of aggregates; The complexes modular methods, fatigue resistance (level IV), seem to be necessary for the forecasting of the mechanical behavior of bituminous materials.

Manuscript Copy

This chapter begins by introducing the most significant features of Scottish literary manuscript miscellanies, such as: their relatively late date, in comparison with surviving miscellanies from elsewhere in the British Isles; their copying by scribes who also functioned as notary publics, writers to the signet, and merchants; their links to some of Scotland’s most prominent book-owning families; and their inclusion of material derived from print and from south of the border. The remainder of the chapter offers a necessarily brief case study of one particular Older Scots literary manuscript miscellany (Cambridge, University Library, MS Kk.1.5) in which the Older Scots romance, Lancelot of the Laik, is placed alongside a selection of Scottish courtesy texts and legal material, a series of English and Scottish prophecies, several acts of the Scottish parliament, an English translation of Christine de Pisan’s Livre du Corps de Policie, and the only surviving manuscript copy of Sir Philip Sidney’s New Arcadia.

In this paper, the tangential zone of cartilage is introduced into the fiber-reinforced model of articular cartilage. Considering the distribution content of the main fiber and the secondary fiber in the tangential layer of cartilage, the permeability and fiber stiffness of the layer are set in parallel and perpendicular directions, respectively, to more accurately reflect the mechanical behavior of cartilage. The parameters are set to reflect the mechanical behavior of the cartilage more realistically. We use a modified articular cartilage model to simulate the mechanical properties of implanted cartilage with different elastic modulus. The simulation results show that the selection of implants with different elastic modulus will affect the repair of cartilage. Appropriately increasing the elastic modulus of implanted cartilage, can increase the bearing capacity of the repaired area and reduce the stress concentration at the junction. The elastic modulus of the implant should be moderate, not too large or too small, and the damage of stress concentration on the repair surface should be considered. Through simulation, the mechanical state of the repaired cartilage under pressure can be obtained comprehensively, which provides a theoretical basis for clinical pathology.

AbstractOver time, historic buildings are exposed to various destructive mechanisms brought about by a wide range of damaging factors. Costs and methods of reinforcing their individual components are, among others, an important issue. The term "reinforcement" is linked with the concept of conservation, which stands for the actions taken with the aim of preserving a building. It provides a well-articulated system consisting of activities that lead to the reinforcement of the structure, usability enhancement or to the improvement of its carrying capacity. This article analyses the selection of an appropriate brick pillar reinforcement method, taking into account accepted evaluation criteria.

Concepts of remedial treatments of historic buildings using ventilated floors, with a few exceptions, are with considerable popularity preferred by the representatives of monument protection. The fact that they require small interventions in the masonry is of great benefit for compliance with the methodology of cultural heritage protection, as is the fact that such interventions do not compromise the structural analysis of buildings. These concepts have gained great popularity also because they can be considered kind of a "return" to historical example. With these technologies we return to the methods and principles that the ancient Egyptians were already familiar with. The paradox is that these methods are used for many centuries, until today they are only proposed on the basis of empiricism. In this article two different underfloor ventilation systems are compared using CFD simulation.
