 Load-carrying ability of adhesive joints in suspended facade constructions In this article the type of fastening translucent enclosing structures using a structural silicone sealant is considered. This kind of glazing is called structural glazing. This is the method then glass is glued directly to the metal frame which is attached to the bearing structure of the building. All loads applied to the facing are transferred to the binder, the silicone sealant, which must maintain a long-lasting adhesion and integrity throughout the lifetime of the building. The paper considers the main points that must be taken into account in this type of structure design process and the course of calculation of the geometrical parameters of the adhesive joint based on EOTA ETAG002 is presented. 10.18720/CUBS.68.1 69 structural glazing; silicone adhesive; fixation; glass; façade; adhesive joint; translucent structures; suspended facade; load-carrying ability; construction; https://unistroy.spbstu.ru/article/2018.68.1/ 1_68.pdf

 Renovation of apartment buildings in Russia The existing housing stock of the Russian Federation makes 3.6 billion m2 (2016). The area of apartments is about 25 m2 per one person. About 50% of houses in Russia need renovation. The considerable part of housing stock was constructed during an era of industrial housing construction. Many buildings of the first mass series have high strength characteristics. However, thermal comfort of these buildings in most cases unsatisfactory. Taking into account that the heating season in Russia on average lasts from October until April, the specific heat consumption for heating and ventilation during the cold period is 150—200 kWh/m2 per year for non-modernized buildings. This paper demonstrates the results of the investigations based on the field study and calculations of the thermal performance indicators of the standard residential building made of many box units (HDD = 3925 K*day/year).

According to calculations, after thermal modernization of buildings the level of specific heat consumption for heating and ventilation will decrease twice. In this case, the building will approach to the low-energy building standard. This study provides calculations of required R-values of building elements for residential buildings at the renovation in cold climate of Russia. The optimal insulation thicknesses must be calculated for each region to make the energy efficient building. Implementation of highly insulated building envelope allows use of renewable to partly cover heat consumption. The results indicate that it is economically feasible to renovate high-energy houses in cold Russian climatic conditions. The period of the cover expenditure of thermal renovation measures of buildings of the first mass series according to the accounting estimation is about 10—12 years. Such low-energy buildings have added good indoor environment, long lifetime, higher market value as well as they are environmentally friendly 10.18720/CUBS.68.2 69 apartment building; environmental benefit; thermal comfort; energy performance; envelope; thermal insulation; renovation https://unistroy.spbstu.ru/article/2018.68.2/ 2_Kornienko_68.pdf

 Trial design of the large-span structure In the article the results of the investigation of the stress-strain state of the large-span dome of the "Bolshaya" ice arena of the city of Sochi in the conditions of Novosibirsk are considered. In the course of the study, two versions of the coating modification were proposed and a comparative analysis of the solutions was carried out. Based on the studies carried out, a criterion for optimizing the structural solutions of metal structures has been selected. The results of the search for a rational geometric coverage scheme by the criterion of conditional metal consumption are presented using SCAD Office. As a result of the research, two optimal constructive schemes for covering the main part of the ice arena were found. 10.18720/CUBS.68.3 69 large-span structure; SCAD Office; space frame; rational shape; metal consumption; trial analysis https://unistroy.spbstu.ru/article/2018.68.3/ 3_Demidova_68.pdf

For volumes from 10 thousand m3 or more, it is recommended to arrange tanks in two rows. In design standards, recommendations are given to account for wind load only for a stand-alone tank. The authors of the article studied the distribution of the wind flow and its effect on the stressed state of the spherical roof of a steel vertical cylindrical tank with a volume of 20,000 m3 . Variants of wind pressure per tank and a group of tanks were considered. For the considered variants, aerodynamic coefficients are obtained in the SolidWorks Flow Simulation software package. To verify the coefficients obtained, a physical experiment was performed on a reduced tank model in a wind tunnel. The stresses in the elements of the spherical roof of the tank were determined by the finite element method using the “SCADOffice” calculation complex. As a result, differences in the standard distribution of wind pressure from the experimental one for a single tank and located in a group were revealed. The most unfavorable version of the distribution of wind pressure for the tank in the group was determined. The stress-strain state of the tank roof is compared with the standard and experimental wind load for the most unfavorable variant. 10.18720/CUBS.68.4 69 wind tunnel vertical cylindrical tank globe roof aerodynamic factor stress-strain state https://unistroy.spbstu.ru/article/2018.68.4/ 4_Mushchanov_68.pdf

However, up to the present time, problem of recognizing damages and predicting their emergence is still far from being solved. This article suggests a method of damage recognition, based on the analysis of monitoring data on the technical condition of building structures. The method considered in the article is based on the matrix analysis of information coming from the sensors using a movable fractal. The practical application of the proposed method is illustrated on the computer model of a real high-rise building. The carriedout researches show that the method of the movable fractal allows to uniquely identify the appearance of defects in load-bearing structures. 10.18720/CUBS.68.5 69 monitoring of technical condition building structures sensors damage fractal https://unistroy.spbstu.ru/article/2018.68.5/ 5_Ryabtsev_68.pdf

 Methods improvement of technological and price audit for construction investment projects Conduction of technological and price audit is an obligatory procedure for investment and construction projects with state participation. This audit should help minimize the financial costs of budget money. However, the analysis revealed serious shortcomings in the methodology. The aim of the work is to improve the existing methodology at the first stage of the technological and price audit - a feasibility study. The tool is a method of expert assessments, with the help of which the partition weights are calculated. Each section has a different influence of error probability on cost, which is also taken into account in the work. Also, the work suggests criteria for calculating the effectiveness of the project. On the basis of calculations, a mathematical model of the result of technological and price audit was created. 10.18720/CUBS.68.6 69 expert review weight coefficient technological audit price audit construction investment project https://unistroy.spbstu.ru/article/2018.68.6/ 6_Kutsenko_68.pdf

 Actual thermal insulation properties of cellular autoclave curing concretes Results of laboratory researches of the wall not reinforced products from cellular concrete of autoclave curing (gas-concrete blocks) are presented. The actual thermal insulation properties of the cellular concrete cut from product samples of three producers in most cases don't coincide with the values declared producers and presented in the standards prepared with their direct participation. The discrepancy of calculated and actual values of thermal conductivity of the materials and products used at the device of the external protecting designs leads to increase in heat losses through walls and to an over expenditure of specific heat consumption of heating system. In this regard cardinal revision of the values declared producers and also standards on the basis of which 10.18720/CUBS.68.7 69 aerated concrete blocks density thermal conductivity water vapor sorption vapour permeability vapour permition resistance exterior walls heat transfer resistance energy saving energy efficiency https://unistroy.spbstu.ru/article/2018.68.7/ 7_Gorshkov_68.pdf
