Calculation of the reliability of the slit foundation by the criterion of the bearing capacity of the foundation soil at the stage of operation There is brief information about crevice foundations, their advantages over traditional foundations. The main attention in this work is paid to crevice foundations for unique buildings and constructions. Special demands on safety of operation are presented to these buildings and constructions, that are contained in recent governmental documents and in standards. The method of foundation reliability calculations as it is one of the main carrier of the building. The calculation of foundation reliability was carried out on the criterion of load bearing capacity of the foundation for individual building or construction with limited statistic information about controlled options in calculated mathematic model of limit state on operational stage. With this statistic information probabilistic-statistical of reliability calculations, recommended with the existing standard can’t be applied. Due this foundation reliability calculations and crevice foundation residual time resource on operation stage predictions are offered. 10.18720/CUBS.57.1 624.151.5:642.046.5 the crevice base the bearing capability the basis the foundation reliability clutching with soil limited information https://unistroy.spbstu.ru/article/2017.57.1/ 1_utkin_57.pdf

Education in Construction area in Peter the Great Saint-Petersburg Polytechnic University The article presents data on work of Institute of Civil Engineering (ICE) with entrants and professionals. We make the study of international cooperation in Summer and Winter polytechnic schools. We explore the areas of interaction with enrollees: preparatory courses and "Academy of building". We conduct the comparison of the ICE with other universities in the Northwestern Federal District in admission to training bachelor and master degrees in Construction area in 2014-2016 years. In addition, the task was to show the information about International Polytechnic schools. We examine the programs of courses of retraining and improvement of qualification for employees. The study shows the major reasons of popularity of Peter the Great Saint-Petersburg Polytechnic University in the Construction area. 10.18720/CUBS.57.2 691.175.5/.8: 621.791.461 construction educational programs summer school entering the university SPbPU Institute of Civil Engineering https://unistroy.spbstu.ru/article/2017.57.2/ 2_gumerova_57.pdf

BIM-technology in bridge design Currently, construction projects are taking on an increasing scale. The spectrum of constructive and architectural forms of bridges is becoming wider, newest building technologies and materials are being mastered. Controlling and managing large-scale technological processes is impossible without using of computer technologies. As a result, BIM-technologies (Building Information Modeling) are widely used in construction field. The main purpose of this article is to research the innovative BIM-technology in the bridge design industry, as well as to disclose the problem of implementing BIM-technologies in bridge design. The article shows the possibility of collecting and systematizing all the data about the object, and managing of this information efficiently thanks to BIM technology. The example of the construction of the bridge over the Yangtze River revealed that the project implementation time is reduced by half, and maintenance of the finished object is much easier and more convenient also because of BIM application. Under of the set goal, such tasks as identifying the advantages and disadvantages of using BIM technologies in bridge design, as well as studying the factors that influence the transition to the use of these technologies in design organizations are solved. To achieve the goal, articles that fully revealed the capability of BIM-design, and articles reflecting the level of BIM-technologies prevalence in civil construction and certainly in bridge construction were explored. 10.18720/CUBS.57.3 69.003.13 BIM-technology design of bridge information modelling software innovation civil engineering buildings construction https://unistroy.spbstu.ru/article/2017.57.3/ 3_morina_57.pdf

Light Sources in Accordance with Their Quality Indicators and Energy Efficiency With a view to implementing the state policy in the field of energy saving and energy efficiency, steps are being taken to improve of engineering networks and communications in the St. Petersburg Polytechnic University. In particular, to determine the potential for increasing the efficiency of indoor lighting systems, a test was conducted using a luxmeter in the classrooms of the administrative building. It showed that the actual lighting indicators meet modern energy efficiency requirements and sanitary standards. Nevertheless, visitors with a long stay note the discomfort of the eyes. To determine the cause of this phenomenon the light sources characteristics were considered in detail that affect the visual workability and human health as a whole: emission spectrum, color temperature, intensity of light, daylight factor and light pulsations factor. A comparative analysis of the given characteristics of some light sources showed that conventional LED lamps are undesirable for long-term use because of the increased dose of blue light in the color spectrum of illumination. In the world market today there is a large selection of alternative light sources, domestic and foreign production, which differ in the work, power consumption, spectral composition of light. The article considers optimization problem of light sources choice for specific operating conditions, taking into account the simultaneous provision of quality indicators of artificial lighting systems and their energy efficiency. 10.18720/CUBS.57.4 69 buildings construction civil engineering energy efficiency energy saving artificial lighting illuminance measurement health protection luminous radiation https://unistroy.spbstu.ru/article/2017.57.4/ 4_kostenko_57.pdf
