Abstract

Throughout the development of the hydropower special attention was paid to the formation of a theoretical framework and methods of parameters and operating modes of powerhouses study. Under current design standards mathematical modeling of powerhouse is performed in two-dimensional for the axisymmetric problem. Up to now this method of simulation in Russia is the determining, although it has long lagged behind the capabilities of modern universal software of finite element analysis.The article presents analysis of the mathematical modeling methods for powerhouses of high-head hydroelectric power plants. Statement of the problem of three-dimensional modeling of the object – powerhouse is given. The procedure for multilayer three-dimensional modeling of water-conveyance conduits is presented. Outlined are the advantages of detailed numerical models of powerhouses in the context of their reliability verification.

Abstract

Тема выпускной квалификационной работы: «Бизнес-центр со сталежелезобетонным перекрытием по металлическим двутавровым балкам». В данной работе был проведен расчет и экономический анализ сталежелезобетонного перекрытия по металлическим двутавровым балкам в сравнении с железобетонным перекрытием с капителями. Задачи, которые решались в ходе исследования: 1. Замена железобетонного перекрытия с капителями на сталежелезобетонное перекрытие по металлическим двутавровым балкам; 2. Расчет сталежелезобетонного перекрытия по металлическим двутавровым балкам согласно актуальным нормам и правилам; 3. Оценка возможности использования сталежелезобетонного перекрытия в качестве альтернативы ж/б перекрытию с капителями; 4. Изучение экономической стороны вопроса и формирование вывода о целесообразности использования нового типа перекрытия в здании бизнес-центра. В результате расчета и сравнения был сделан вывод, что сталежелезобетонные перекрытия являются эффективными как в техническом, так и в экономическом аспекте, конструкциями., Theme of the final qualification work: "Business center with steel-reinforced concrete flooring over metal I-beams." In this work, a calculation and economic analysis of steel-reinforced concrete flooring over metal I-beams was carried out in comparison with reinforced concrete flooring with capitals. Tasks that were solved during the study: 1. Replacement of reinforced concrete flooring with capitals with steel-reinforced concrete flooring over metal I-beams; 2. Calculation of steel-reinforced concrete flooring on metal I-beams in accordance with current norms and rules; 3. Assessment of the possibility of using steel-reinforced concrete flooring as an alternative to reinforced concrete flooring with capitals; 4. The study of the economic side of the issue and the formation of the conclusion on the feasibility of using a new type of overlap in the building of the business center. As a result of calculation and comparison, it was concluded that steel-reinforced concrete floors are effective in both technical and economic aspects, designs.
