The paper describes the unique trend in the world architecture - Catalonian modern (Modernisme). The historical and political, socioeconomic and cultural premises of this style rise are considered herein. For Catalonia, Modernisme has become the renascence symbol of national identity. The general plan of the capital of Catalonia was made by Idelfonso Serda in 1872. It is shown that district L'Eixample in Barcelona is the original experimental polygon for creative work of the outstanding Catalonian architects late in the 19th and early 20th centuries.

The paper describes the architecture of the Regiment buildings constructed in Barnaul in 1906-1909. Historical aspects of construction, accommodation in urban areas, planning structure of buildings are described as well as the typology, architectural and planning solutions and building styles. Field investigations are carried out, the literature review is given, and plans of Barnaul and archival documents are presented in this paper. It is shown that the buildings of the Military establishment are built in the southern part of the city. They fit the environment and are self-contained. Buildings are constructed in one style. Planning corresponds to the building functional purpose. It shown that the object under study belongs to the state building of the beginning of the 20^th century.

Architects use various systems of proportion as an instrument for harmony achievement. Although these systems are significantly differ from each other, the idea of the architectural object similarity to a living organism is their genetic origin. In Antique Greece, the attempts to generalize the long-lasting observations and the human interest to his own functionality led to positive results in creating invaluable works of art and engineering including the architectural order. Antique Greeks gave a great lesson to future generations of architects demonstrating the possibility of creating functional and wonderful things by the means of their behavior similar to that of man.

The paper presents the analysis of general concepts of the contemporary methodology and control for the polycentric spatial planning in the world. The experience of European and post- socialist countries is considered herein. It is shown that the polycentric spatial planning has the effect on the average time expenditure of the population that is connected with the insufficient diversification of workplaces that, in turn, is connected with unconformity of the local labour base with needs of local population. The paper gives a forecast for the development of research trends in relation to polycentric spatial planning in the largest cities of Russia and in West Siberia in particular.

The article presents the historical analysis of the of architectural urban development in Tomsk in the 17th - 20th centuries. The implementation features are given for time transgressive urban development. The town planning pattern, established by the end of the 20th century is compared to the historical design and overall plans. The importance is shown for pre-regular town planning pattern of 17th century during the architectural replanning on a regular basis. For the first time presented is the alteration of the pre-regular Tomsk planning combined with the topography of the construction survey of the year 1933. The effect of the city planning government policy on the urban development is shown under conditions of considerable distance barriers of the region outward the capital city. Moreover, the analysis is given for urban alterations of the 20th century in the context of the historical development of the planning pattern.

This paper presents the wear analysis of disk-ball couple element lubricated with mineral oil and zinc ultrafine particles modified with this oil. Friction couple elements are produced from different hardness structural 0,8 % carbon steel. In modified oil lubrication of the coupled elements with tempered steel disk (63 HRC), the width of the wear path increased by 20,5 % comparing to non-modified lubricant. Another situation is observed for the friction couple with the thermally non-treated disk (185 HB). The use of modified oil particles reduces the wear path by 10 %. The lubricating effect is explained by the interaction of zinc particles with lubrication oxygen and mechanical deformation of these particles that appear on the friction surfaces.

The results of theoretical research of reinforced concrete slabs supported along four sides on yielding supports under the dynamic loading are presented in this paper. The research allows estimating the degree of rigidity of yielding supports, deformation stages, rigidity distribution by the plate perimeter and the level of deformations of yielding supports during the transition to plastic deformation that influence the behavior of reinforced concrete slabs. The results of calculations allow the detection of mechanical-and-physical properties of supports and, thereby, achieving the maximum effect from the decrease in stress-strain state parameters of the structure.

The research is carried out into the possibility of using the computational algorithm for the synthesis of design solutions for steel structures. The dependence between the truss span and the actual load and the optimum height and minimum mass of the truss is described in this paper. Graphical dependences are obtained to show the change in mass and cost of the structure. The dependence is determined between the cost of the structure and the types of steel and section. The suggested algorithm is based on CAD information technology for the industrial steel structural design solutions and implemented as a subsystem of automated design.
