Taking into consideration the survey findings, design specification requirements, architecturalplanning and constructive solutions, structure parameters and actual characteristics of materials the authors elaborate recommendations for reconstruction of corrosion-damaged structures of a canteen in Zaozerny village of Yevpatoria.

Computer modeling and numerical studies of nodal joints of frame structures

ALPATOV Vadim Yu., LUKIN Alexey O., SAKHAROV Andrey A., ZHUCHENKO Dmitry I. 19-22 p.

Sress-strain states of two types of nodes – MARKHI node and author’s node on sheet plates – are studied. Reliability of space structure nodes is analyzed with the use of modern computing complexes for structural analysis of mechanical systems. Computing complexes LIRA, Cosmos Works, DesignSpace, SCAD are used as research tools. Iterative processes of search for nodes rational geometry are organized. It is found that iterative search for nodes on the base of massive body should be organized by elimination of excessive material, but for nodes on sheet plates – by addiction of «missing» material. Prescriptions for rational design of both types of nodes are done.

THEORY AND HISTORY OF ARCHITECTURE, RESTORATION AND RECONSTRUCTION OF ARCHITECTURAL HERITAGE

Comparative survey of principles of conservation and restoration in international and Russian regulatory documentation and the question of the conservation of soviet avant-garde architectural heritage in Russia

BUSS Simon Christopher 64-69 p.

This article poses the question of the correlation of Russian legal and statutory regulation on the conservation of historical cultural heritage with the fundamental international charters, agreements and conventions. Comparative analysis of Federal Law No.73 of 2002 “On Objects of the Cultural Heritage (Historical and Cultural Monuments) of the Peoples of the Russian Federation” against 14 positions and principles previously defined in the author’s research of 6 of the fundamental international documents, describes both the general characteristics and areas of significant disparity in the approaches to the conservation of historical and cultural heritage. It is noted that the harmonisation of Russian norms with internationally recognised principles should render the conservation of soviet avant-garde architecture more effective, however the lack of a complete body of methodological guidance is a hindrance to this process.

SHUVALOVA Ekaterina M., KARAKOVA Tatiana V. 70-73 p.

The paper is devoted to the problem of evolution of table-ware color scheme in different periods, of correlation between color combination and culture aspects of one or another society, and of techniques of individual selection of color and color combinations in table-ware. The authors view compositional basis of design of welfare items – in particular of table-ware in different periods of arts and civilization development – and analyze the principles of formation and decoration of table set items. The analytic parallel is revealed between preferences in table sets choice and specificity of psychological processes of associative image formation at consumers.

In the article the reforms of city administration in the field of regulation of architecture and construction process in the second half of XIX – early XX centuries are discussed. In general course of reforms are determinative legislative materials, which became the base for the formation of new principles of territorial, sectorial and local control. During this period, the city becomes the focus of social problems, housing, transport, etc., requiring immediate measure solutions. For rapid response of the situation in the cities Central government transfers their powers at the local level.

Three orders approach in system of design composite method and process of its genesis

MALAKHOV Sergey A. 78-84 p.

In this paper the composite method is considered as methodology orienting modern design vision to solving the problems of environment crisis overcoming. This crisis caused by excessive pressure of capitalism pragmatic trends influences significantly on humanistic characteristics of architectural activities reducing design process to piece-work production that is indifferent to urban landscape and to modern culture ideal models. Three orders approach represents ethical and aesthetic variations of three types of world perception: traditional, vanguard and the worldview supposing invariant codes compromise. These codes revealing and their following fusion contribute to antipragmatic opposition to crisis.

Numerical investigation of influence of heat exchanger сhannel curvature on heat transfer

Менялкина Е.Н., Цынаева А.А. 134-138 p.

In this paper the influence of the curvature of the portion of the heat exchanger on heat exchange with the use of software systems Salome Meca and Code Saturne is numerically studied the verification of the numerical model by comparing with experimental data of other researchers without taking into account heat exchange is made. The solution is held for an average flow rate equal to 11 m/s. To investigate the influence on heat transfer of the curvature of the channel carried out the construction of the computational domain in the form of the heat exchanger of the same length with different turn radius. For discretization of the computational domain were used tetrahedral grids containing approximately 850 thousand of elements with local refinement near the surface of the channel. As a result of simulation values of the flow temperature at the outlet of the channels are obtained. It is revealed that the design of heat exchanger channel, of course, affects the heat transfer, as well as data on the applicability of different turbulence models for this type of task are collected.
