Investigation of the influence of the design scheme on the dynamic characteristics of the frame of a building of complex shape in plan.Method. Four variants of structural solutions for the frame of a complex-shaped building have been developed and four spatial finite element models have been built in the Lira-SAPR software package. The final elements are assigned design materials and sections. The models take into account loads and impacts in accordance with the current regulatory documentation for the selected construction area. The ground base is taken into account according to the one-parameter Winkler model.Results. Dynamic calculation of the developed models of the building frame was performed, frequencies, forms of natural oscillations, acceleration of the upper floor were obtained. The results obtained were compared with the regulatory requirements, their impact on the cost-effectiveness of the design solutions of the building under study was considered.Conclusion. The analysis of the dynamic calculation results showed that the use of several design options makes it possible to choose the most economical version of the building frame. Also, as a result of the study, it was found that cutting the frame of a complex shape in terms of simple blocks is not always effective from the point of view of optimizing dynamic characteristics.","PeriodicalId":202454,"journal":{"name":"Herald of Dagestan State Technical University.

One of the promising areas for the use of slag raw materials in the construction industry is to increase its structural instability and activity with the help of mechanochemistry. The article is devoted to the study of the combined activation of the produced (fresh) slag of steelmaking production in order to create an effective technology for obtaining cementless slag binder.Method. Steel slags were used as raw materials - energy-saturated large-tonnage waste of the West Siberian Metallurgical Plant (Novokuznetsk). As an activator waste from the coal industry of the «Abashevskaya» mine (Novokuznetsk): burnt rocks from waste heaps and sludge, obtained by lime neutralization of electrolytes of spent acid batteries, industrial transport batteries. The study of thermogravimetric curves of raw materials: \"steel slag\" and \"burnt rock\" before processing showed the characteristic features and their inherent exothermic and endothermic effects. The effect of additives-activators on the physical and chemical processes during the mechanochemical activation of steel-smelting slag has been established and main structure-forming factors.Result. Based on the used mechanically activated slag raw materials, a cementless binder of a matrix structure was obtained.Conclusion. The creation of composite binders using steel-smelting slag is relevant today as part of a large-scale task of construction and technological utilization of technogenic formations.","PeriodicalId":202454,"journal":{"name":"Herald of Dagestan State Technical University.
