VISUAL PROGRAMMING SYSTEMS FOR ASSESSING THE SURVABILITY OF REINFORCED CONCRETE BUILDINGS

Abstract

The development of digital technologies serves as an important tool for solving urgent problems in the field of construction of new and reconstruction of existing real estate objects. The widespread introduction into practice of modern software systems that imply BIM technologies allows to avoid errors in the creation of design models of buildings and structures for the analysis of resistance to progressive collapse. This article examines the influence of the method of forming the design model on the qualitative and quantitative indicators of the parameters of the stress-strain state of the bearing system. The research methods are based on comparing the analysis results and the established parameters of the stress-strain state of the design model of a multi-storey building made of monolithic reinforced concrete when comparing them with the results of experimental studies. It was found that the use of BIM-technologies, in particular, the system of the graphic editor of algorithms for constructing the design scheme of the building using the SAPFIR-3D software complex, when analyzing the resistance to the phenomena of progressive collapse, does not reduce the quality of the executed design model. Together with a decrease in labor intensity and the number of possible errors, the use of the described technology for the formation of a computational model will reduce the time required for the design work, which will reduce the time required to prepare the necessary documentation.
