Building constructions calculation models of reinforced concrete using BIM technologies

BIM technology is an information system that digitally describes not only the architectural and spatial features of the building, but also the physical, technical, functional and operational characteristics of the designed object. Automatic recalculation of changed factors is the most important feature of BIM modeling. This article is focused on developing the new methodology for calculating concrete structures using the LIRA-CAD software. It involves taking into account creep deformations in a reinforced concrete structure and deformations under the influence of temperature factors, which corresponds to the Order of the Cabinet of Ministers of Ukraine No. 152-p Kyiv "On approval of the concept for the introduction of building information modeling technologies (BIM technologies) in Ukraine and approval of the action plan for their implementation" of February 17, 2021. The comparison of the suggested calculation with the calculation given in the regulatory documents and the results obtained in the course of the experiment was carried out. Based on the results of the study, the recommendations for calculating structural elements, taking into account the effect of temperature creep were developed.
