ARCHITECTURE AND URBAN PLANNING

9-21 834
Abstract
The paper presents extractions from works of philosopher Aristotles (384-322 BC) devoted to antic town planning. Aristotles’ ideas concerning the social structure of an ideal the Hellenistic state of the new type are considered the main part in which belongs to politicians and military elite. It is shown that Aristotles developed the program of the urban development (polies), sea ports and small colonial residences resembling military camps. This program included the analysis of the climate conditions of the region, the problems of defense and functional urban zoning.

Abstract
The paper considers the formation of new industrial cities in West Siberia of the First Five-Year Plan (1928-1932) during the interaction between regional conditions and architectural and town planning activity. The purpose is to identify regional features of the architectural and urban environment in West Siberia. A comparative analysis of archival materials of the late 1920s and early 1930s is presented for the formation of new West Siberian cities, namely: Novosibirsk, Barnaul, Kemerovo, Prokopyevsk, and Novokuznetsk. The comparison of Novosibirsk, Barnaul and Kuzbass cities shows general and specific features of the cities. The analysis of archival materials shows that regional architectural and town planning features in West Siberia of the First Five-Year Plan have been formed during the interaction of the departmental approach and regional conditions. In Novosibirsk and Barnaul, this interaction was organized by the regional authorities. On the contrary, in Kuzbass cities this process was uncontrollable and resulted in emergence of new problems of town planning.

Abstract
The paper presents a discrete model of masonry based on destruction mechanisms deduced from experiments and developed considering the contact interaction between base materials using interface elements introduced into the model. The proposed system of masonry strength criteria corresponds to biaxial stress state conditions, while design technology allows considering the structural modification of the model. Verification of the modeling technique and design technology is based on comparison of experimental results that allow the determination of the key role of elements providing the interaction of base materials during the elastoplastic deformation of masonry. The suggested discrete model of masonry and design technology cane be used in detailed examination of elastoplastic properties of piecewise homogeneous composites.

Abstract
The paper presents results of experimental research carried out into the static bending of reinforced laminated beam. The beam is reinforced with carbon tape placed in the two interlamellar bottom layers. Tests were carried out on a hydraulic press. Deformations and displacements online measurements are provided by the VIC-3D digital optical system based on the principle of correlation between digital stereoscopic images. Linear and shear strains are determined with the frequency of 1 Hz. The obtained images of the stress distribution of the visible beam surface reflect the stage of elastic and elastoplastic deformation. The possibility of using the VIC-3D digital optical system for determination and destruction of laminated beams is shown in this paper.

Abstract
The paper presents the quantification phase analysis of cement brick after a day of its natural hardening in the original state and after 15 and 25 cycles of magnetic activation of mixing water. The phase analysis is carried out using the Rietveld method. The energy computations of crystal lattices of Portland cement phases are provided to analyze the influence of magnetic activation on phase formation at cement paste hardening and the structural state of Portland cement components. Energies of Portland cement phase lattices are computed at 0 K at the initial stage of hardening (for one day). It is shown that the magnetic activation of mixing water has a considerable effect on the quantitative phase composition and the crystal lattice energy after 15 and 25 cycles of magnetic activation in comparison with the original state of cement system.
