Abstract
Objective. 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.
