 The economic efficiency of replacement of old heating pipes in St.Petersburg The heating pipelines are the most vulnerable element of district heating system. The average service life of heating pipelines which were built in the Soviet Union does not exceed 15 years. Every year in St.Petersburg 230 km of heating pipes in one pipe calculation goes up in the category of network that has reached the passport life (25 years). Reconstruction of old heating networks with installing new pipelines in polyurethane foam insulation will reduce heat loss significantly. In the article the economic efficiency of the reconstruction of district heat networks calculated. In accordance with the scheme of heat supply by 2030 planed to renovate 163900 m of heating pipelines (819500 m in the double-pipe calculation) dilapidated heating networks owned by the "St. Petersburg Heating" JSC. 10.18720/CUBS.34.1 69 heating networks reconstruction economic efficiency https://unistroy.spbstu.ru/article/2015.34.1/ 1_petrakov_34.pdf

 Acceleration of the formation process of the structure of cement stone with the use of carbonnanomodified additives It is possible to trace the relationship of influence of various additives on the kinetics of cement hydration by exothermic effect produced by hydration and wetting of cement. Identifying additives which produce inhibiting or accelerating effect on the process of setting and hardening allows to predict their impact on the growth of strength. The activity of influence of additives can be assessed by the use of thermo-kinetic analysis method. In this article the calorimetric study of the influence of cement-carbon material was conducted. 10.18720/CUBS.34.2 69 nanomodified additives cement-carbon material nanomodifiedconcrete kinetics of cement hydration thermo-kinetic method calorimetric study https://unistroy.spbstu.ru/article/2015.34.2/ 2_frolov_34.pdf

 The foundations of offshore wind energy converters and scour protection The satisfying of North and Far-Eastern Russian offshore territories requirements in electric power is possible through the creation of the Offshore Wind Energy Converters (OWEC). The foundation for theoffshore settings can consist of concrete, steel piles and multi-supporting structures. In this article engineering measures for protection of seabed from scour near OWEC with the use of different coverings are considered. Recommendations are based on analysis of experimental studies. 10.18720/CUBS.34.3 69 offshore wind energy converters foundations scour engineering measures experimental studies https://unistroy.spbstu.ru/article/2015.34.3/ 3_nesterov_34.pdf

 Suspention cable structures and roofs of erections Suspension structures are simple in assembling, safe in maintenance, and sometimes possess the archi-tectural expressiveness. The well-known structures and buildings which had practical importance and novelty, were marked by the rewards of professional association or were passed into the top lists of journals are pre-sented in the paper. Several large crashes of large-span cable roofs did not damp the interest to them from the part of architects and designers of public and industrial buildings. 10.18720/CUBS.34.4 69 cable-laid rope;cable structures;one-layered cable covering two-layered cable covering suspension reinforced concrete shell tensile combined structure connection of intersecting cables surface of negative gauss curvature https://unistroy.spbstu.ru/article/2015.34.4/ 4_krivoshapko_34.pdf

 Maintainability waterproofing system Over the past 30 years is rapidly increasing relevance of underground construction. This is due to the large growth of megacities. Thanks to the underground construction in large cities appear new parking spaces, inturn, promotes the free movement of public transport, and help reduce traffic jams. However, underground construction faces a number of difficulties, such as exposed to water on the object. Therefore, all objects that are undertheground, should provide reliable waterproofing system. But as you know, waterproofing with time is often out of order, so you have to think in advance maintainability of the system of protection against water. This issue and devoted to this article.The article considers the effect of water on objects results the information on the materials used for the repair of waterproofing systems, the methods of waterproofing and maintainability. As maintainable system was selected waterproofing on the basis of PVC membrane LOGICROOF T-SL. By comparing the cost of waterproofing and subsequent repair of the chosen model maintainable and non-repairable systems, found the most effective solution for waterproofing of the underground part of plants. 10.18720/CUBS.34.5 69 waterproofing maintainability PVC membrane bituminous waterproofing repair waterproofing repairable formulations https://unistroy.spbstu.ru/article/2015.34.5/ 5_dalinchuk_34.pdf

 A Tower Test Station (TTS) of over head power lines (OHPL) supports and tower structures at Donbas National Academy of Civil Engineering and Architecture (DonNACEA) founded in 1997. TTS is intended for experimental studying and control of different types of OHPL supports and tower structures, and also for mechanical certification tests for an unification of new supports and foundations designs, according to international standards requirements. Researches and tests can be execut for another types of building structures, if its can be install to the force field and fit into the space served by the traction elements. Technical capabilities off TTS specified in this paper, isn’t ultimate, depend of testing structures they can be changed to the increasing direction. TTS is a part of the test center building products, constructions and structures of DonNACEA. During project of TTS have taken into account of powerlines structures development trends and the prospect of expanding its technical capabilities. By most technical indices TTS of DonNACEA exceeds the highest world Tower Test Stations. The TTS project, the testing program and tests control system designed according to international standard IEC-652. To a composition of the TTS includes universal testing hall intended for test the of individual structures and their fragments, and also alaboratory for mechanical testing of metal, building materials and structures. From 1997 to 2013 год at the TTS of DonNACEA performed series tests for different countries of the world, and a wide range of scientific experimental researches of tower structures 10.18720/CUBS.34.6 69 testing station overhead transmission line supports tower structures force field force towers drawing elements universal testing hall https://unistroy.spbstu.ru/article/2015.34.6/ 6_garanzha_34.pdf
