Analytical description of the inclined crack trajectory by the method of nonlinear deformation model

Suvorov A. A., Filatov V. B. 14-18 p

The article proposes an analytical solution to determine the trajectory of inclined crack with the use of nonlinear deformation model in the area of the transverse bending of a reinforced concrete beam. The use of nonlinear deformation model for the analysis of stress-strain state of the beam in the zone of the transverse bending allows to determine the coordinates of the inclined crack trajectory, the position of its vertex, and the angle of inclination to the longitudinal axis of the beam. It is then possible to move from the empirical dependences for calculating the strength of the inclined sections to precise analytical techniques. The proposed algorithms calculate and analyze the stress-strain state of reinforced concrete beams create preconditions for the implementation of the physical model of a power resistance of reinforced concrete elements under transverse bending.

Composite method: mega-object model updating? its value and procedures

Malakhov S. A. 72-79 p

The paper discusses the concept of mega-object, which is a review of the relationship between the object and the environment from the perspective of enhancing specific individual actions of the designer. The central aspect of this conception is an individually executed model of an urban landscape fragment, which is one of the key subsystems of the environment. The first thing that this model does is to achieve the plastic integrity of the form of an environment fragment. As a result, from the perspective of this concept, some single object cannot be fully effective without being an integral part of this whole. All modeling procedures developed in the composite method introduced by the author are subordinated to the idea of assembling or cutting the body of mega-object. The composite method here serves as an organic link to art, first of all, to plastic art. The article emphasizes the importance of Frank Lloyd Wright’s activities as the founder of an organic architecture, gives a classification of mega-objects and describes how they are dependent on the so-called “Size scale” of the composite method design.

Strategies for anonymous and professional languages interaction in design practice

Repina E. A., Romanova D. N. 95-101 p

The paper demonstrates values of an anonymous language and its potential for design practice. It attracts attention to the problem of unprofessional architecture which is underestimated in professional practice. The thing is that squatter development is usually seen as a product of poor architecture and is widely destroyed and replaced by typical unified objects. The question of the legitimacy of such project invasion is raised in the paper. It puts forward a methodology for working with anonymous languages and demonstrates how to do taking the so-called “Red houses” (districts within Cheremshanskaya – Nagarnaya – Voronezhskaya – Kalinin streets and Rotorniy alley) as an example. The paper covers issues which were faced during the work. It takes three projects – that is “Municipal Design”, “Public design” and “Custom design” – as examples and explores strategies of the design “intervention” of a professional architect and ways of dialogue with the environment on the language level.

Solodilov M. V., Korobova E. S. 117-123 p

The article describes the background of the principle of architecture and monumental arts synthesis that emerged in the domestic version of modernism in 1960s. It mentions artists and architects who contributed to the modernist architecture enrichment with artistic and plastic tools. The influence of Moscow monumentalists who worked all over the USSR improving the image of young Soviet cities is stressed. With Toglyatti as an example, the paper demonstrates different ways how the principle of architecture and monumental arts synthesis might be applied and also discusses the principle of a single urban design plan that emerged in Soviet architecture. The authors describe construction objects built according to this principle, give glimpses of biographies of artists. The given details are based on the previous archive studies. They also provide possible reasons for the decline in monumental art and predict the emergence of modern forms of art that would interact with architecture. Objects, to which the principle of architecture and monumental arts synthesis might be applied, become a potential and an internal resource for tourist and cultural attraction of the city.

Centralized heat supply system and techniques of planning its loads

Chicherin, S. V., Glukhov S. V. 129-136 p

The paper analyses heat-supply systems of four major Russian cities and heat-supply regulatory documents. The authors investigated company documents providing information on construction objects prospective connection and on unconnected consumers for each heating season. The information contained in the documents was summarized and made anonymous to preserve confidentiality of consumers. The researchers also studies data from the official site of the Municipal Service Department of Omsk Administration. The data showed housing stock structure and its coverage with centralized heating services. The following percentage rating for reasons causing the thermal load removal is detected: thus, 31 of 47 construction objects with a total load of 80.8% (of the total load removed during the period under review) were switched off the system because of “The resettlement program for citizens from the emergency housing stock” in 2016. Typical problems of a large settlement centralized heating system operation are also described in the paper. It is shown that there is a tendency towards a significant increase in the amount of annual heat consumption decline underway. This increase in decline may be 32-multiple in some regions, and it may go slow in the others. Making recommendations based on the results of the design calculation will clarify diameters of trunk and intra networks, which the authors see a task for the future. In general, this methodology should help to adjust industrial strategies for consumer needs.
