Уфа, РОССИЯ Аннотация: Рассмотрены области применения бетонов и арматуры повышенных классов по прочности в конструктивных элементах монолитного железобетонного каркаса. Предложены аналитические зависимости, критерии и граничные условия, численно описывающие взаимосвязь повышения прочности бетона и снижения расхода арматурной стали для изгибаемых и сжато-изгибаемых элементов. Разработаны расчетно-аналитические модели напряженно-деформированного состояния перекрытий монолитного железобетонного многоэтажного каркаса на основе проведенных многофакторных численных исследований для различных значений толщин перекрытий, пролетов, действующих нагрузок, классов бетона и арматуры. Выявлены расчетные параметры плит перекрытий, определяющие их несущую способность. На основе компьютерных технологий смоделировано оптимальное сечение железобетонного элемента по критерию снижения материалоемкости и рационального сочетания классов бетона и арматуры.Ключевые слова: программные комплексы, компьютерное моделирование, железобетон, высокопрочные бетоны, высокий класс прочности, подбор оптимального сечения железобетонного элемента, рациональное сочетание классов бетона и арматуры COMPUTER TECHNOLOGIES IN THE FORMATION OF COMPUTED MODELS OF MONOLITHIC REINFORCED CONCRETE STRUCTURES Abstract:The areas of application of concrete and reinforcement of higher grades for strength in structural elements of a monolithic reinforced concrete frame are considered. Analytic dependencies, criteria and boundary conditions are proposed that numerically describe the relationship between increasing the strength of concrete and reducing the consumption of reinforcing steel for bent and compressed-bent elements. Calculation-analytical models of the deformation state of overlaps of a monolithic reinforced concrete multi-storey frame have been developed on the basis of multifactor numerical studies carried out for various values of the thicknesses of ceilings, spans, operating loads, classes of concrete and reinforcement. Calculated parameters of slabs are determined, which determine their bearing capacity. On the basis of computer technology, the optimum section of a reinforced concrete element is modeled according to the criterion of reducing the material consumption and rational combination of classes of concrete and reinforcement.

Subject: subject of research is characterized by the requirement to master and efficiently apply CAD tools in the teaching process for analyzing reinforced concrete structures and engineering of facilities to be built under current construction standards and regulations. Objectives: consideration and analysis of updated software applications for simulation enabling to reduce academic load and improve process of education for less period of time. Methods of teaching such subjects as “Reinforced concrete and masonry structures” and “Construction engineering” are improving together with updating of simulation software, meaning consideration of the process for problem solving in calculations, engineering and mounting of reinforced frame elements to one-storey industrial facilities. Materials and methods: scientific papers by authors of this work were used as reference literature, the article methodology is based on standards of objectivity and development, statistical level of methodological analysis was applied. Results: comprehensive description for getting modern IT learning skills in using software simulation facilities was prepared under analysis of the below mentioned materials. Problems in making 3D simulation model of a frame of a building considering facilitation for the students in their appreciation and maximum approach to actual behavior of structures were reviewed either. In the course of analysis a number of assumptions was proposed for engineering of connection between bearing elements of the frame and statistical estimation in linear statement. Conclusions: bases for calculation, engineering and mounting of reinforced concrete structures were considered therewith in accordance with present norms and regulations. Currently a problem in making simulation algorithm for 3D calculation scheme of standard frame to one-storey industrial facilities is still very important.
