Thermal analysis of laminated composite and sandwich plate using layer wise finite element In this paper the quasi static response of laminated composite and sandwich plates subjected to lineary varaying through the thickness and sinusoidall distributed in plane temperature field, is analyzed. Mathematical model, based on layer-wise displacementfield of Reddy, is formulated using small deflection linear-elasticity theory. The principle of virtual displacements (PVD) is used to obtain the weak form of the mathematical model. The weak form is discretized utilizing isoparametric finite elementapproximation. The originally coded MATLAB program is used to investigate the influence of plate thickness on thermo-elastic response of laminate composite and sandwich plates. 10.18720/CUBS.20.1 69 thermal analysis layer wise model composite plates finite element https://unistroy.spbstu.ru/article/2014.20.1/ 1_murgul_20.pdf

Smart Buildings Using IoT Technologies The need for remotely accessible data and information/knowledge about technical performance of buildings, at any time, from any place, regardless the type of parameters, together with the need of complete remote control will lead to the development of “Internet of Things” (IoT) for buildings. “Intelligent Buildings” (IB) are envisaged by this technology in order to optimize their performances over the life-cycle. A solution regarding to the architecture of an IoT network for IB and an experimental testing bench for one of the first steps leading towards implementing the IoT for integrating components and subsystems of IB and networks of IB is briefly introduced in this paper. An overview about IB and future trends in this sector is introduced in the first part of the paper. Current developments on IoT are further highlighted. A generic architecture of IoT and the way it could be implemented into intelligent building systems are afterwards presented. Implementation and testing of the solution for connectivity between a distributed network of smart components of IB and an Android compatible monitoring device covers the next part of the paper. Tests have shown that the proposed concept is functional. Paper ends with conclusions, as well as with the roadmap for concept implementation. 10.18720/CUBS.20.2 69 intelligent buildings building automation internet of things system life-cycle network-integrated systems smart components wireless control https://unistroy.spbstu.ru/article/2014.20.2/ 2_brad_20.pdf

The defects of protective facing masonry of frame buildings Widespread use of the sandwich walls in frame buildings in Russia is the result of high requirements to energy efficiency of the coating constructions. The defects of facing masonry were caused by insufficient level of experience at the processes of design and construction of such kind of buildings. The purpose of the article is to describe the main causes of the defects of facing layer of sandwich walls. Conclusions about the rationality of the cellular bricks with the results of experimental work are also shown in the paper. 10.18720/CUBS.20.3 69 brick masonry defect sandwich walls masonry anchor movement joint cellular bricks mason's mortar https://unistroy.spbstu.ru/article/2014.20.3/ 3_zimin_20.pdf

Thermal performance elevation at Sergey Radonezhskiy temple reconstruction in Volgograd The priority direction of modern architecture and construction is energy efficiency and energy saving. Thermal performance elevation and thermal comfort indoor climate supporting are necessary during all life cycle of the building — at design, construction, operation and reconstruction of buildings. This problem is especially actual for the cultural heritage objects which are of historical and architectural and art value. Preservation of the history and the cultures monuments which are national property, it is important both for present generation, and for descendants. In this article the thermal performance elevation problem solution at St. Sergey Radonezhskiy temple reconstruction in Volgograd is given. On the basis of visual and tool inspection numerous defects of external walls of additional building to the temple by construction which can't provide reliable and safe conditions are revealed. The assessment of hollow masonry thermotechnical parameters by use of temperature and moisture mode method with consideration for edge effects zones is executed. By results of calculation it is established that application according to the design as mineral wool insulation provides minimum admissible requirements for thermal performance. However the lowest value of heat transfer performance uniformity factor testifies to the inefficient design constructive consideration of external walls. The settlement assessment showed that application of monolithic polysterene concrete, according to the author idea, considerably increases the heat transfer performance uniformity factor of external walls. The specified recommendation is realized in practice in 2013. 10.18720/CUBS.20.4 69 orthodox temple enclosure structure thermal performance thermal comfort reconstruction https://unistroy.spbstu.ru/article/2014.20.4/ 4_korniyenko_20.pdf

There are a lot of methods to stop icicle formation on the roofs. But most of them are in need of expensive and complex equipment. At present article is used a way of stopping forming ice dams by creating a "cold attic". Tehnique of a transient air hole was offeredto make it. The transient air hole can change its section area depending on wind speed. Such a constriction allows entering into the attic a bigvolume of cold air. Also, it helps to prevent a noise which is provided by a usual air hole. This concept was confirmed by a heat balance of the attic. 10.18720/CUBS.20.5 69 icicles air hole attic roof space ice dam snow melting https://unistroy.spbstu.ru/article/2014.20.5/ 5_suslova_20.pdf
