Constitutive Parameters

With the aim of evaluating local and global dynamic mechanisms of a vast and historical masonry building, a homogeneous structural model is proposed here. It is realized with the assembly of othotropic plates and Timoshenko and pure shear beams as well. The identification of the constitutive parameters is carried out after realizing refined finite element models of building portions, and imposing energy or displacement equivalence with the corresponding homogeneous versions, depending on the complexity of the involved schemes. The outcomes are compared with those provided by experimental investigations, and help to give insight and interpretation on the dynamic behavior of the building.

The historical masonry buildings are characterised by a great vulnerability regard the seismic action, as the recent events occurred in Central Italy have highlighted. During the seismic emergency the authors, in collaboration with the Civil Protection Department as part of the ReLUIS activities, have carried out usability inspections, analysing also the case study described in this paper. The structure, a school in Teramo, was already affected by previously seismic damages and it has been highly involved by the seismic events abovementioned. In this work the results of first inspection, reported in the AeDES form, and a more accurate visual inspection are presented in terms of detection of the crack patterns and evaluation of the seismic damages index. Moreover the vulnerability index has been calculated according to the GNDT 2° level method. The vulnerability index is finally used to calculate the damage index expected for the seismic intensity registered during the seismic event of October 30, 2016, and compared with the observed post-seismic damage level.

Historical Masonry

Masonry buildings are ordinarily complex construction systems and there is a lack of knowledge and information concerning the behavior of their seismic response. Due to the life safety of masonry buildings under seismic effects are very essential, numerical modeling and analysis of the buildings are an important issue. Because of the insufficient seismic resistance on structural members such as jack arch slabs and masonry walls, numerical studies have become necessary to determine the level of the structural strength of the structures. The tensile strength of load-bearing walls in the buildings is lower whereas, the compressive strength is higher. In this way, tensile cracks occur at structural members due to insufficient tensile resistance. Therefore, the tensile stress locations in the structure are critical. The study focuses on the assessment of historical masonry buildings from the point of seismic resistance. The entire process is performed using a case study from a historical masonry building. In this study conducted in this respect, the existing situation of a historical building using numerical analyses were presented with the cross-disciplinary study of civil engineering and architecture. The linear elastic analysis is selected as an analysis method. The seismic parameters are determined based on the Turkish Earthquake Code (TBEC 2018). Consequently, the study is performed to determine the seismic-resistant of historical buildings within the scope of numerical analyses.

The long-held notion that Bartók’s style represents a unique synthesis of features derived from folk music, from the works of his best contemporaries, as well as from the great classical masters has resulted in a certain asymmetry in Bartók studies. This article provides a short overview of the debate concerning the “Bartókian synthesis,” and presents a case study to illuminate how an ostensibly “lesser” historical figure like Domenico Scarlatti could have proved important for Bartók in several respects. I suggest that it must almost certainly have been Sándor Kovács who called Scarlatti’s music to Bartók’s attention around 1910, and so Kovács’s 1912 essay on the Italian composer may tell us much about Bartók’s Scarlatti reception as well. I argue that, while Scarlatti’s musical style may indeed have appealed to Bartók in more respects than one, he may also have identified with Scarlatti the man, who (in Kovács’s interpretation) developed a thoroughly ironic style in response to the unavoidable loneliness that results from the impossibility of communicating human emotions (an idea that must have intrigued Bartók right around the time he composed his Duke Bluebeard’s Castle ). In conclusion I propose that Scarlatti’s Sonata in E major (L21/K162), which Bartók performed on stage and also edited for an instructive publication, may have inspired the curious structural model that found its most clear-cut realization in Bartók’s Third Quartet.

The research is actual, has a theoretical and applied nature. Theoretical developments at cost management branch of economic organization were illustrated by practical examples. In the work the follow methods are used: abstract-logical, methods of induction and deduction, system and situate approaches, methods of comparative analysis, analysis of breakeven, monographic analysis. The follow sources of information were used: literature, the results of the experimental investigations, carried out in Verkh-nevolzhsky Federal Agrarian Research Centre, observations, carried out at an agricultural organization. Theoretical structural model of cost management was created in a functional way, relationship between elements were designated in it, as well as driving forces of its realization were determined. Such terms as “cost management ” and «management accounting» were specified. The paradigm of a relation to cost process was described. Approaches to realization of cost management system of organization on the basis offlexibility principle were developed. The most important of them are: application of applied programs packages and special program means for computer, organization of feedback, account of functional relationship of cost with production results, cost accounting on elements, places of origin, carriers and centers of responsibility, as well as interactive approach. Some examples which show possibilities of using some instruments of cost management and management accounting for generation of management solutions were described. These instruments are: analysis and planning on the basis of standards of constant and variable costs and flexible cost management in interrelations to other subsystems in management system of organization (in this case it is with technology management. The work is of theoretical and practical significance.
