 Smart home as a factor of the transformation of construction With the development of information technology in modern buildings begins the introduction of smart home systems. At the same time, such systems are practically not investigated from the standpoint of building science. To identify emerging, in this regard, areas of expansion of the construction sector potential, an analytical review of existing studies was conducted. The review included research related to the structure of the system and UI, with an estimation of economic efficiency and possibilities of use, including several analytical surveys from the standpoint of specialists in the field of information technology. There were several areas that can be used in the design and construction of buildings. The directions for further research of smart home systems, including the connection with BIM-design and construction organization, development of a universal model of the basic system and the development of new approaches to the design of architecture, structures and engineering systems, are also proposed 10.34910/ALF.5.1 69 smart home automation smart city modular approach technology voice control implementation of smart home system home control https://alfabuild.spbstu.ru/article/2018.5.1/ 1_5.pdf

 The quadratic approximation in nonlinear theory of rods This article is about the nonlinear theory of elastic rods (Cosserat-Timoshenko rods). This theory uses bending stiffness, shear stiffness and tensile-compression stiffness and there are not any limitations for movements and rotations. Equations of quadratic approximation were derived. The variational formulation of problem as the search for the stationary point of the Lagrangian functional for quadratic approximation was given. The coherence of equations of quadratic approximation with variational formulation was approved in this article. The border conditions of this problem for quadratic approximation were given. The examples of solution of the problems in nonlinear theory are given in this article 10.34910/ALF.5.2 69.04 nonlinear theory of rods theory of Cosserat-Timoshenko’s rods variational formulation geometrically exact theory geometrically nonlinearity Lagrangian functional stiffness of rods functional https://alfabuild.spbstu.ru/article/2018.5.2/ 2_5.pdf

 Constructions of high-rise buildings At present, experience shows that in large cities the construction of tall buildings is increasingly developing due to the high cost of land, scarcity of urban areas, intense population growth and other reasons. Construction of high-rise buildings has its own specifics in terms of a three-dimensional form, proportions, selection of structural systems and elements of buildings. The main issue in the design of tall buildings is to ensure the reliability. Therefore, the construction of such facilities requires the use of a completely unique engineering solutions. Given current trends of high-rise construction, the article gives the classification of structural systems (circuits). Considered are the main supporting structures of tall buildings. Based on the analysis of literary sources, the description of some engineering solutions, which found itself in the construction practice 10.34910/ALF.5.3 69 High-rise buildings structural systems mega column (mega frame and space truss) systems tube-reind concrete high-rise construction unique construction compositforcee materials,outriggers https://alfabuild.spbstu.ru/article/2018.5.3/ 3_5.pdf

 Industrial waste and MSW in road construction Currently, the question of durability of asphalt concrete is an important problem because of the high cost of construction and production of construction materials. The aim of this study was to determine the degree of influence of various additives (such as viatop 66, filler, asphalt, particles, drill cuttings) on property and the cost of the asphalt mixture. The study was conducted by means of analysis of published articles, Construction Norms and Regulations and patents. As a result of this project it was found that additives can significantly alter the properties of concrete such as density, strength. Supplements are cheap raw materials, so the economic benefit is 80%. Using the above-mentioned additives will make the construction of the roadway will be cheap and very effective. In accordance with the previously conducted research supported the hypothesis that the use of Industrial waste and MSW in road construction makes the construction of 80% more profitable and increases the quality of the asphalt mix. 10.34910/ALF.5.4 625.7/.8 Recycling roads bitumen concrete building materials construction wastes сivil engineering https://alfabuild.spbstu.ru/article/2018.5.4/ 4_5.pdf

 Protection of trade secrets in construction companies The main issue of protecting confidential information is the desire of third parties to obtain this information for their material benefit or to obtain a worthy place in the market. The reliability of preserving confidential information often depends not only on the fate of the enterprise, but also on the safety of business organizers. The purpose of this article is to identify objects that are protected in the mode of commercial secrecy in construction companies, as well as to consider existing methods for their protection. The analytical method established that the best protection of information requires the introduction of a system of measures to preserve trade secrets, which include determining the list of confidential information, restricting access to it, as well as regulating relations for its use. The study showed that the high importance of trade secrets for successful work on the market forces entrepreneurs to pay close attention to information security issues. Refusal to comply with the regime of commercial secrecy can cost the company much more than the payment of security personnel and the purchase of special equipment 10.34910/ALF.5.7 69 Intellectual property trade secrets process safety management data privacy privacy rights laws and legislation information leakage construction company https://alfabuild.spbstu.ru/article/2018.5.7/ 7_5.pdf
