The paper is devoted to the creative heritage of notable Catalonian architect Josep Puig i Cadafalch (1867-1956). His creative biography and three styles are described, in which he was engaged in different periods of life. The first style is Catalonian modern (Modernisme) was used to create Casa Marti (Cafe ‘4 Cats’, 1895-1896), Casa Amatller (1898-1900) and Casa Terrades (1903-1905). The second style is rationalism (Casa Trinxet, 1904; Casa Muntades, 1901). Тhe third style neo-classicism (Noucentisme) was used to build Spain credit bank and Casa Pich i Pon, 1919-1921.

The paper presents the unexplored issues of housing reform undertaken by Khrushchev. It is shown that this reform fundamentally changed the character of the settlement due to the replacement of collective housing by the individual one and the restructure of distributing the state budget from the military to civilian (housing) sector. The paper poses problems and outlines the research program of the Soviet housing policy of Khrushchev era.

In the 30s, the authors of Tomsk layout adhered to the city studies approach. They analyzed examination materials collected in Tomsk archives. The paper presents the most important problems of city development and a set of architectural and planning measures taken in Tomsk that time. A study of the city plan allowed including the architectural heritage in the project, such as engineering constructions and landscape objects. This allowed saving money, while the city image accepted its individual traits.

In article historical prerequisites of formation of a complex of city hospital of Krasnoyarsk in XIX - the beginning of the XX century are considered. The historical and cultural value of the objects which are now in the territory of the former city hospital is shown. Expediency is defined and the principles of their restoration, preservation and inclusion in activity of the modern city are offered. Results of the analysis of historical graphic and text documents, on-site investigation of objects of a complex, the design concept reflecting a demand of the offered functions and feature of their realization are presented.

The structural analysis is given for Orthodox architecture in West Siberian. The past experience is generalized and characteristic features of churches are investigated herein. The total results are given in relation to the development of architecture in West Siberia. The notions are suggested for architectural styles used in this region.

(brief historical review) The history of the optimum design development dates back almost four centuries. During this period, approaches to the problem of optimization have been changed, new methods of their solution appeared, purpose functions and constraints of this problem have been specified more accurately. The process of the problem development is rather instructive, as it shows some general trends in scientific and technical creativity as a whole. This paper is not fully exhaustive. Moreover, does not contain recommendations related to specific types of structures (except for the pioneering works). The main attention is paid to the development of «instrumental component» of the optimum design and ideology of the problem.

The paper presents experimental research of hollow masonry fragment under static load. VIC-3D digital optical system is used to detect lateral surface deformations using the correlation technique of digital images. The main stages are detected for the masonry fragments. The values of the elasticity modulus and stresses are obtained for all stages of masonry behavior under centris and eccenrtic loads.

The paper presents the analysis of known calculation techniques related to the allowable damage factor. This technique is based on accounting for different stiffness of elastic and elasto-plastic systems. A method is suggested to detect the maximum permissible level of plastic deformation of a structure. The analysis of the proposed methodology of determining the allowable damage factor confirms that the popular construction materials (masonry) values can be obtained that ensure the correct reflection of the structural plastic deformation under seismic loads.

This paper presents the main bolt connections known today and formed by reciprocal punch. The results of experimental and numerical research are presented for slender section connections by reciprocal punch of connected elements using sets of washers that meet the state standard requirements. The optimum compositions of washer sets are detected for steel sheets 1.5 and 2.0 mm thick using M10 and M12 screw connections. The effect from the set of washers and the quality of connections are shown in this paper. The further research directions are described for the problem of the efficient use of this connection type.

The paper presents the results of reinforced concrete beams tests with precracking at a specified located distances from supports, in the center of the span and above the reinforcement bars. The values of deflections and relative deformations of compressed and tensile zones are compared with the beams where cracks are formed stochastically. It is shown that crack forming plates locate both in the maximum torque zone and beyond it that reduces the beam deflections.

The paper presents theoretical and experimental results on silicate melt processing using the low-temperature plasma. The temperatures of complete melting are detected for the materials under research. The silicate melt production is characterized by the simultaneous melting of all phases at a heating rate of 1000 °С per second unlike the processes occurred at usual heating rate of 0,5-1 °С per second. As compared to the existing technologies, ultrahigh heating rates 2-2,5 times reduce the time of formation of heterogeneous melt and specific energy costs (1,5-2,1 kW/kg).

The paper presents a composite binder obtained by co-grinding of cement (55 %), ash acid composition (40 %) and limestone (5 %) having the specific surface area of 550 kg/m² and 77,3 MPa activity. It is shown that the combined influence of mechanical activation increases the pozzolanic activity of acidic ash and has a catalytic effect on the surface activity of ash and sand. The addition of fly ash and crushing limestone waste into the composite binder decreases water and gas permeability of concrete. The composition of fiber-reinforced concrete based on a composite binder is suggested herein. 1,6 % steel reinforcement with hooked end fiber, the maximum mechanical-and-physical properties can be obtained (100,9 MPa). The obtained concrete provides an effective diffusion coefficient allowing its use in buildings contacting with highly aggressive environments, such as underground engineering structures. Rather a low water absorption of material and low water vapor permeability can be explained by the porous structure of the cement brick.

A comparative estimation is given for the numerical calculation results and field tests.

The paper presents with the problem of the energy dissipation of oscillatory processes within the internal and external boundaries of deformation. The dependency is obtained for the oscillation dissipation rate and the shear angle of stress vector and deformations. The Voight hypothesis allows constructing the dependence between the internal resistance and the rate of the system displacement. The problems of the system flexibility at the elastic and elasto-plastic stage are considered in this paper using the Karman principle. The conditions of the dissipation factor are identified for the bridge span beams at a stage of their dynamic loading.
